“Appearances are deceptive, they say…” (22).
As the third official book in Agatha Christie’s Hercule Poirot series, Poirot Investigates offers a charming, concise collection of short stories showcasing Poirot’s unrequited “grey cells” and his unparalleled “method” of sleuthing. In total, there are fourteen short stories in this collection, many of them feature tales of mysterious disappearances, jewelry heists, murders, stolen inheritances, ghostly superstitions, and even the kidnapping of the Prime Minister of England. The indomitable Inspector Japp of Scotland Yard makes a few cameos in these stories alongside Poirot, and throughout them all, Captain Hastings comes across as his usual slightly stultified self with a tone of exasperation and resentment toward Poirot. Whenever he attempts to “help” solve a case without Poirot’s presence, he seems to only unwittingly ruin the case or cause further mayhem. As a somewhat frivolous comedic relief character (and also ironically the narrator of the stories), Hastings frequently comments on his old-fashioned social and political views, and often expresses a subtle degree of mild contempt for Poirot’s brilliance. In addition to Hastings, there are a few other familiar faces in the Poirot universe who have cameos in these tales, such as Mary Cavendish who was featured prominently in The Mysterious Affair at Styles.
Generally speaking, I would submit that these short stories are not canonically vital to the casual Poirot reader. While they offer a string of charming, intriguing, mostly low-stakes mysteries, Poirot Investigates simply doesn’t carry the same gravitas as Christie’s longer works, like The Murder of Roger Ackroyd (1926) or Murder on the Orient Express (1934). With that being said, Poirot Investigates comes highly recommended. Interestingly enough, three of these short stories first appeared in the American publication of this book (“The Chocolate Box,” “The Veiled Box,” and “The Lost Mine”), they weren’t published together in the UK until Poirot’s Early Cases was published in 1974.
As one final introductory note, Poirot Investigates continues to examine the character of Poirot as an investigator who also has a deep sense of propriety. In one case, he decides against revealing a woman’s indiscretions to her family, and in another he freely decides to break-into a house under false pretenses and ransack the place in order to solve a mystery. While Poirot represents a mix of a Socratic inquirer and Enlightenment rationalist, he is also deeply in touch with common sense and moral awareness in each situation. He seems to see a hidden world of “cause and effect” in these case, one that is entirely foreign to a man like Hastings.
I’d say my favorite short stories in this collection include “The Adventure of the Egyptian Tomb,” a spooky tale and fascinating examination of superstition as well as the extent to which Poirot considers himself to be a superstitious man; “The Kidnapped Prime Minister” for its high-stakes international mystery concerning the disappearance of the Prime Minister of England; and other stories like “The Disappearance of Mr. Davenheim” and “The Jewel Robbery at the Grand Metropolitan.”
#1 The Adventure of the “Western Star”
Popular actress Miss Mary Marvell arrives at Poirot’s flat to speak with Poirot and Hastings about a trio of ominous threatening letters she has received from a “Chinaman” seemingly about her prized jewel “The Western Star,” purchased from a Chinese man in San Francisco. She has been referred to Poirot by one Lord Cronshow after Poirot solved mystery of his nephew’s death. She is married to film actor Gregory B. Rolf, and while typically keeping the jewel in a safe at their hotel, The Magnificent, but tonight they plan to take it to Yardly Chase where she plans to film a feudal piece with Lord and Lady Yardly. The Yardlys have another Chinese stone known as “The Star of the East.” According to legend, when the Stars if the East and West meet again, they shall return un triumph to the god.
Next, Poirot departs and Lady Yardly visits the flat (sent by Mary Cavendish, the wife of John Cavendish who appears in Agatha Christie’s earlier Poirot novel The Mysterious Affair at Styles) but Hastings believes he can serve her inquiry without the presence Poirot –“I, too, possess the deductive sense in a marked degree” (12). He unwisely reveals all the details from the conversation with Mary Marvell from that morning. Later at Yardly Chase, as Lady Yardly leaves to get dressed, all the lights go out and suddenly a scream is heard as the group finds Lady senseless on the floor with a crimson mark on her throat and the prized necklace wrenched away. The necklace was dropped and the “Star of the East” diamond is missing as Lady Yardly believes she saw an embroidered robe and pigtail believes it to be a “Chinaman.” The next day, Mary’s jewel is stolen from her hotel room, as well.
What happened here? Agatha Christie brilliantly weaves this tale together with elements of suspicion as well as mysterious supernatural elements (like visiting the Yardly Chase estate on the next full moon), however it is also a quintessential example of a story filled with “Orientalist” prejudice.
Spoilers Ahead
Poirot rather easily solves this little caper, no thanks to Hastings who is apparently in a “fog.”As it turns out, three years ago Rolf had an affair with Lady Yardly in the United States and blackmailed her into giving him the prized diamond so that he might pass it along to his wife as a wedding gift. Now, Lady Yardly’s husband, who is in debt, has been wanting to sell the diamond, thus Lady Yardly has been demanding it back from Rolf. And so, it was Rolf who concocted this elaborate scheme about two diamonds of the “East” and “West” in order to secretly return the diamond to Lady Yardly. He also painted grease at the corner of his eyes to appear to be more Chinese (in an unfortunate flirtation with racism). Of course, the ever-clumsy Hastings played a role in this plot when he accidentally revealed some of the truth to her. Once again with Poirot we learn that method is key –Hastings simply does not understand the art of secrecy, the need for esotericism. Hastings ends the story “fed up” because Poirot has “gone too far this time.”
#2 The Tragedy at Marsdon Manor
Poirot has been called away to investigate a case for the Northern Union Insurance Company –Mr. Maltavers was found dead “slightly past the prime of life” at his Essex estate Marsdon Manor, but he bought a fifty-thousand-pound life insurance policy a few weeks ago. There was a suicide clause in the policy: that if he killed himself within a year the premiums for his young wife would be forfeited. Poirot’s old friend Alfred Wright has summoned him to investigate.
They question Dr. Bernard who is eager to be rid of them. Reportedly, Mr. Maltravers died of an internal hemorrhage. Then a mysterious man named Captain Black arrives and Poirot begins to have his suspicions.
Spoilers Ahead
Poirot discovers that it was actually a bullet that caused Mr. Maltravers internal hemorrhage, however he is not convinced it was a suicide. Poirot stages a ruse based on the popular ghost stories about Marsdon Manor wherein a friend dresses up like the late Mr. Matravers and enters the house in the dark while pointing a finger at his wife. In terror, his wife admits to killing her husband. She compelled her husband to acquire a life insurance policy and then while out hunting with a rifle, she playfully convinced him to place the gun in his mouth himself and then pulled the trigger.
#3 The Adventure of the Cheap Flat
Hastings was spending the evening with an old friend, Gerald Parker, when conversation turned to flats –in particular a deal on a flat in “Montagu Mansions” in Knightsbridge rented by Mrs. Stella Robinson and her husband. Why were they able to rent such a cheap flat? Is it haunted as the rumors suggest? Or is something wrong with the flat? Hastings attempts to solve the mysterious situation –“I rather wished Poirot had been there. Sometimes I have the feeling that he rather underestimates my capabilities” (48).
But when he brings the story to Poirot the following morning, Poirot decides to take up the case since he suspects something nefarious…
Spoilers Ahead
From Inspector Japp, Poirot learns of American naval plans stolen by an Italian named Luigi Valdarno who passed them to a spy for Japan, a striking woman with auburn hair named Elsa Hardt before Valdarno was killed. Elsa and her accomplice then fled to the United States. As it turns out, Hastings’s friends were given a cheap flat and were being targeted by an Italian gang, believing Mrs. Stella Robinson was Elsa Hardt. Poirot exposes the real culprits and reveals that the plans are being held in a cat before he meets of Mr. Burt of the United States Secret Service. Not unlike a Hitchcock film, this rather innocuous story of a cheap flat turned into an international espionage tale solved by Poirot and his “grey cells.”
#4 The Mystery of Hunter’s Lodge
“After all… it is possible that I shall not die this time” murmurs Poirot as a convalescent influenza patient (recall that Hastings previously suffered from the disease as described in The Mysterious Affair at Styles). “Once more shall I be myself again, the great Hercule Poirot, the terror of evildoers! Figure to yourself, mona mi, that I have a little paragraph to myself in Society Gossip. But yes! Here it is: ‘Go it –criminals—all out! Hercule Poirot –and believe me, girls, he’s some Hercules! –our own pet society detective can’t get a grip on you. ‘Cause why? ‘Cause he’s got la grippe on himself!’” (63).
Then, Roger Havering, son of the fifth Baron of Windsor, arrives. He explains that his uncle, Harrington Pace, was murdered last night in Derbyshire at a place called Hunter’s Lodge, a hunting property. When Hastings arrives in Poirot’s stead, Inspector Japp is also on the scene. A mysterious bearded American is suspected because he entered the house and the gun room. Poirot sends a telegram requesting that Japp arrest the housekeeper, Mrs. Middleton, right away before it’s too late! But sadly, it is too late. She has vanished. Havering’s wife, Zoe Havering, describes how Mrs. Middleton was recently hired, only three weeks on the job, but the agency has no record of Mrs. Middleton. In defeat, Hastings returns to London.
Spoilers Ahead
Back in London, Poirot reveals the truth –Zoe Havering was a former actress and it was actually she who dressed as a housekeeper in the shadows (there was no Mrs. Middleton) and Roger Havering was in on the murder because he was set to inherit his uncle’s vast fortune (also Poirot highlights a discrepancy with the murder weapon, a revolver). But in the end, even though Poirot and Hastings could not act further in the case, justice is served when Roger and Zoe Havering are killed in an Air Mail crash. “’The wicked flourish like a green bay tree,’ I reminded him.’ ‘But at a price, Hastings, always a price, croyez-moi!’”
#5 The Million Dollar Bond Robbery
Hastings begins by noting an influx of bond robberies recently when Miss Esmee Farquhar stop by to discuss the theft of Liberty Bonds on the transatlantic oceanliner Olympia. She is engaged to Mr. Philip Ridgeway who is in charge of bonds when they were stolen. Appointed Mr. Vavasour, general manager of the Scottish and London Bank. Someone tried to sneak into his safe on the ship and by the time they arrived in New York, the bonds were missing.
Spoilers Ahead
Poirot discovers that another ship, the Gigantic, left Southampton around the same time and arrived slightly earlier than the Olympia. Mr. Vavasour’s compatriot pretended to be an invalid on the ship, made the obvious break-in markings, but stole the bonds back at the bank and sent them on the Gigantic while giving a dummy files to Ridgeway to carry over the Atlantic. He has been at home with bronchitis as a cover for his theft!
#6 The Adventure of the Egyptian Tomb
Hastings described this adventure as one of the most “thrilling” and “dramatic of his many adventures with Poirot. It concerns a strange series pf deaths after the opening of the tomb of King Men-her-Ra, believed to be one of the shadowy kings of the Eighth Dynasty when the Old Kingdom was falling to decay, following the discovery of the tomb of Tutankh-Amen by Lord Carnarvon, Sir John Willard, and Mr. Bliebner of New York within the pyramids of Gizeh (not far from Cairo).
Shortly thereafter, Sir John Willard died quite suddenly of a heart attack, then Mr. Bliebner died of acute blood poisoning, and a few days later, his nephew shot himself. The “Curse of Men-her-Ra” spread like wildfire in the newspaper, spawning renewed superstitions. Within this context, Lady Willard, widow of the late archaeologist, contacted Poirot and asked to meet him at her house in Kensington Square –fearful of all he supernatural rumors swirling around, she fears for the life of her son, an Oxford man who intends to take his father’s position on the archaeological dig. Surprisingly, perhaps to assuage Lady Willard’s fears, Poirot admits to accepting the “force of superstition” himself, and he wonders if the counter-efforts against black magic in the Middle Ages might not necessarily be inferior to our modern age of science. Do we believe Poirot? He is carrying a book called The Magic of the Egyptians and Chaldeans.
Hastings and Poirot travel to Egypt by way of Marseilles to Alexandria and on to Cairo (Poirot is apparently a terrible traveler) where they learn that another person has died, this time of tetanus. After meeting the crew onsite, at night they witness a strange non-human shadowy figure of Anubis, the jackal-headed god of departing souls.
Spoilers Ahead
In the evening after receiving his chamomile tea, Poirot discovers the murderer is actually Dr. Robert Ames, the onsite medical practitioner, who finagled his way into inheriting wealth from the deceased. And regarding the question of supernatural superstitions, Poirot admits to Hastings that he merely believes “in the terrific force of superstition” which can be taken advantage of by clever liars like Dr. Ames.
#7 The Jewel Robbery at the Grand Metropolitan
Despite Hastings being slightly annoyed at the fact that Poirot does not take him too seriously, Hastings invites Poirot to a weekend at the Grand Metropolitan because “a change of air” might do him good. And when they arrive in Brighton, “All the world and his wife seemed to be at Brighton. The dresses were marvellous, and the jewels –worn sometimes with more love of display than good taste—were something magnificent” (110). Across the room, they spot Mrs. Opalsen donning many large jewels, she is the wife of a rich stockbroker who made his wealth in the recent oil boom.
However, soon Mrs. Opalsen’s prized pearl necklace is stolen despite the supposed presence of Celestine, the French maid, and the chambermaid. When the pearls are found hiding in Celestine’s mattress, she is detained for the robbery. But Poirot remains unconvinced…
Spoilers Ahead
Poirot suspects that the pearls have been planted in Celestine’s bed, and he successfully uncovers a plot between the chambermaid and the valet, involving a duplicate key, and in the end, it is an undusted adjoining room that gives away the secret (along with a card with fake fingerprints on it). As the story concludes, Poirot reveals he has been given a small financial reward from Mrs. Opalsen.
#8 The Kidnapped Prime Minister
“Now that war and the problems of war are things of the past, I think I may safely venture to reveal to the world the part which my friend Poirot played in a moment of national crisis,” so says Captain Hastings. This story takes place back when “peace by negotiation” was a popular mantra, during World War I, as Hastings was given a recruiting job after being invalided out of the army, when Mr. David “Fighting Mac” MacAdam, Prime Minister of England. We find Hercule busily mopping his grey suit with a sponge –“Never was there a dandy such as Hercule Poirot.” Then suddenly two men arrive: Lord Estair, Leader of the House of Commons, and Mr. Bernard Dodge, a member of the War Cabinet and a close personal friend of the Prime Minister. The Prime Minister has been kidnapped in France, while bandaged at the head, and there is a vitally important Allied Conference occurring tomorrow (Thursday) in Versailles. Also, there was a recent attempt on his life and his chauffeur O’Murphy has also disappeared. Is this the work of German agents?
Along the way, Poirot and Hastings encounter an old friend, Detective Inspector Japp of Scotland Yard and this sets up a friendly competition between Poirot and another man from Scotland Yard, Major Norman. After a lengthy period of time using his “grey cells,” Poirot returns to England where he believes he can better solve the case. Why?
Spoilers Ahead
Poirot discovers that the Prime Minister never actually left England, he was kidnapped from Windsor to London, chloroformed by the “clever linguistic” Captain Daniels (MacAdams’ Secretary). Both the Prime Minister and his chauffeur O’Murphy were drugged and replaced by substitutes, bound in bandages to France. Later, David MacAdam is also found. A short time later, the newspapers report on a successful Allied Conference, in particular a rousing speech by David MacAdam.
#9 The Disappearance of Mr. Davenheim
Poirot and Hastings enjoy tea with their old friend, Inspector Japp of Scotland Yard while they discuss the news of the strange disappearance of Mr. Davenheim, senior partner of Davenheim and Salmon, well-known bankers and financiers. He went out walking one morning and simply disappeared. How could this happen? Poirot discusses three types of disappearances: 1) the most common is a voluntary disappearance 2) the much-abused “loss of memory” case 3) murder and a, more less, successful disposal of the body.
Can Poirot solve the mystery? For this, he will need to use his “method” of rigid scientific calculation, seeking the truth “within, not without.” Poirot intends to solve the mystery without leaving his chair –Japp bets him a fiver he cannot. That day, Davenheim was scheduled to meet with a speculator named Lowen who held a grudge against Davenheim, but Davenheim disappears shortly before their meeting is scheduled and his private safe is robbed, filled with bonds, money, and his wife’s jewelry collection. Naturally, Lowen is arrested under suspicion. However, Poirot inquires as to whether the Davenheims occupy separate bedrooms, and he asks about a trip Davenheim made to Buenos Aires… and a petty criminal named Billy Kellet comes to light for pawning Davenheim’s prized ring (Kellett is arrested) and Mr. Davnheim’s clothes are found in the lake near his house. What could have happened to Mr. Davenheim? Was he kidnapped or murdered by Lowen? Was his wife involved? Or was Billy Kellett part of the plot?
Spoilers Ahead
Poirot surprises everyone by accurately predicting the Davenheim and Salmon bank failure. As it turns out, Davenheim was secretly embezzling funds from the bank and using the stolen funds to buy bonds and jewelry, hiding them in his safe, and he changed his appearance significantly and took on the identity of Billy Kellett in order to get arrested and be escape suspicion while awaiting his chance to start a new life with the funds he took from his own safe (he set-up Lowen to seem guilty). The spare change of clothes were deposited in the lake by Davenheim himself.
In the end, Japp gives Poirot a five-pound note per their agreement.
#10 The Adventure of the Italian Nobleman
In early June, a friend and neighbor, Dr. Hawker, drops in on Poirot and Hastings for a discussion of the frequent use of arsenic poisoning in recent crimes when his housemaid Miss Rider suddenly bursts into the room. She has received an urgent call for help from a man named Count Foscatini in Regent’s Court who claims “they have killed me!” Dr. Hawker brings Poirot and Hastings to Foscatini’s flat where he had been meeting with two allegedly foreign men, only to find Foscatini “stone dead” still clutching the phone. First, Poirot visits the kitchen and then inquires about Foscatini’s manservant named Graves and one of Foscatini’s dinner guests, Signor Ascanio. What happened here?
Spoilers Ahead
As it turns out, Foscatini was blackmailing Signor Ascanio but it was Graves who killed his employer (one of the revealing clues is the curtains which are left open). Poirot passes his solution on to Inspector Japp who proves Poirot to be correct.
#11 The Case of the Missing Will
Miss Violet Marsh, a tall businesslike woman calls upon Poirot (Hastings amusingly confesses to not being impressed with her since she is a “New Woman” and Hastings is something of a traditionalist simpleton). Miss Marsh explains she was an orphan, her father’s elder rother Andrew emigrated to Australia and became rich by means of land speculation. Both her parents died by the time she became a teenager and she was taken in by her uncle Andrew who returned to England. However, he disapproved of her decision to get an education (like Hastings, he was disapproving of the education of women). He died about a month ago, and left behind a strange will in which he leaves his estate Crabtree Manor to Miss Marsh for one year during which time can prove her wits, but if she fails the test, the estate will pass to various charitable institutions.
Poirot and Hastings then endeavor to hopefully discover another will which might undo his rudimentary one giving Miss Marsh only a year outwit him. They travel to Crabtree Manor in Devonshire and speak with the housekeepers, Mr. and Mrs. Baker. In the late Mr. Marsh’s study, Poirot finds an orderly desk with a key and an empty envelope. From here, they learn that workmen were hired to conduct work on Mr. Marsh’s furnace, but when Poirot and Hastings look in a cavity only to find a burnt copy of his will. What could have happened?
Spoilers Ahead
Poirot discovers that hiring the workmen was merely an elaborate distraction and the overriding will is actually published in invisible ink on the envelope on his desk. Miss Marsh has proven her wits by hiring an expert like Poirot.
#12 The Veiled Lady
With no interesting cases of late, not even a case of jewelry theft on Bond Street, Poirot laments that criminals are beginning to fear him –when suddenly, a veiled lady arrives at their flat. She is Lady Millicent Castle Vaughan, recently engaged to the Duke of Southshire. She once wrote an indiscreet letter to a young soldier who was killed in the war. Now, she is being blackmailed by Mr. Lavington, who threatens to reveal the letter to the Duke unless Lady Millicent releasees a large sum of money. In accepting the case, Poirot and Hastings find her letter concealed inside a Chinese box in a wooden log in the coal bin… but is this the end of the story?
Spoilers Ahead
Inside the Chinese box, Poirot reads Lady Millicent’s amorous letter but in another chamber of the box he finds a pair of jewels. Inspector Japp steps out of Poirot’s room and arrests Lady Millicent for the Bond Street jewelry theft. Poirot says he knew she was a fraud right away by the shoes she was wearing, revealing herself not to be a woman of class.
#13 The Lost Mine
The delightful short story concerns Hastings over-drafting his bank account, and he considers investing in Porcupine Oil Wells while Poirot prefers not to consider speculative investments, as exemplified in an award he received of Burma Mines Ltd., one hundred miles inland from Rangoon. In this case, a member of an enterprising Chinese family, Wu Ling, travels to England to meet with the board of the company, but his body later turns up in the Thames. At this point, Poirot is called in to investigate by Mr. Pearson of the corporate board, and he is joined by the insufferable Inspector Miller. What happened here?
Spoilers Ahead
In a rather simple mystery, the culprit is shown to be Mr. Pearson and Poirot was granted fourteen thousand shares in the Burmese mine as repayment for solving the case. The lesson for Mr. Pearson is to be conservative with his investments. This is a charming, albeit simplistic, framed mystery tale told as a recollection by Poirot.
#14 The Chocolate Box
On a cold, windy night, Hastings asks if Poirot has ever failed a case, to which Poirot responds with a story from long ago in Belgium in which he investigated a French deputy named M. Paul Déroulard. We learn that Déroulard inherited an estate from his late wife, but then died himself shortly thereafter. This took place during the raging conflicts between Catholics and Protestants (Poirot was/is Catholic). Suspicion turns to a poisoning via a chocolate box, but did Poirot actually make a mistake in solving this one?
Spoilers Ahead
Poirot turns to another man, M. de Saint Alard, whom he accuses for the poisoning of Déroulard, but strangely Déroulard’s elderly and infirm mother confesses to the crime due to her accidental mix-up of items, and she dies a week later. Apparently, it was an accidental killing.
