Hercule Poirot
major
Also known as Monsieur Poirot, Poirot, the great Hercule Poirot, Monsieur Hercule Poirot, Papa Poirot
Poirot is the retired policeman whose little grey cells have made him a society fad, complete with a mocking notice in Society Gossip and a stream of fashionable clients at his door. Laid low by influenza, he still orchestrates investigations by dispatching Hastings to Derbyshire and demanding daily reports, his vanity and his method inseparable. His refusal to leave his bed while solving a murder is the engine of the book's early cases: the mind travels where the body cannot.
Captain Hastings
supporting
Also known as Hastings, the good Hastings, Mon ami Hastings
Hastings is Poirot's partner and narrator, a man who sees a glamorous woman trailed by strangers and instantly invents a crime drama. He trusts beautiful women, leaps at the chance to carry a revolver, and is repeatedly deflated by Poirot's sly corrections, as when a porter proves the Robinsons have lived in Montagu Mansions for six months. His credulity is the reader's own, and his wounded dignity makes the deductions land harder.
Inspector Japp
supporting
Also known as Japp, the good Japp
Japp is the professional policeman whose cases keep colliding with Poirot's amateur genius, and he knows better than to resent it. He brings the weight of the Yard but yields the final word to the little Belgian, a working partnership built on grudging respect. His presence grounds the stories in real police machinery, making Poirot's leaps feel like triumphs over method rather than mere cleverness.
Miss Mary Marvell
supporting
Also known as Mary Marvell, Miss Marvell, Mary
Mary Marvell arrives in England with her actor husband Gregory Rolf to a reception bordering on hysteria, her furs and jewels the talk of the town. She is followed through the streets by a bevy of admirers she is perfectly aware of, and she comes to Poirot because her prized Western Star is at the center of a threat. Her glamour is the bait, and her jewel the puzzle: a public woman whose private fear drives the case forward.
Lady Yardly
supporting
Lady Yardly belongs to the world of titles and country houses that the Western Star case cuts across, her diamond set against Mary Marvell's in a contest of possession and prestige. She is caught between the discretion her rank demands and the danger circling the stone, a woman whose composure may conceal more than it shows. Her stake in the jewel makes the theft personal, widening the mystery from a single actress's panic to a clash of two very different worlds.
Lord Yardly
minor
Also known as the present Lord Yardly, Yardly
The current Lord Yardly, husband of Lady Yardly.
Mr. Philip Ridgeway
supporting
Also known as Philip, Mr. Ridgeway, Ridgeway, Philip Ridgeway
Ridgeway is the respectable, conscientious bank official through whom a fortune in negotiable bonds passes, a man whose whole career rests on being trusted. When the bonds vanish, his professional world and his personal honor are suddenly on the line, and he must submit to Poirot's scrutiny to clear himself. He is the human cost of the case: a solid man made desperate by a theft that looks, at first, like his own failure.
Mr. Davenheim
supporting
Also known as Mr. Poirot, Mr. Davenheim Poirot, Davenheim
Davenheim keeps The Cedars, a palatial country place at Chingside, and his habits are so regular that his disappearance reads like a hole cut out of the day itself. He tells his wife he is walking to the village to post letters and expects a business caller named Lowen; a quarter of an hour later a dark man with a thick moustache arrives and waits in the study for a host who never returns. The broken safe, the locked windows, and the missing bearer bonds turn a domestic puzzle into the case Poirot must untangle.
Mrs. Davenheim
minor
Also known as Madame Davenheim, Madame
The wife of the missing banker Mr. Davenheim.
Count Foscatini
supporting
Also known as the late Count Foscatini, Foscatini, the Count, The Count
Foscatini lives quietly in London attended by his manservant Graves, and his affairs are orderly enough that his pocketbook holds the address of the man who will be suspected of killing him. Two Italians call on him with what Graves overhears as a monetary proposition built on a threat; the Count coolly postpones the argument to a dinner at eight. When he sends his servant out for the evening, the gesture signals a business too unusual to be witnessed, and the stopped clock on his writing-table fixes the hour of his death.
Signor Ascanio
minor
Also known as Signor Paolo Ascanio, Ascanio
An Italian man involved in the Count Foscatini case.
Mr. Roger Havering
supporting
Also known as Roger Havering, Mr. Havering, Havering
Havering moves through the world of fashionable London, where reputations are made of furs, jewels, and the right introductions, and where a robbery at a grand hotel becomes a social event as much as a crime. He is the kind of man whose ease in that world makes him useful and slightly suspect at once, since Poirot's cases turn on who noticed what and who chose not to. His presence gives the investigation its human texture, a reminder that theft among the wealthy is rarely only about the object taken.
Mrs. Opalsen
minor
Also known as Opalsen
A wealthy woman whose pearls are stolen at the Grand Metropolitan.
Mr. Opalsen
minor
The husband of Mrs. Opalsen, present during the jewel theft.
Mr. Bleibner
supporting
Also known as young Mr. Bleibner, young Bleibner
Young Bleibner belongs to the moneyed transatlantic set that treats archaeology as spectacle, and his name surfaces in the orbit of a discovery that has already made men nervous. He is caught between the glamour of the expedition and the ugly rumors that trail it, a tension that sharpens once the tomb's treasures begin to exact their price. His involvement gives Poirot a living thread to pull, since the dead of ancient Egypt are far easier to blame than the living who profit by them.
Sir Guy Willard
minor
Also known as Sir Guy, Willard
A government official involved in the kidnapping of the Prime Minister.
Mr. Bernard Dodge
minor
Also known as Mr. Dodge, Dodge

Miss Violet Marsh
supporting
Also known as Miss Marsh, Miss Violet, Violet Marsh
Violet Marsh dresses plainly but neatly and carries herself with the assurance of someone used to being taken seriously, which makes her uncle's final testament all the more galling. The will leaves her a puzzle rather than a fortune, and she comes to Poirot not as a supplicant but as a client with a case to argue. Her steadiness gives the mystery its spine, since the question of whether she can outthink a dead man's joke is the question the story asks.
