Tommy Beresford
major
Also known as Lieutenant Thomas Beresford, Thomas Beresford, Beresford, Tommy Beresford, young Beresford, Mr. Beresford, Mr. T. Beresford
Fresh out of the army and short on cash, Tommy is the steadier half of the accidental partnership Young Adventurers, Ltd., the one who recognizes faces and keeps his head while hiding behind curtains at a clandestine meeting. What he overhears there — a roomful of uneasy men, a leader who never shows his face, the whispered name Mr. Brown — turns a lark into something far more dangerous. His willingness to trust the right stranger, and his quiet instinct for when to speak and when to keep still, make him the story's unlikely hinge.
Tuppence Cowley
major
Also known as Miss Tuppence, Prudence Cowley, Miss Cowley, little Tuppence, clever little Tuppence
A vicar's daughter with no patience for the dull life waiting for her, Tuppence talks her way into an interview with a shifty businessman and walks out with the scent of a mystery. She is the one who answers the advertisement, who wires Tommy on her own ninepence, and who decides on the spot that little Tuppence can look after herself. Her quick judgment and quicker tongue drive the partnership forward, and her refusal to be frightened is exactly what the case demands.
Jane Finn
major
Also known as Miss Jane Finn, Miss Finn, the elusive Jane Finn
Jane Finn is the question everyone is asking and no one can answer: a girl who boarded a ship in 1915 carrying a secret treaty and then simply disappeared. Intelligence men, American millionaires, and criminals all want her found, and the only clue to her whereabouts is a scrap of paper and a false name. She never appears on the page in the early chapters, yet her absence pulls every character into motion and gives the hunt its stakes.
Julius P. Hersheimmer
major
Also known as Mr. Julius P. Hersheimmer, Mr. Hersheimmer, Hersheimmer, Julius, Julius Hersheimmer
Square-jawed, impatient, and refreshingly free of English circumspection, Julius arrives in London with oil money, a guilty conscience, and a missing cousin he has never laid eyes on. He mistakes Tommy and Tuppence for blackmailers, threatens to call a policeman, then offers a million dollars to find Jane — all within a single interview. His fortune and his foreignness make him both a useful ally and an obvious target, and his determination keeps the search alive when official channels stall.
Sir James Peel Edgerton
supporting
Also known as Peel Edgerton, Sir James
Sir James Peel Edgerton is the man Mr. Carter suspects is already hunting Mr. Brown without telling anyone, a barrister whose legal instincts are too strong to let him show his hand. He rings Tommy, offers him work, and trades careful questions with the Prime Minister about a disfigured body in New York. His power radiates even in a drawing room, and his willingness to call on Mrs. Vandemeyer in person suggests he knows exactly which levers to pull.
Mrs. Vandemeyer
supporting
Also known as Rita Vandemeyer, Rita, Marguerite, Vandemeyer
Tuppence's employer is a woman of means and mystery, the kind who keeps a latchkey and returns late, and whose connections run somewhere far darker than society allows. Sir James believes he can make her talk with a few well-chosen questions or, failing that, a bribe large enough to tempt her. When he calls on her at ten o'clock, the interview ends with a brandy glass and a woman on the floor — and the case turns on whatever she was about to say.
Mr. Carter
supporting
Also known as Carter
Mr. Carter moves through Whitehall with the tired manner of a man who has seen too many secrets go wrong, yet he still believes in luck and in curious young people. When Tommy recognizes him from Intelligence work in France, Carter trades his anonymity for their story, then offers expenses, a moderate screw, and one instruction: find Jane Finn. He matters because he turns the Young Adventurers from a joke into an operation, and because his refusal to explain who Jane Finn is keeps the mystery breathing.
Mr. Whittington
supporting
Also known as Mr. Edward Whittington, Whittington, Edward Whittington
Whittington presents himself as a man of affairs, the kind who can afford a good suit and a quiet room, and he approaches Tuppence with an offer that seems almost designed for her. But his questions are too pointed, his interest too sudden, and the money he dangles too large for the errand he describes. He matters because he is the first person to make the Young Adventurers feel that adventure has a price, and because his disappearance leaves behind exactly the kind of loose thread a serious reader wants pulled.
Albert
supporting
Also known as the faithful Albert
Albert is the kind of boy who says 'Yes, sir' and means it, whether he is packing a bag for Holyhead or unpacking it again five minutes later. He is not clever in the drawing-room sense, but he is loyal, quick on the stairs, and utterly unshockable about the strange errands his employers set him. He matters because the Young Adventurers cannot run their double life without someone who will carry messages, watch doors, and never ask why.
Boris Ivanovitch
supporting
Also known as Boris, Boris Something
Boris Ivanovitch is a man who gives orders and then panics when they are not obeyed, especially by Rita Vandemeyer, whose independence he cannot stomach. He fears Peel Edgerton's criminological instinct, fears exposure, and above all fears Mr. Brown, whose name he will not quite say aloud. He matters because his quarrel with Mrs. Vandemeyer, overheard by Tuppence, confirms the conspiracy is real and that its members are already watching one another.
Kramenin
supporting
Also known as Monsieur Kramenin
Kramenin receives visitors in a suite at Claridge's, dictates to a secretary, and measures men by their fortunes, but when Julius Hersheimmer produces a revolver his composure collapses entirely. He has seen Mr. Brown, spoken to him face to face without knowing it, and that memory makes him more afraid of his own master than of any American millionaire. He matters because his confession names Astley Priors and confirms that Jane Finn is a prisoner, not a runaway.
Dr. Hall
minor
Also known as Hall
Doctor who treats a key character.
Danvers
minor
Also known as Mr. Danvers
Government official involved in the secret mission.
Conrad
minor
Also known as Monsieur Conrad, the silent Conrad
Servant at the house in Soho.
Janet Vandemeyer
minor
Also known as Miss Janet Vandemeyer, Miss Vandemeyer, Annette
Maid who becomes a key witness.
Mr. Brown
supporting
Also known as Brown, the elusive Mr. Brown
No one in the gang can describe Mr. Brown, and that is precisely his power: he is a rumor that has learned to give orders, a password Tommy chances upon and survives by repeating. Kramenin has seen him in a crowd and cannot identify him; Boris speaks of his vengeance in a lowered voice. He matters because every thread of the conspiracy, from Whittington's offer to Jane Finn's captivity, seems to run back to a man who may be anyone in the room.
Count Stepanov
minor
Russian count involved in the plot.
Nurse Edith
minor
Also known as Edith
Nurse attending a patient.
George
minor
Servant at the Beresford household.
Inspector Brown
minor
Police inspector investigating the case.
