Edition details
Book Summary
When Cabinet Minister John Hoode is brutally murdered in his study, newspaper editor Spencer Hastings recruits the brilliant Anthony Gethryn to investigate. Gethryn navigates a web of secrets, blackmail, and misleading clues to uncover the truth, ultimately revealing a shocking case of mistaken identity and hidden guilt.
The novel opens with the murder of John Hoode, a Cabinet Minister, at his country home Marling. Spencer Hastings, editor of *The Owl*, sends his friend Anthony Gethryn, a polymath and former intelligence officer, to investigate. Gethryn arrives to find the police focused on circumstantial evidence pointing to Archie Deacon, a young man with a motive. Through interviews with household members—including the butler Poole, Hoode's sister Laura, and a mysterious performer named Madam Vander—Gethryn uncovers secrets: Hoode had a hidden mistress, stolen love letters, and an illegitimate half-brother. He discovers that the body is not Hoode's but his half-brother's, and that Hoode faked his death to escape blackmail. The true culprit is Sir Arthur Digby-Coates, who killed the half-brother in a fit of madness. Gethryn proves Deacon's innocence, secures a confession, and resolves the case. Meanwhile, a romantic subplot develops between Gethryn and Lucia Lemesurier, culminating in their engagement.

Narrative arc
Story tension across the book.
Anthony Gethryn
Gethryn moves through Marling as an old friend of the Yard and a gentleman of the village, which lets him press Boyd for the wood-rasp and the fingerprint enlargements while everyone else considers the murder solved. He admits he is groping in the dark, yet the certainty of his doubt — that Deacon's guilt is too neat, too convenient — sets him against the official story. His stubborn refusal to accept an easy answer is the engine that keeps the case from closing in the early chapters.
Sir Arthur Digby-Coates
Sir Arthur is the deceased's closest friend and a guest at Abbotshall, and he throws himself into the investigation with a rage that startles even Gethryn — he speaks of torture, of sleepless nights, of getting his hands on the animal who did it. He also quietly arranges books, cigars, and Marshall, K.C. for the man accused of the crime, a generosity that sits oddly beside his fury. His grief and his interventions keep the reader guessing where his loyalties truly lie.
Mr. Deacon
Deacon is the man Scotland Yard has all but convicted: his alibi is broken, a hundred pounds from the dead man's bank sits in his collar-box, and his prints are on the wood-rasp. Yet he faces it with a composure that moves Gethryn — books, cigars, and a good counsel arranged, and a steady insistence that it will all come right. His courage and the suspicious neatness of the evidence against him make him the emotional center of the early mystery.
Lucia Lemesurier
Lucia is Dora's older sister, the composed one, the one who consoles — except that half her mind is elsewhere, tangled in a note that went unanswered and a man she barely knows. She is mortified by her own distraction, and her private thoughts about Gethryn (not fat, not white-moustached, but lean and hawky with disturbing eyes) betray an attraction she refuses to name. Her divided attention makes her the quiet emotional counterweight to the murder's noise.
Colonel Gethryn
Boyd is the official investigator, methodical and a little proud of a case he considers 'easy,' and he walks Gethryn through the locked-room problem, the open window, and the wood-rasp with the air of a man who has already closed the file. He is loyal enough to share the fingerprint enlargements and to ask Gethryn to keep quiet about them, and honest enough to admit the case has a nasty, puzzling feel. His friction with Gethryn — the sane law versus the mad amateur — gives the early investigation its productive tension.
Miss Margaret Warren
Miss Warren works for Hastings at The Owl, and she is the one who brings the first word of Hoode's murder — calm, unemotional, already thinking about the next edition. She is so sufficient, so calmly adequate, that Hastings sometimes wishes she weren't, and the one glimpse of her trembling and white-faced pleases him in a way he doesn't examine. Her competence and her single crack of feeling make her the newsroom's quiet anchor in the opening chapters.
Justice and Injustice
The book explores the tension between circumstantial evidence and true guilt, as the protagonist Anthony Gethryn works to prove the innocence of Archibald Deacon, who is wrongly accused of murder based on fingerprints and motive.
Appearance vs. Reality
Characters and clues repeatedly mislead; the seemingly obvious suspect (Deacon) is innocent, while the true murderer is hidden among the household, and the wood-rasp's mark on the table reveals a crucial discrepancy between how the crime appears and what actually happened.
Class and Social Hierarchy
The narrative examines the rigid British class structure through the household at Abbotshall, with servants, the gentry, and a Cabinet Minister, and how suspicion falls differently based on social standing.
The Role of the Press
The book highlights the power and sensationalism of journalism, as seen through Spencer Hastings' newspaper *The Owl*, which profits from the murder and shapes public opinion, while also aiding the investigation.
