Edition details
Book Summary
A journalist and a detective investigate the locked-room murder of a reclusive miser, Jesse Trasmere, uncovering a web of secrets involving a Chinese restaurateur, a stolen jewel case, and a madman's vanity. The case spirals into obsession, betrayal, and a dramatic confrontation.
Tab Holland, a journalist, and Inspector Carver probe the death of Jesse Trasmere, found dead in a locked vault with a blood-stained key. Suspicion falls on Trasmere's valet Walters, but clues—a bent pin, a celluloid cap, and Ursula Ardfern's stolen jewels hidden in the vault—point deeper. Tab discovers his friend Rex Lander is secretly infatuated with Ursula and that Yeh Ling, a Chinese restaurateur, has a hidden past with Trasmere. Rex confesses to murdering Trasmere and Wellington Brown, motivated by his obsession with Ursula and need for money. He traps Tab in a vault and sets a fire, but Tab is rescued. Rex then attempts to force Ursula into marriage but is killed by Yeh Ling, who encases the body in concrete. Carver deduces Rex's guilt, and the story ends with Yeh Ling hosting a party, his secret intact.

Narrative arc
Story tension across the book.
Tab Holland
Tab Holland moves between Fleet Street and Hertford, close enough to the Trasmere case to be useful and smitten enough with Ursula Ardfern to be reckless. When she asks him to quietly sell her jewels and give the money away, his devotion collides with a story he can't quite name. His access to both the press and the household makes him the reader's natural guide through the case's first half.
Rex Lander
Rex Lander drifts through the case as the charming heir, quick to congratulate Tab on winning Ursula and quicker to insist he isn't hurt. His alibi is Rome; his sapphire ring was bought near Doughty Street, and a Chinese-issue revolver turns up in his rooms. The gap between his performance of carefree friendship and the evidence piling up around him is the tension that keeps the middle of the book humming.
Ursula Ardfern
Ursula Ardfern lives outside Hertford in a house with a Chinese garden, pale and thinner than when Tab first saw her, and speaks of money with the weariness of someone who has had too much of it. She wants her Trasmere jewels sold and the proceeds distributed anonymously, refusing to be named as the donor. Her composure and her refusal to explain herself are what draw Tab in — and what make her eventual confession land like a dropped stone.
Inspector Carver
Inspector Carver moves through the case with the patience of a man who has learned not to show his hand. He lets a nervous visitor talk for three hours and tells no one; he sits with Yeh Ling over cigars and asks for documents he knows he won't get. His quiet accumulation of evidence — the revolver, the receipt, the torn photographs — is what turns a locked-room puzzle into a pursuit.
Yeh Ling
Yeh Ling is a successful Chinaman in the restaurant trade, monosyllabic with reporters and unhurried with police, who keeps a safe of Trasmere's papers and refuses to hand over one of them. He visits opium dens in Reed Street without flinching at the jeers, and he protects Ursula Ardfern with a loyalty that has its own logic. His silence is not ignorance — it is a decision, and it shapes what Carver can and cannot prove.
Jesse Trasmere
Jesse Trasmere lives by ritual: up at two, out at six-thirty with an umbrella and a black bag, home at eight-thirty, coffee at ten, the valet's door locked behind him. He bought his furniture secondhand and boasts of the bargain; he keeps no books and reads no newspapers. His fortune, his Chinese connections, and the vault beneath his house are the three facts the case turns on — and his death is the question every other character is trying to answer.
Identity and Secrecy
Characters conceal their true identities and pasts, such as Yeh Ling's hidden history with Trasmere and Ursula's secret background, driving the mystery and revealing how hidden selves shape actions and relationships.
Crime and Justice
The narrative revolves around murder, theft, and detection, exploring the pursuit of justice through Inspector Carver's investigation while questioning the reliability of evidence and the morality of vigilante actions.
Wealth and Power
Jesse Trasmere's immense wealth and control over others, including Yeh Ling and Ursula, illustrate how money corrupts and creates dependencies, while the inheritance plot highlights the allure and danger of financial gain.
Cultural Clash and Orientalism
The contrast between Chinese and Western cultures is depicted through Yeh Ling's dual life, exoticized descriptions, and his philosophical reflections, revealing both fascination and stereotyping in the portrayal of the East.
