Edition details
Book Summary
A mysterious cask shipped from Paris to London contains a murdered woman's body and gold sovereigns. Inspector Burnley and private detective La Touche pursue a complex investigation across England and France, ultimately exposing a jealous husband's elaborate plot to frame an innocent man.
The story begins when a damaged cask is discovered aboard the SS Bullfinch, revealing a woman's hand among gold coins. Inspector Burnley investigates, tracking the cask to a man named Felix, who claims it was sent by a Parisian friend. Despite Felix's detailed story, Burnley arrests him after finding the body inside. In Paris, defense lawyer Clifford hires detective La Touche to investigate the victim's husband, M. Boirac. La Touche meticulously dismantles Boirac's alibi, discovering he replaced a typewriter used to forge incriminating letters and bribed a carter to deliver the cask. Boirac confesses to murdering his wife Annette out of jealousy over her past relationship with Felix, then escapes, attempts suicide, and dies. Felix is exonerated and finds happiness marrying Heppenstall's daughter.

Narrative arc
Story tension across the book.
- Setup
Mr. Georges La Touche
La Touche works the margins of the investigation, paying porters for descriptions and staking his dwindling funds on hunches the official police overlook. His restless night produces the insight that the reward notices have been aimed at the wrong man entirely, and he drafts a circular under a false name to reach the carter's employers. His willingness to spend and dissemble for an accused man's sake makes him the story's quiet engine of alternative inquiry.
Mr. Felix
Felix is the consignee whose name is stencilled on the cask, a designer with a housekeeper conveniently away on holiday when the body travelled. He produces envelopes to prove his identity, signs for the shipment, and disappears for twenty-two hours that the police cannot account for. Whether he is a grieving man, a fugitive, or something stranger, his absence shapes every question the detectives ask in the early and middle chapters.
M. Boirac
Boirac sits at the centre of the case's most obvious motive: a husband who may or may not have known his wife was leaving him for another man. The discovery of a matching cask unpacked in his study briefly hardens suspicion, then dissolves into an explanation that leaves the Chief doubting again. His love, or lack of it, for Annette becomes the pivot on which the whole theory of the crime turns.
M. Lefarge
Lefarge is the steady, methodical half of the investigative pair, the one who remembers that the cask's weight was extraordinary and that the carter's description might be worth fifty francs. He is not afraid to challenge the Chief's narrowing focus, suggesting that someone entirely outside the Felix-Boirac triangle may be responsible. His patient reconstruction of the cask's movements gives the middle chapters their spine.
Inspector Burnley
Burnley is the official mind of the case, cautious with his suspicions and careful with his evidence, refusing to commit himself even to Felix on the walk to the Yard. He supervises the unpacking himself, sifting sawdust through his fingers until the sovereigns give way to something far worse. His disciplined, almost reticent method contrasts with La Touche's gambits and sets the tone for the investigation's slow, granular progress.
Annette Boirac
Annette is known to the reader first as a dress sold in February, then as a name on a hotel register, and only gradually as a woman with a life the detectives must reconstruct from fragments. Her marriage to Boirac, her connection to Felix, and the question of whether she left willingly or was taken become the case's central ambiguity. She never speaks in the passages, yet her choices — or the choices attributed to her — determine who is suspected and why.
Deception and Appearance
The entire plot revolves around false identities, forged letters, mislabeled casks, and disguised vehicles, showing how characters manipulate appearances to deceive others and evade detection.
Crime and Investigation
The book follows a detailed police investigation into a murder, highlighting the methods of detectives, the gathering of clues, and the process of building a case across multiple countries.
Love and Jealousy
The murder is motivated by past romantic entanglements and jealousy, as Felix's former love for Annette Boirac and her marriage to Boirac create a triangle of passion and resentment.
Class and Social Status
Social standing influences characters' actions and opportunities, from Felix's rejection by Annette's father due to his lower status, to the reliance on working-class witnesses like carters and dockworkers.
