Let's set the scene: London in the late 1920s. A young box office clerk is found dead, an apparent suicide. Then another dies in a questionable accident. When a third meets a grim fate, Scotland Yard's Inspector Joseph French decides there's a pattern here that stinks to high heaven. These women, all cashiers handling nightly ticket receipts, are connected by more than their jobs. They've all been dabbling in what seems like a lucky streak of successful stock market tips, funneling their cinema's cash into a shadowy investment pool. French's investigation becomes a meticulous chase, not for a bloody knife or a smoking gun, but for a paper trail—ledgers, bank drafts, and forged identities.

The Story

The heart of the story is French's dogged, step-by-step police work. He follows the money from the London box offices to a central agent, and then into the hands of a ruthless criminal mastermind. The killer's scheme is chillingly methodical: befriend the women, promise them easy wealth, use their positions to embezzle funds, and then silence them permanently to cover the theft. The tension doesn't come from car chases (this is 1929!), but from the quiet dread of French racing to identify the criminal before the next girl on the list is murdered. The finale is a satisfyingly logical unraveling, where every clue French painstakingly gathered clicks into place.

Why You Should Read It

If you think classic mysteries are all about drawing-room accusations and intuitive genius detectives, Crofts will change your mind. Inspector French is the anti-Holmes. His genius is pure, relentless procedure. You get to solve the case with him, examining timetables, bank records, and alibis. It’s incredibly rewarding. The book also has a sneaky social conscience. It shines a light on the lives of these young, working-class women, vulnerable to promises of a better life, which gives the crime a real emotional weight beyond the puzzle.

Final Verdict

This book is perfect for puzzle purists and fans of police procedurals who enjoy the 'how' as much as the 'who.' If you love the methodical detail in modern shows like Line of Duty or the classic Law & Order 'ripped-from-the-headlines' feel, you'll find a kindred spirit in Crofts. It's also a fantastic pick for anyone curious about the roots of the detective novel. It’s a masterclass in fair-play plotting where the author shows you all the pieces—the challenge is seeing how they fit together before French does.
