The Chase of the Golden Plate

In Short

This brisk 1906 mystery introduces Professor Augustus S. F. X. Van Dusen, known as "The Thinking Machine," whose cold, logical deduction solves what the police cannot. When a masked burglar steals gold plate from a society ball, a series of coincidences and an ill-fated elopement plot cast suspicion on a young man named Dick Herbert. As the evidence mounts against him, the story unfolds through a tangle of mistaken identities, secret wounds, and stolen jewels. It remains a classic of the era, celebrated for its snappy dialogue and the unforgettable, irritable persona of its lead detective.

The Story

The chaos begins at a lavish masquerade ball at Seven Oaks. Among the guests, a man dressed as a burglar—a clever ruse that leaves even the hosts confused—steals a collection of gold plate. A young woman, Dollie Meredith, unwittingly mistakes this real criminal for her lover, Dick Herbert, with whom she had planned to elope. She flees the scene with the stranger in an automobile, unknowingly becoming an accomplice to a crime she doesn't understand.

Meanwhile, the real Dick Herbert is absent from the ball, having been waylaid at his home by a mysterious assailant—the genuine "Bill the Burglar," who is actually a man named George Francis Hayden. During a violent confrontation, Hayden shoots Dick in the shoulder and steals a casket of jewels Dollie had entrusted to him earlier that evening. Dick, wounded and disoriented, seeks medical help, unaware that the police are already closing in on him.

Detective Mallory and his team, hampered by their own lack of imagination, interpret the mounting circumstantial evidence—the stolen plate, the missing jewels found in Dick’s possession, and the fresh gunshot wound—as proof of his guilt. Dollie, terrified and confused, is eventually bullied by the police into a confession that places her in the getaway car with Dick, further cementing the case against him.

The narrative shifts to Professor Van Dusen, who approaches the case as a mathematical problem. By examining the nature of the wound, the timeline of the ball, and the history of the characters involved, he methodically tears apart the police theory. He proves that the man in the getaway car was not Dick, but an impostor. Van Dusen eventually reveals that George Francis Hayden, long presumed dead, is the true perpetrator who orchestrated both the ball robbery and the attack on Dick to frame him.

The story concludes with the vindication of Dick Herbert. His reputation is restored, and he secures the blessing of Dollie’s disapproving father. In a final, whimsical twist, the elusive "Bill the Burglar" sends Dollie a solitaire ring as a parting gift, serving as a silent acknowledgement of their bizarre night together. Dick’s instinct to investigate the gift’s origin is cut short by Dollie, who chooses to let the mystery—and the thief—go, opting for a happy ending instead of a new pursuit.

How It Unfolds

A masked confusion The story opens at a high-society masquerade where a genuine criminal, disguised as a burglar, steals gold plate while the guests assume he is merely a performer. Dollie Meredith, planning an elopement, mistakes this criminal for her partner and flees the scene with him in a stolen car.

The web tightens As the police scramble to understand the theft, they discover evidence linking Dick Herbert to the crime. Dick remains isolated, suffering from a gunshot wound inflicted by a mysterious intruder earlier that same night, unaware that his silence is being interpreted as guilt.

The detective’s entry Hutchinson Hatch, a reporter, brings the puzzling facts to Professor Van Dusen, who views the situation as a series of logical variables. The scientist demands specific, strange details—such as blood samples and old class lists—to systematically eliminate impossibilities.

The revelation Van Dusen gathers the key players at police headquarters to expose the truth. He explains that a long-dead fraudster named George Francis Hayden is the true architect of the crimes, having used the elopement plans to frame an innocent man.

The final peace With Dick’s innocence established and the true culprit identified, the case concludes. The story closes on a note of domestic calm, as the couple chooses to leave one final, minor mystery behind rather than pursue it further.

The People

Professor Augustus S. F. X. Van Dusen (The Thinking Machine) is a cold, brilliant scientist who views the world as a series of solvable problems. He is deeply impatient with human error and "impossible" theories, seeking only the inevitable logic of facts.

Dick Herbert is a decent, straightforward man whose love for Dollie leads him into a dangerous trap. He values his integrity but is physically and circumstantially overwhelmed by the machinations of the real burglar, emerging from his ordeal battered but exonerated.

Dollie Meredith is the vibrant, spirited daughter of a rigid man. Her impulsiveness and devotion to Dick drive the plot, and though she is manipulated by the police and the true thief, she maintains a sense of agency, eventually choosing her own happiness over the pursuit of justice.

George Francis Hayden (Bill the Burglar) is the cunning, unseen antagonist. He is a master of fraud who thrives on chaos, using his knowledge of the characters’ personal lives to orchestrate a crime that nearly ruins two lives.

In Its Own Voice

"Nothing is impossible, Mr. Hatch," snapped The Thinking Machine irritably.

The professor rebukes the reporter for doubting the accessibility of the truth.

"I have come to explain why I did not meet you at the Randolph masked ball, as we had planned."

Dick finally speaks to Dollie after the misunderstanding has nearly destroyed their future.

"You dear old thing!" she gurgled. "You're just too sweet and cute for anything."

Dollie expresses her gratitude to the socially awkward, annoyed scientist after he secures Dick’s freedom.

What It's Really About

The central argument is that the human mind, when disciplined by pure logic, can penetrate any deception. The book posits that mystery is not a product of chance, but a failure of observation. Beneath the surface of a simple robbery, the story explores the tension between romantic impulse and rigid, scientific calculation. It suggests that while people may act on emotion—like Dollie’s devotion or Mr. Meredith’s stubbornness—the objective truth remains unmoved by these feelings. Ultimately, the book asserts that justice is not a matter of intuition or moral posturing, but a cold, deductive process that must be pursued until the facts align like numbers in an equation.

Why Read It Today

This book is a delightful artifact for those who enjoy the intellectual puzzles of classic detective fiction. Readers who appreciate Sherlock Holmes will find a kindred spirit in the insufferable yet brilliant "Thinking Machine." The prose is lean and moves with the urgency of a newspaper serial, capturing a specific, romanticized version of American society at the turn of the century.

You will find the book’s greatest charm in the contrast between the high-strung, emotional lives of the young lovers and the icy, detached intellect of the professor. It is a quick read, feeling much like a well-structured stage play.

However, modern readers should be prepared for the period-typical portrayal of women as essentially emotional creatures whose actions are often driven by "perfidious" or "dainty" whims, as described by the narrator. Additionally, the plot relies heavily on coincidences—such as the "little brother with a pain in his tummy" determining the timeline—which might feel strained to those used to tighter contemporary thrillers. If you can set aside these dated tropes, you will be rewarded with a clever, briskly told mystery that values wit over grit. It leaves the reader with a satisfying sense of order restored, tempered by the lingering, playful mystery of the final ring.
