The Rat Racket

In Short

This story follows an immensely wealthy and eccentric man who decides to dismantle the racketeers terrorizing New York City by exploiting their own methods. When a criminal syndicate begins using swarms of rats to extort business owners, the protagonist, Winifred Willowby, treats the problem as a grand, scientific, and political experiment. By combining historical folklore with advanced technology, he orchestrates a final confrontation that leaves the criminal underworld decimated. It remains a fascinating relic of early pulp science fiction, blending urban anxiety with the surreal precision of a dark, calculated revenge fantasy.

The Story

The narrative begins with Moyer and Perkins, two grocers struggling under the thumb of a brutal racketeering syndicate. The gang’s signature tactic is "rat protection": they force businesses to pay exorbitant fees by threatening to unleash massive, destructive swarms of rats into their warehouses. The local Chamber of Commerce, paralyzed by fear and lack of understanding, offers no help. As the racket spreads to hotels and threatens the city’s economy, the racketeers’ power grows, eventually reaching the ears of Winifred Willowby, the richest man in New York.

Willowby, a man of intense, quiet focus, approaches Moyer and Perkins with a proposition: he will buy their business, provide them with a fortune, and handle the "rat problem" himself. He recruits a team of experts—a biologist, a psychologist, and an antiquarian—to study the behavior of rats, specifically looking into the legend of the Pied Piper of Hamelin. Willowby becomes convinced that if a specific, hypnotic frequency or tune can attract rats, it can be used to control them.

While the scientists conduct experiments in various properties Willowby has purchased, the racketeers continue to expand, eventually controlling the city’s infrastructure and aiming for national political influence. Willowby realizes that the only way to stop the "Old Man," the shadowy kingpin of the racketeers, is to neutralize the entire leadership of the syndicate at once. He orchestrates a secret meeting at his private office in the Empire Trust Building, under the guise of an alliance to launch his own bid for the presidency.

The meeting brings together one hundred of the most powerful gangsters in America. Once they are assembled, Willowby orchestrates a trap. He has installed a phonograph system throughout the building designed to play the "rat-attracting" tune he acquired from his research into the Piper of Hamelin. As the music plays, millions of rats emerge from the building’s infrastructure, swarming the assembly room. The ensuing slaughter is absolute. The gangsters are killed by the rodents, and the Old Man, realizing his end has come, chooses to leap to his death from a window rather than face the swarm. Willowby later presents the aftermath to the authorities as a tragic accident—a "rat infestation"—and emerges as the savior of a country suddenly freed from its criminal masters.

How It Unfolds

The protection racket Moyer and Perkins receive a chilling letter demanding payment for protection against a rat menace. They quickly discover that the racketeers' threats are not hollow, as businesses that refuse to pay are systematically destroyed by rodent swarms.

The millionaire's entry Winifred Willowby appears, purchasing the victims' businesses to create a laboratory for studying rat behavior. He rejects the traditional, panicked responses of the authorities, instead choosing to treat the infestation as a problem to be solved with science and research.

Consulting the experts Willowby gathers a biologist, a psychologist, and an antiquarian to investigate the mechanics of mass rat movements. They discuss the historical legend of the Pied Piper, theorizing that musical vibrations might influence the rodents' nervous systems.

The trap is set Willowby lures the top one hundred gangsters to his penthouse office by promising a partnership to seize control of the federal government. He ensures the building is prepared to broadcast the specific frequency that drives rats into a frenzy.

The final reckoning As the gangsters drink and wait for their payoff, the music begins and the rats emerge in overwhelming numbers. The room is transformed into a slaughterhouse, effectively ending the reign of the criminal syndicate in a single, horrific night.

The People

Winifred Willowby is the story's calm, diminutive architect of justice. Possessing a fortune that dwarfs the influence of the state, he views the racketeers not just as criminals, but as an affront to his vision of a "100 per cent American" city. He is cold, calculating, and ultimately ruthless.

The Old Man (Consuelo) is the antagonist, a titan of crime who rules through fear and force. He is portrayed as an ape-like, brutal figure who believes he can outmaneuver anyone. He eventually realizes his mistake when he finds himself trapped in Willowby’s office, choosing a final, defiant act of suicide over the ignominy of being devoured.

Moyer and Perkins are the relatable, honest businessmen caught in the middle. They represent the collateral damage of the racketeering era, wanting only to escape the danger. Unlike Willowby, they have no stomach for the "field of battle" and eventually retreat to England.

Rastell, Wilson, and Crawford serve as the scientific curiosity of the piece. They provide the intellectual framework for the story’s central conceit, treating the rats as a puzzle to be solved through biology and folklore rather than the crude bombs and threats used by the gangsters.

In Its Own Voice

"You could show that letter to a hundred police officials and they would laugh at your fears."

This is Perkins describing the hopelessness of the business owners who are being targeted by the invisible, systematic extortion of the rat racketeers.

"The rats came--and killed them."

Willowby offers this chilling, overly simplistic explanation to the Chief of the Secret Service after the carnage in his office has concluded.

What It's Really About

The book is a dark exploration of power, order, and the fragility of a society under siege. It posits that when established institutions—like the police or the Chamber of Commerce—are too cowardly to confront organized crime, the state becomes vulnerable to those willing to play the game by more extreme rules. Willowby represents a "benevolent" dictator who believes the end justifies the means; he cleans the city of corruption, but only by employing a violence just as systematic and terrifying as the criminals he destroys. It raises the question of whether a society is truly "saved" when its liberation is bought through the cold, calculated manipulation of nature and death.

Why Read It Today

Readers who enjoy the brisk, hard-boiled pacing of 1930s pulp fiction will find this a compelling artifact of the genre. Its appeal lies in its "what-if" premise: the idea of a criminal empire so sophisticated it uses biological terror to control an entire metropolis. The writing is direct and devoid of sentimentality, reflecting the era’s fascination with the "big men" of industry and the shadows of the urban landscape.

However, the reader should be prepared for the story’s bluntness. It is a product of its time, featuring period-typical attitudes toward "foreign" criminal elements and a casual, almost detached treatment of extreme violence. The dialogue is functional rather than literary, and the plot moves with a frantic, sometimes jarring speed that prioritizes the "ingenious solution" over deep character development. It is not a subtle book; it is a bizarre, dark, and highly focused thriller that turns the myth of the Pied Piper into a tool of modern urban vengeance. If you are interested in the evolution of crime fiction and the strange, imaginative leaps of early speculative writing, it offers a haunting and memorable experience.
