The hollow lens

In Short

This brisk crime caper follows Chester Fay, a professional "peterman" hiding out in California, who is recruited by a woman claiming to be the daughter of a jailed associate. Her target is "The Black Cougar," a predatory broker who has swindled thousands from within the law. As the pair executes an elaborate, technically inventive break-in, the story shifts from a standard heist into a clever narrative of double-crosses and technological intrigue. It has endured as a sharp example of early 20th-century pulp fiction, capturing the specific vernacular and fast-paced tension of the era’s underworld literature.

The Story

Chester Fay, a refined criminal living under an alias in the quiet golf community of Short Hills, is approached by a woman named Saidee Isaacs. She claims to be the daughter of "Big Scar" Charlie Laurie, a notorious safe-cracker currently serving a long sentence. Saidee proposes that they team up to rob Frank Robertson Pope—a ruthless bucket-shop operator known as "The Black Cougar"—who has built a fortune by ruining widows and commoners alike. Though wary, Fay is swayed by the prospect of stealing from a man he considers a "disgrace to all the good crooks in the world."

The pair concocts a plan to gain access to the vault in Pope’s office by taking over a photograph studio located directly above it. Saidee poses as a photographer, while Fay, using his specialized knowledge, prepares to breach the vault’s vanadium steel layers. The heist is unconventional; rather than using explosives or drills, Fay constructs a "hollow lens"—a massive water-filled glass device—to focus the intense California sun into a beam of extreme heat, melting through the vault’s plates with clinical precision.

Throughout the process, the two observe Pope from a hidden peephole. They watch him handle mysterious spools of iron wire that he keeps locked in the vault, a detail that puzzles Fay. Despite the mounting tension and the constant presence of a night-watchman, they successfully penetrate the vault and secure $37,000 in cash.

After the theft, the dynamic between the two shifts abruptly. Saidee reveals that she is not the daughter of a criminal at all, but an operative for the Secret Service. Her true objective was not the cash, but the "sucker-list"—a database of thousands of potential victims that Pope had encoded onto the iron wire spools using a method akin to magnetic telegraphy. She had used Fay to gain access to the vault because the authorities could not legally seize the list through conventional means. Fay, having been outplayed, is nonetheless allowed to keep the cash as his reward for the "professional services" of cracking the box. The story concludes with the two parting ways: Saidee returns to the government with the evidence that will dismantle Pope’s empire, and Fay, realizing he has been "the dub" in a much larger game, escapes to the East, left with both his freedom and a newfound respect for his clever adversary.

How It Unfolds

The encounter on the links Fay is approached at his golf club by a woman who reveals an intimate knowledge of his criminal past. She offers him a lucrative, risky partnership targeting a man they both despise.

The setup The pair establishes a cover in the Bradock Building, pretending to run a photography studio to mask their work. Fay performs meticulous reconnaissance, including drafting building plans and observing the target's habits through a hidden floor panel.

The technological strike Fay constructs a makeshift solar-lens device to bypass the vault’s heavy steel protection without using noisy or traditional explosive methods. As he burns through the layers of the vault, he remains suspicious of the strange wire spools Pope protects so fiercely.

The breach Working through the weekend, Fay successfully cuts into the vault and retrieves the contents. The theft is completed, but the expected massive fortune is smaller than anticipated, leading to a tense realization.

The reveal Saidee discards her disguise, revealing her status as a government agent. She explains that the true goal was the magnetically encoded wire, which the government can now use to warn the victims and ruin Pope.

The final parting The heist concludes with a professional, almost respectful, parting between the criminal and the agent. Fay realizes he was a pawn in a larger, legal scheme, but chooses to accept the outcome and leave town.

The People

Chester Fay is a sophisticated, graying safecracker who prides himself on his professionalism and his code of ethics. He wants to rob "The Black Cougar" to satisfy his own moral compass, believing that stealing from a predator is a form of justice. By the end, he is humbled, realizing that his own cunning was surpassed by the woman he thought he was leading.

Saidee Isaacs is the driving force of the story. Cool, calculating, and exceptionally observant, she uses the persona of a "gun-moll" to manipulate Fay. Her primary goal is the destruction of Frank Robertson Pope’s business through the recovery of his secret "sucker-list." She ends the story in total control, having achieved her mission without ever needing to arrest her unwitting accomplice.

Frank Robertson Pope, or "The Black Cougar," is the antagonist. He is a bucket-shop broker who exploits the letter of the law to ruin others. He is portrayed as a hypocrite who guards his wealth and his trade secrets—the magnetically encoded wire—with intense paranoia. He ends the story defeated by his own secret methods, as the government uses the information he tried so hard to hide to dismantle his operations.

In Its Own Voice

“In the argot of the underworld, Chester Fay, alias Edward Letchmere, an expert on other people’s strong-boxes, had lammistered to Short Hills, California, where an excellent golf-links surrounds a half-hotel, half-clubhouse of the superior order.”

The story opens by establishing Fay’s refined but illicit background, contrasting his criminal history with the quiet, leisure-filled setting where he hides.

“The girl who now professed to be his daughter resembled him in no particular.”

Fay immediately notes the discrepancy in the appearance of the woman claiming to be the child of the rough-hewn "Big Scar" Charlie Laurie.

“I’m a dub,” he admitted. “I’ll let you put it all over me.”

Fay concedes his defeat to Saidee at the end, acknowledging that his pride in his own cleverness was eclipsed by her superior strategy.

What It's Really About

At its heart, the book explores the thin, often blurred line between the "professional" criminal and the "legitimate" predator. Fay perceives himself as an outsider with a moral code, choosing his targets carefully to punish those who exploit the weak. The story argues that the truly dangerous figures are not the bank-robbers, but those like "The Black Cougar" who operate within the law to facilitate large-scale theft. The central irony is that the law must break its own conventions—using a criminal to commit a burglary—to achieve justice against a man who is legally untouchable. The narrative asks whether morality is defined by one's legal status or by one's actions, and it suggests that being "outside the law" is sometimes the only way to hold those "within the law" accountable.

Why Read It Today

Readers who enjoy the brisk, hard-boiled tone of 1920s pulp magazines will find this a satisfying, tight experience. It moves with a singular focus, wasting no time on unnecessary character backstories, and the central conceit—a solar-powered safe-cracking machine—is a delight of mechanical imagination. It feels distinctly like a piece of its era, with its specific slang and the casual, often cynical worldview of its characters.

The book is not without its challenges; the dialogue is heavily stylized with period-specific "underworld" jargon that may take a moment to decode, and the gender dynamics reflect the attitudes of the early 20th century. However, the rapport between the two leads is sharp and fast, and the reversal of the typical "heist" trajectory—where the thief is actually helping the state—keeps the momentum high. If you enjoy stories where the protagonist is outsmarted by a sharper, more prepared opponent, and you appreciate a well-plotted, self-contained mystery that reaches a definitive, clever conclusion, this short tale is a rewarding visit to a bygone era of crime fiction. It leaves the reader with a sense of the quiet, dusty California landscape and the satisfaction of a grift perfectly executed.
