A journalist stumbles into a web of lethal obsession, ancient Egyptian curses, and a series of impossible murders orchestrated by a brilliant, vengeful mastermind.
In Short
This novel is a gripping example of early twentieth-century mystery fiction, blending the classic "whodunit" with the exotic, atmospheric dread common to its era. The narrative follows a journalist who finds himself entangled in a vendetta involving a mysterious green cat icon and a series of deadly, high-tech traps. It serves as a quintessential artifact of its time, capturing the period’s fascination with occult threats and the encroaching dangers of modern criminal ingenuity, ensuring its place as a classic of the genre.
The Story
The narrative begins with a discovery that haunts the narrator, an investigative journalist: the body of Sir Marcus, found in a locked stone shed, his face contorted in a terrifying, unnatural green hue. Near the body lies a wooden crate marked with the image of a green cat—a symbol that soon becomes a harbinger of doom for the family of Sir Marcus. The journalist joins forces with Inspector Gatton, a sharp-minded detective who recognizes that the crime is not a simple murder but a calculated act of malice.
As the investigation moves from London to the quiet, eerie village of Upper Crossleys, the conspiracy deepens. The journalist encounters a strange woman who claims to be pursued by "the eyes"—hypnotic, green, glowing eyes that seem to track her every move. Meanwhile, he is targeted by Dr. Damar Greefe, a mysterious figure whose presence is shadowed by the folklore of a "black doctor" and the brutal use of man-traps. The tension rises as the journalist and Gatton realize they are hunting a mastermind who operates with a chilling, clockwork precision, utilizing advanced technology—such as specialized gas devices—to eliminate obstacles.
The mystery takes a dark turn toward the past of the Coverly family. It is revealed that the villainy stems from an old vendetta involving a hidden child, Nahémah, who was cast out by the family. Nahémah, working in tandem with Dr. Greefe, orchestrated the death of Sir Marcus and attempted to frame others, including the innocent Isobel and her companion, Eric Coverly. Eric, trapped by circumstances and his own stubborn pride, refuses to clear his name, ultimately meeting a tragic end when he is mistaken for the journalist in a botched assassination attempt.
The climax arrives when the truth behind the "green cat" is unmasked as an emblem of a vengeful, ancient-inspired curse weaponized by modern science. Through a detailed, written confession, Dr. Greefe explains his orchestration of the murders, revealing the chilling mechanics of the gas-trap telephone that claimed Sir Marcus. The story concludes with the exposure of the conspirators and the unraveling of their complex, blood-stained web. While justice is served, the lingering sense of the uncanny and the tragic destruction of the Coverly line leave a somber impression on all involved.

The People
The narrator is an observant, inquisitive journalist who serves as our eyes on the ground. Driven by a desire for truth and a growing, protective affection for Isobel, he finds himself caught between his objective reporting duties and the very real physical danger posed by his investigation.
Inspector Gatton is the steady, sharp-witted force of law. He is unimpressed by conventional alibis and possesses a "Napoleonic" capacity for logic. He wants to dismantle the mastermind's network, and he views the journalist as a necessary, if sometimes vulnerable, asset in his tactical trap-setting.
Isobel is the emotional center of the story. She is trapped in the center of the unfolding scandal, and her desire to protect those she loves makes her a target. Her strength is tested as she watches the man she cares for, Coverly, succumb to his own pride.
Coverly is a tragic, stubborn figure. He wants to maintain his dignity and independence, but his refusal to cooperate with the authorities or provide an alibi makes him the perfect pawn for the villains. He ends up as a victim of the very game he tried to ignore.
Dr. Damar Greefe is the chilling architect of the plot. He is a man of science and malice, driven by a long-standing, deep-seated vendetta. He views human life as something to be managed by "time-tables" and chemical traps, and he remains calculated and dangerous until the end.
In Its Own Voice
The narrator describes the chilling, inexplicable appearance of the victim in the locked shed:
"On the stretcher, so covered up that only his face was visible, lay one whom at first I failed to recognize, for the horribly contorted features presented a kind of mottled green appearance utterly indescribable."
The narrator recounts the unsettling encounter with the mysterious woman who sought his help:
"Her voice had a totally different tone from that of Isobel--it was a low, almost caressing voice, with a vaguely husky note in it, fascinating in a way, yet although I found myself unable to account for the fact, vaguely uncanny--queer."
The doctor explains the cold, mechanical method used to commit murder:
"In a recess of the room which I caused Sir Marcus Coverly to visit at the Red House, I placed this duplicate telephone; the false cable communicating with the instrument was attached to a plug in the wall above, but communicated with a gas cylinder in the adjoining room."
What It's Really About
The story explores the tension between ancestral curses and the cold, unfeeling application of modern technology. It asks whether the "evil" we fear is a supernatural haunting—the "ginn" or spirits of old—or merely the product of a human mind that has replaced morality with a rigid, detached logic. The book examines the fragility of reputation and truth in the face of a master manipulator, showing how easily the innocent can be consumed by the machinations of the vengeful. It is a meditation on the idea that even in a world of gaslight and science, the ghosts of the past remain capable of wielding lethal power if they are given the right, modern tools.
Why Read It Today
Readers who enjoy the atmosphere of early twentieth-century mystery—the "foggy" London streets, the sense of dread in rural settings, and the methodical, step-by-step unraveling of a crime—will find this book highly rewarding. The pacing is deliberate, favoring a slow-build tension that creates an immersive, slightly claustrophobic world.
One should be prepared for the period attitudes and the occasionally flowery, sometimes repetitive prose style typical of the era’s "popular fiction." The book reflects the anxieties of its time, particularly regarding "Eurasian" villains and "oriental" mysticism, which are presented through a decidedly colonial lens. These dated tropes are part of the historical texture of the work.
What lingers after the final chapter is not just the solution to the mystery, but the feeling of the "green eyes" as a metaphor for the paranoia that can take hold when one feels watched by an unseen enemy. It is a quintessential "late-night" read, best enjoyed when the house is quiet and you are looking for a story that feels both grounded in a recognizable reality and touched by the unsettling, dark corners of a more mysterious past. It remains an effective, if chilling, piece of suspense fiction.
