A dead woman in a bachelor's flat, a stolen identity, and a trail of poisonous serpents lead an innocent man across Europe in search of the truth.
In Short
When Teddy Royle finds a murdered woman inside his best friend's locked apartment, his search for answers plunges him into a shadowy web of deceit. The real Sir Digby Kemsley is missing, an clever impostor has taken his place, and Teddy's own fiancée, Phrida, seems entangled in the conspiracy. Hunted by international criminals and eyed with suspicion by Scotland Yard, Royle must unravel a plot involving Peruvian snakes, stolen legal documents, and black-market intrigue. First published in 1917, this classic Edwardian thriller endures for its relentless pace, dramatic twists, and atmospheric depiction of mystery-era London and Brussels.
The Story
The mystery opens in London when Teddy Royle receives an urgent telephone message summoning him to the flat of his wealthy friend, Sir Digby Kemsley. Upon arrival, Teddy discovers a startling scene: the man claiming to be Digby is an unfamiliar figure with a crafty manner and uneven shoulders who insists he is the real baronet. Shortly after this bizarre meeting, a young woman is found brutally stabbed to death inside the flat with a distinctive triangular dagger bearing the Medici crest. To make matters worse, the mysterious substitute vanishes into thin air, leaving Inspector Edwards of Scotland Yard to suspect that the real Sir Digby was either an assassin or an impostor who died months earlier in South America.
Determined to clear his friend's name, Teddy begins his own investigation. His anxiety turns to horror when forensic evidence links the crime scene to his beloved fiancée, Phrida Shand. Fingerprints on a glass specimen table match Phrida's, and she breaks down in terror whenever questioned about the night of the murder. Although she vehemently denies killing the woman—identified tentatively as Marie Bracq—she refuses to reveal what she knows, claiming that speaking out will mean her immediate doom. Meanwhile, Digby appears briefly to Teddy disguised as a clergyman, warning him to keep silent and follow a series of cryptic instructions.
Teddy's search for answers brings him into the orbit of Mrs. Petre, a ruthless woman who harbors a deep hatred for Digby. When Teddy confronts her, she traps him alongside a Hindu snake charmer and an Indian named Ali. They drug Teddy and subject him to a terrifying ordeal with a hooded, venomous serpent intended to silence him permanently. Though he narrowly survives the trap, Teddy realizes he is up against an organized criminal syndicate operating across borders.
Following a trail of secret correspondence, Teddy travels to Brussels with Inspector Frémy of the Belgian police. There, they track down the mysterious "Mr. Bryant" collecting mail at the Poste Restante. The investigation culminates in a dramatic showdown at a private residence. Accompanied by Senos, a loyal Peruvian native, the police confront the villain: Herbert Cane, the man who had been impersonating Sir Digby.
Senos reveals the full truth behind the intrigue. Cane had murdered the real Sir Digby Kemsley in Peru using a poisonous snake to steal a valuable concession document worth a quarter of a million francs. He then traveled to England under Digby's name, accompanied by his accomplice Mrs. Petre. The murdered girl in London was actually a royal princess who had discovered Cane's true identity and threatened to expose his theft. Cane killed her and manipulated Phrida into believing she was responsible for the death, ensuring her silence. Cornered by the police and facing extradition, Cane defiant to the last, meets his end, completely exonerating both Phrida and the late, genuine Sir Digby Kemsley.

In Its Own Voice
"I tell you that my name is Kemsley--Sir Digby Kemsley."
An impostor brazenly asserts his stolen identity to a stunned Teddy Royle inside the missing baronet's flat.
"You know that woman--you can't deny knowledge of her--can you?"
Teddy confronts Phrida after discovering her connection to the mysterious Mrs. Petre and the murder scene.
"The music, now being played incessantly, apparently prevented the snake from darting at me, as it was, no doubt, under the hypnotic influence of its master."
Teddy reflects in horror as he lies paralyzed, watching a deadly cobra sway inches from his face.
What It's Really About
Beneath its energetic mystery plot, the novel explores the fragility of identity and the ease with which a man's name can be stolen and corrupted. It contrasts genuine personal loyalty against deceptive appearances, forcing Teddy to choose between blind trust in his loved ones and the cold, hard facts uncovered by forensics. The story touches on Edwardian anxieties regarding international crime networks, exotic overseas poisons, and the dark underbelly lurking just beneath the polished surface of Mayfair society. Ultimately, it poses fundamental questions about justice: whether legal institutions can uncover the truth without the help of devoted friends, and how far an innocent person ought to go to shield those they love from ruin.
Why Read It Today
Fans of traditional Edwardian mystery fiction and classic locked-room puzzles will find plenty to enjoy in this fast-paced thriller. William Le Queux crafts a story filled with quintessential period atmosphere, sweeping the reader from fog-draped London streets to continental post offices and luxurious Belgian dining rooms. The narrative moves at a rapid clip, relying on dramatic twists, secret ciphers, and high-stakes confrontations rather than lengthy technical deductions.
Modern readers should be prepared for typical period conventions, including melodramatic dialogue, somewhat passive heroines, and sensationalized depictions of foreign cultures—such as the exoticized use of snake-charming as a murder weapon. Additionally, the plot relies heavily on coincidences and sudden admissions to push the investigation forward. However, if you enjoy classic sensation novels where duty, romance, and murder collide, this story delivers an entertaining journey into early 20th-century popular fiction.
