In November 1903, London is gripped by a brutal spree: young, well-born women are found dead with a silk stocking stuffed down their throats, a gruesome motif that unsettles the city and sets Holmes and Watson on a cautious, determined path. Watson, Ian Hart, seeks help from the retired and disenchanted Holmes, Rupert Everett, who quickly determines that the victims are not prostitutes but members of the upper classes, suggesting a motive more personal and deranged than mere crime. The case gathers momentum as Holmes pieces together clues that point away from urban myths and toward a calculated killer with a twisted fixation.
From the crime scene, Holmes collects several telling items: a thumbprint, a pair of ladies’ dancing shoes, broken glass, a strong smell of chloroform, and a silk stocking recovered from one casualty. Each fragment hints at a careful, ritualistic method rather than a random attack, steering the investigation toward someone who would understand or crave such details. The analysis leads Holmes to a chilling conclusion: the killer is not simply violent, but possesses a disturbing foot fetish that informs his choices and staging.
Holmes's interrogation of a survivor—an exceptionally young girl marked by a club foot—reveals a potential suspect, whom he arranges for the girl to “accidentally” observe. This plan hinges on an apparent alibi that seems ironclad; yet, while the girl identifies the suspected captor, the thumbprint on the scene clears him, complicating the trail and hinting at a deeper deception. The detective’s instinct warns that the real danger lies closer than it appears, and the hunt shifts toward outmaneuvering a killer who knows how to cover his tracks.
To bait the killer, Holmes orchestrates a daring theatrical trap: he uses the sister of a victim to perform in a classical tableau at a public event attended by the King and Queen. The Grecian-Roman costume, with sandals that reveal feet, becomes a crucial element in the ruse. After the performance, the sister seeks solitude, and the suspect drugs her, allowing Holmes to seize him as he moves to claim another victim. The sister returns home, where her father tends to her safety and well-being, a brief domestic respite amid the escalating danger.
Yet the trap exposes a troubling twist: the suspect’s thumbprint does not match the evidence, and Holmes suspects that a second killer is at large—an identical twin whose reach extends beyond conventional alibis. A tense telephone warning to the father of the baited sister precedes a cruel reversal, as the real killer abducts the sister from her bed just moments before capture. Viewers witness the horror of the escape as the killer carries her, blood staining her face where glass was broken, deepening the sense that the killer’s cruelty is both intimate and meticulously planned.
The pursuit tightens as police pressure closes in: they compel the surviving twin to reveal the whereabouts of his brother, who remains elusive. In a climactic confrontation, Holmes finds the killer and his captive just in time; the young woman bears a silk stocking tied around her neck, and Watson is forced to cut the binding and perform a dramatic gesture that resembles CPR—an emergency technique with roots stretching back to the late eighteenth century, though not standardized in modern practice until much later. The audacious confession follows: the killer twin pursued attention because he believed his captives would look at him, a cruel incentive that explains the goriness and obsession behind the crimes.
With both twins finally in custody, the case reaches a grim, compelling closure that emphasizes motive as much as method. The twins’ arrest marks the end of the immediate danger, but the investigation’s toll lingers in the memories of those involved. In a final, quieter coda, Watson marries his fiancée Jenny Vandeleur, an American psychoanalyst who aided in the investigation, and the couple leaves for their honeymoon. Holmes remains seated at the table, a solitary figure surrounded by the echoes of a case that tested intellect, nerve, and the fragile boundary between obsession and crime.
