Two separate murders and a poisoning spark a multi‐layered investigation that unfolds through interconnected scenes at a clinical study, victims’ homes, and police headquarters. An over‐worked doctor discovers a dying youth whose puzzling final words hint at a botched pistol shooting and an absent murder weapon. The subsequent discovery of a dead maid in a neighboring house complicates the scene. As doubts mount over whether the deaths are murders, suicides, or accidents, the police and medical experts begin to reconstruct a sequence of events involving disturbed domestic relationships, clandestine financial dealings, and unorthodox use of poison. The investigation focuses on a toxic substance—hyoscine—found in unusually high concentrations in the female victim, suggesting deliberate poisoning. Meanwhile, forensic examinations reveal that the young man, who died from gunshot wounds to his lung, shows no trace of the poison. The scene is littered with clues: a broken window indicating forced entry, a stray cigarette‐holder containing an amber‐encased fly that was crafted by an in-house mechanic for a local chemist, and inconsistent arithmetic in the victim’s laboratory notebook hinting at careless record‐keeping. A cipher message—seemingly assembled under the signature “Justice”—also appears, ultimately decoded to read as a question about who had access to the poisonous hyoscine at the nearby research institute. Detectives debate a range of nine theoretical scenarios for the dual deaths, from mutual murder to combined suicide, but further evidence leads them to eliminate possibilities involving accidental shooting or simultaneous suicide. Testimonies from acquaintances and domestic staff reveal a volatile love triangle and financial tension. One woman, previously engaged to the deceased, bitterly recalls how the victim was lured away by another woman, whose influence appears central to the unfolding tragedy. Meanwhile, financial records trace the victim’s mounting debts and an insurance scheme benefiting an unscrupulous moneylender, hinting at a potential motive for murder for profit. As the police coordinate forensic tests, including a mixed melting‐point analysis for the hyoscine levels, they also pursue leads from external sources—a mysterious telegram and an informant known as “Justice,” as well as a low-level criminal with ties to motor accidents in dense fog. Interrogations with colleagues at the research institute further confirm that the poison was accessible only to a restricted group. Fractured diary entries of the deceased hint at burgeoning remorse and a plot for revenge prompted by personal betrayal. The investigation teeters between scientific evidence and human frailty as officials piece together clues while debating whether the crimes were the calculated work of an outsider manipulating domestic strife or a set of impulsive acts stemming from deep-seated personal rancor. Ultimately, the case becomes a tangle of forensic puzzles, cryptic communications, and conflicting accounts—each possibility more untenable than the last—forcing the investigators to narrow down the suspects to a small circle of trusted insiders and prompting them to question who truly had access to the lethal hyoscine at the institute.

Dr. Ringwood pushed his chair back from the dinner-table. A glance at the clock on the mantelpiece told him that on this evening he had been even later than usual in getting home for dinner. The expression in his eyes showed that he had gone short of sleep for some time past; and when he rose to his feet, every movement betrayed his overtired condition.
"Bring my coffee to the study, please, Shenstone," he ordered. "And you might take the telephone in there as well."
