🎭 Directed Edition — every role cast for this story and every line performed with full voice direction.

On the last Monday of December 1957, a woman in a travelling coat climbs the stairs at Baker Street. Rosamund Ferris has flown through the night from New York, leaving her son Maddox unburied at his house in Cedar Cove, Long Island. He was shot dead in the upstairs hall by his wife, Lorna, who says she fired at a prowler she had feared for months. Holmes calls it grief and refuses to cross an ocean for a cold trail, until Watson reminds him what the journey has cost her. At the house, the shutters are drawn against a crowd of newsmen, and the sleepless widow, in black, tells the detectives to look wherever they like. Upstairs, an inspector of the county police reads out her signed statement: a noise on the roof, a shotgun by the bed, a tall figure in the dark hall, both barrels. Holmes notes where the shot struck the doorframe. Across the yard, the family chauffeur, dismissed after twenty years by a note left on the car seat, is packing his trunk and says he will not wear black for his employer. Holmes has taken the case, but what exactly is he meant to find?

From the series Sherlock Holmes — The New Cases: a real crime of the 1950s reimagined as a classic Sherlock Holmes radio mystery, performed by a full multi-voice AI cast, with sound design and a light score that stays under the story.

Loosely inspired by a real event of the 1950s. All names, characters, dialogue and events are fictional; the words, actions, motives and private lives of every character — including the wealthy family, their household staff, the villagers, the investigators and the police — are invented for drama, and so is the solution of the mystery. Where a real city, state, public body or newspaper is mentioned, its part in this story is invented; the village, the estate and its telephone exchange named in it are invented too. This is a work of fiction, not a factual account of any real person or institution. No real person is portrayed, and no real individual, company or organisation is accused of any act shown here.

Setting: London and Cedar Cove, Long Island — December 1957.

Writer v2.7 — the studio's newest writing process: the plot is planned and checked by an AI story editor, then each act is drafted with the whole story in view and edited before a word is voiced — and then cast and performed with our new casting and voice direction.
