When a spiritual medium is murdered in a locked hut on a haunted estate, Sir Henry Merrivale seeks a logical solution to a ghostly crime. Plague Court is old and crumbling, long neglected after its lord, hangman's assistant Louis Playge, fell victim to the black death hundreds of years before. Famously haunted by Playge's ghost, the property finally has a new owner and banishing the spirit is the first order of business.

And when the medium employed with this task is found stabbed to death in a locked stone hut on the grounds, surrounded by an untouched circle of mud, the other guests at Plague Court have every reason to fear an act of supernatural violence—for who among them would be diabolical and calculating enough to orchestrate such an impossible execution?

At a costume party with the dubious theme of ‘famous murderers and their victims’, the know-it-all amateur criminologist Roger Sheringham is settled in for an evening of beer, small talk and analysing his companions. One guest in particular has caught his attention for her theatrics, and his theory that she might have several enemies among the partygoers proves true when she is found hanging from the ‘decorative’ gallows on the roof terrace.

Noticing a key detail which could implicate a friend in the crime, Sheringham decides to meddle with the scene and unwittingly casts himself into jeopardy as the uncommonly thorough police investigation circles closer and closer to the truth.
