The Lirey Shroud Mystery

Collette Dubois, the wife of the Bailli of Troyes, is discovered plunging a dagger into the chest of man who had attacked her several weeks earlier. She escapes, leaving her husband (Henri) and his deputy (Jean Bellimont) to unravel the web of intrigue which led up to this event. The two men become convinced of her innocence, and are eventually led to a mysterious artefact which the murdered man had been commissioned to produce for a local noble. The Bishop of Troyes is also implicated, and Henri must balance his personal interest in the case against the involvement of two of the town's most influential citizens. The investigators are presented with a bewildering array of suspects and motives, before the pieces finally fall into place and the puzzle is solved.
This is the fourth of the Jean Bellimont novels.
