The Leper of Saint Giles is a medieval mystery novel by Ellis Peters, set in October 1139. It is the fifth novel in The Cadfael Chronicles and was first published in 1981. The book includes a map of the Abbey, the town of Shrewsbury, St. Giles, the winding River Severn and its small local brooks, and places in the environs mentioned in this story and others in the series. It was adapted for television in 1994 by Central for ITV. Two landed families arrange a marriage between an older baron and a young woman who loves someone else. The groom does not arrive at the altar. It falls to Cadfael to find his murderer, while the main suspect of the sheriff hides in the house for lepers. This novel was ranked number 42 in the 1990 list of The Top 100 Crime Novels of All Time by the British Crime Writers Association. Citing the public confrontation and the main character's skills at deduction, one reviewer said it was "another Peters delight, featuring vital characters, a beautifully organised puzzle, and history made real." Another reviewer felt that "predictable plotting is amply compensated for by the author's wonderful re-creation of the period". Source: Wikipedia (en)
