In Cast a Blue Shadow, his fourth Amish mystery, P. L. Gaus spins a suspenseful tale of power, pride, and tested faith. As always, Gaus explores the threshold of culture and faith among the Amish sects and their English neighbors, combining it here with the political divisions unique to the academic world.

After an early winter blizzard in Holmes County, Ohio, a wealthy socialite is found murdered in her mansion. That same morning, a troubled student, Martha Lehman, turns up at her psychiatrist's office, bloody and unable to speak.

Professor Michael Branden and Sheriff Bruce Robertson begin an investigation that threatens to tear Millersburg College apart. Mute for many years as a child, Martha is once again unable (or unwilling) to speak. As Branden wrestles with the murder of the college's leading benefactor, the real story of Martha Lehman begins to emerge--born Amish, converted to Mennonite, and drawn to the "English" world for the worst of reasons.

This new edition of Cast a Blue Shadow features an exclusive interview with the author, reading group materials, and a detailed map and driving guide to Holmes County, Ohio, with everything one needs to visit the iconic scenes depicted in the story.
