Show of evil - William Diehl

When Linda Balfour, a young mother, is found butchered in small-town southern Illinois, a coded inscription stamped in blood on the back of her head brands her mutilated body.
For Chief Prosecutor Martin Vail, the Bloody insignia drags up memories he'd like to forget - memories of Bishop Rushman, slashed and dismembered ten years ago by an altar boy, Aaron Stampler.
But if Stampler is locked away, he cannot have murdered Linda.
With his career - and his life - on the line, Vail needs answers fast before the killer signs someone else's life away.
