Fury on Sunday

In the early hours of a Sunday morning, lunatic pianist Vincent Radin escapes from an insane asylum and sets out on a revenge-fueled rampage. His aim is to find the two people who have hurt him most—his erstwhile manager and his lover’s new husband—and end their lives.
The second of Richard Matheson’s published novels, this book demonstrates the skill in pacing, plot, and suspense that characterize his later work. This lurid thriller tells the story of a man who will stop at nothing to enact his revenge—and the people who get caught in the crossfire—in spare, relentless prose that’s impossible to put down.
