Review title: existential insight into a troubled mind
Product review: Loved the three books contained in this volume. Engrossing stories about a man with a troubled mind who lives a very pleasant and noremal life, ... except for a few excursions into murder. The hero is the villan, an unusual twist to the thriller mystery novel.
