Spook
by Bill Pronzini
Shaken after a hair’s-breadth escape from death, Nameless has made changes in his professional life, but he’s not put himself out to pasture. Again he enters San Francisco’s shadowy underworld, this time in a search for the identity of a gentle, mentally disturbed homeless man who has been found dead in an alley doorway. Clues are few, but eventually they bring the Nameless Detective to the small California town that drove the nameless victim tragically to murder and madness.
