Murder Comes by Mail by A. H. Gabhart focuses on Deputy Sheriff Michael Keane. Towards the beginning of the story, Keane saves a suicidal man. But when Keane receives photos of a murdered girl in the mail, he is convinced that he knows who the killer is: he may be the very man he saved.

I liked how Keane had admirable virtues and a protective nature. I also liked how Keane was introspective, and that readers were able to get inside his head. The dialogue flowed naturally, and the plot moved at a steady pace. The eeriness of the story gave it a good dose of suspense.
