Dead Of Winter

Description for DEAD OF WINTER by P J Parrish:

SOME FEARS ARE NEVER LAID TO REST
In the quaint tourist town of Loon Lake, Michigan, a killer is taking his vengeance. One by one, the bodies are found, brutally executed, with mysteriously coded death cards placed beside each corpse--the gruesome signature of a psychopath. And the only sound louder than doors and windows being locked against evil is the sound of hearts beating in terror.

Detective Louis Kincaid had come north looking for a refuge, a place to forget the horrors of his past. But now he s landed in the middle of an investigation that's more than a mystery. It's a warning of bad things to come ... of a terrifying journey through a town's fiercely protected heart of darkness ... and into the nightmare mind of a madman...

This is #2 in Louis Kincaid Series.
