Zack Walker Mystery# 3

Journalist, family man, and paranoid writer Zack Walker visits his father's lakeside fishing camp. But the fresh air, childhood memories and peaceful contemplation are ruined when a body is found.

Locals say the mutilated corpse must have been the victim of a random bear attack. But Zack Walker, as always, fears the worst.

When another body is discovered, it seems there is a more deadly predator on the prowl. A Lone Wolf killer who is hell-bent on laying siege to the idyllic town.

The fuse is lit and time is running out. Zack must face down a madman - or find out first-hand what the grand finale is . . .
