Shadowstalker — Larry Patrick Shriner

The story is set in the community of Crescent Key on Florida's Atlantic Coast, home of the very rich and very reclusive. As a favor for a client, Samuel “Loot” Landers, a brooding ex-cop and security expert on the island, goes on the trail of a missing mistress, but nothing is as it seems. As Landers goes on the trail of a killer, danger looms for Landers, as well as the woman he cares so much about. Lives are at stake, and it is winner take all.
