Marlow: Red Tide — Bill Craig

When a dead fisherman is found floating in the waters off of Smather's Beach, the U.S. Coastguard writes it off as an accident. But when his wife is found dead under suspicious circumstances two days later, his sister hires Rick Marlow to look into it. But as Marlow begins his investigation, more bodies begin to drop, and Marlow must find out why before Key West is washed away in a Red Tide of blood!
