The Big Kiss-Off — Day Keene

CADE had come home to the Gulf country to find murder waiting, and queer terror. For no reason he could fathom, brutal enemies were trying to destroy him. Even his wife, the lovely Janice, joined the campaign to kiss off Cade somehow -- hurt him, maim him, kill him!

Why? What were they after? For what reason had they marooned six men on a mudflat to die, and dumped a gaunt Cajun corpse on Cade's deck? And this girl who came to him out of the sea, her lips pledging devotion, her golden body promising tender ecstasy… Was she the harbinger of Cade's own death?
