Man Hungry by Alan Marshall; Donald E Westlake

'Dan Blake, part time writer, part time author and full time lover meant these words when he spoke them to Ann. But how was he to know that Janice would thrust herself into his life. Janice, the nymphomaniac. Janice, the Lesbian. Janice, the thrillseeker? No one man could ever satisfy her. She swallowed Dan up as she had the others. Left him completely destroyed. Then went on to bait others with her gorgeous body into her deadly trap.'
