Sunburn : a novel / Laura Lippman.

Enhanced descriptions from Syndetics:

New York Times bestselling author Laura Lippman returns with a superb novel of psychological suspense about a pair of lovers with the best intentions and the worst luck: two people locked in a passionate yet uncompromising game of cat and mouse. But instead of rules, this game has dark secrets, forbidden desires, inevitable betrayals--and cold-blooded murder.

One is playing a long game. But which one?

They meet at a local tavern in the small town of Belleville, Delaware. Polly is set on heading west. Adam says he's also passing through. Yet she stays and he stays--drawn to this mysterious redhead whose quiet stillness both unnerves and excites him. Over the course of a punishing summer, Polly and Adam abandon themselves to a steamy, inexorable affair. Still, each holds something back from the other--dangerous, even lethal, secrets.

Then someone dies. Was it an accident, or part of a plan? By now, Adam and Polly are so ensnared in each other's lives and lies that neither one knows how to get away--or even if they want to. Is their love strong enough to withstand the truth, or will it ultimately destroy them?

Something--or someone--has to give.

Which one will it be?

Inspired by James M. Cain's masterpieces The Postman Always Rings Twice, Double Indemnity, and Mildred Pierce , Sunburn is a tantalizing modern noir from the incomparable Laura Lippman.
