Third Degree - Greg Iles

Laurel Fields, perfect wife of Dr Warren Fields, living in a perfect house in a beautiful town, is pregnant. But is the baby her husband's - or her lover's?

One morning she returns home and finds Warren waiting for her. When she looks down from his unshaven face, she recognises the piece of paper lying on the coffee table - a letter from her lover Danny that she'd hidden inside a book.

Then she sees the gun in her husband's hand.

It's going to be a long day: for the Fields family, for Danny, for the police. Because this is not the only secret in town.
