A woman is witness to an act that could cause the man she loves to face trial for murder in this mystery thriller from an Edgar Award–winning author. She was known on the island as Sister and she always tried to do the right thing. But when she comes upon Tom, the man she secretly loves, pulling a woman's body from the water, a hammer in his hand, Sister doesn't know what to think. She doesn't believe Tom is capable of killing. She can't believe it. Before going to the police with what Sister saw, Tom proposes. If they marry, she won't have to testify against him. How far will Sister go to protect the man she loves? And if Tom isn't the murderer, the killer must still walk among the small island community—which means they could strike again . . .
