Methodical detective Sam Lagarde knows what it takes to solve a murder. But as for his personal life, he’s not certain how he managed to find romance at his age. The big mysteries for him have always been love and women . . . All the evidence in his latest case, the murder of Harold Munson, points to his wife, Charlotte, as the primary suspect. Aside from having the means and motive, she’s unbothered by the news of his death. She would much rather focus her time on her potentially Nobel Prize–winning cancer research and on quality time with her young lover. And when another body is found, she’s looking all the more guilty. However, dogged Detective Lagarde is not so sure. But identifying the real killer means diving deep into the unhappy couple’s dirty laundry and seeing who doesn’t come out clean.
