In this newest entry in Andrew Klavan's USA Today bestselling Cameron Winter series, the ex-spy turned English professor finds love—and murder. After working up the courage to contact Gwendolyn Lord, Cameron Winter finds himself immersed in a heaven-sent passion. When Gwendolyn tells him about a true-life "locked room mystery", Winter is compelled to investigate. In Tulsa, Oklahoma, Owen McKay suddenly went mad and killed his wife and child. Locked in a cell and monitored on video, he was discovered dead from a projectile fired into his head. Then, another mysterious death, just like McKay's, takes place in Connecticut and both murders seem linked to a sinister billionaire who once clashed with Winter's old mentor, the Recruiter. Winter's past and present are coming together in a dangerous conspiracy. And though Winter desperately wants to escape his career as an assassin, his love for Gwendolyn is deepening quickly and he will do anything—and kill anyone—to protect her.
