Cameron Winter is falling in love. After finally working up the courage to contact the attractive therapist Gwendolyn Lord, he finds himself immersed in a passion that feels heaven-sent. When Gwendolyn tells him about a true-life "locked room mystery," Winter feels compelled to investigate. In Tulsa, Oklahoma, a solid citizen named Owen McKay suddenly went mad and killed his wife and child. Locked in a padded cell and monitored on video, he was nonetheless discovered dead from a projectile fired into his head. As Winter begins to ask questions, he finds Tulsa officials have been intimidated into silence by a killer who once tried to attack Winter during his days as a government assassin. What's more, another mysterious death, just like McKay's, has taken 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 single 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.
