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.
