But on her way out of the office, she comes face to face with the killer - another FBI agent.

So when the killer shows up at her door later that morning, she knows she has no choice but to run. From the moment he sees her, Mac Donovan is intrigued by - and in lust with - their beautiful witness. After Lizzy disappears, he spends his free time tracking her down. When he finally finds her on a remote island in the San Juans, their chemistry is explosive and the sex is even hotter. But he's hiding his identity from her. What will happen when she discovers who he really is? Will she be able to forgive his betrayal? Or will the killer find them first?
