The police call him Merkury. He's a killer who seems to choose his victims at random. He leaves no evidence behind, and no witnesses. Except for one. But what did she really see?



When Kate Summerlin was eleven years old, she climbed out her bedroom window on a spring night, looking for a taste of freedom in the small college town where she was living with her parents. But what she found as she wandered in the woods near her house was something else: the body of a beautiful young woman, the first of Merkury's victims. And before she could come to grips with what she was seeing, she heard a voice behind her—the killer's voice—saying: 'Don't turn around.'



Now, at the age of twenty-nine, Kate is a successful true crime writer, but she has never told anyone the truth about what happened on that long-ago night. When Merkury claims yet another victim—a college student named Bryan Cayhill—Kate finds herself drawn back to the town where everything started. She sets out to make sense of this latest crime, but the deeper she gets into the story, the more she comes to realize that it's far from over. Her search for the truth about Merkury is leading her down into a dark labyrinth, and if she hopes to escape, she'll have to meet him once again—this time face to face.
