Rachel Mullen has been murdered, and when Inspector Lottie Parker discovers a shard of glass in her throat, she fears she may be the victim of a serial killer. The night before, the girl was at a party at a fancy new restaurant, and Lottie is concerned that Rachel's purse and keys have gone missing and that no one at the party saw her leave. Just when Lottie thinks she has a lead, her worst fears come true: another woman has been found... with a shard in her throat. But the young doctor wasn't a guest at the party, so Lottie is still at the beginning. And then her fiancé Boyd goes missing. Can Lottie get inside the mind of the twisted killer before it's too late? Or will the man she loves be silenced forever?
