"A gripping first novel ... taut and fast-moving." —Washington Post
Renowned psychologist Joseph O'Loughlin has it all—a thriving practice, a devoted, beautiful, fiercely intelligent wife, and a lovely young daughter. But when he's diagnosed with Parkinson's, O'Loughlin begins to dread the way his exceptional mind has been shackled to a failing body, and the cracks in his perfect existence start to show.
At first, O'Loughlin is delighted to be called in to a high-profile murder investigation, hoping his extraordinary abilities at perception will help bring a killer to justice. But when O'Loughlin recognizes the victim as one of his former patients, an emotionally disturbed young woman who nearly brought ruin upon him, O'Loughlin hesitates—a fateful decision that soon places O'Loughlin at the top of the lists of both a bullish detective and a diabolical killer.
