In this riveting thriller from the Queen of Suspense and #1 New York Times bestselling writer Mary Higgins Clark, the mystery of twin telepathy is brilliantly woven into a mother's desperate search for her kidnapped child, presumed dead.

When Margaret and Steve Frawley return home to Connecticut from a black-tie dinner in New York, they find their three-year-old twins, Kathy and Kelly, gone. The police discover the babysitter unconscious, and a ransom note from the "Pied Piper" demands eight million dollars. Steve's global investment firm puts up the money, but upon retrieving the twins, only Kelly is found in the car. The dead driver's suicide note claims he inadvertently killed Kathy.

At the memorial, Kelly tugs Margaret's arm and says: "Mommy, Kathy is very scared of that lady. She wants to come home right now." Initially, only Margaret believes that the twins are communicating and that Kathy is still alive. But as Kelly's warnings grow increasingly specific and alarming, FBI agents embark on a desperate search.

As the tension escalates, the FBI closes in on the "Pied Piper" and his accomplices, with Kathy's life hanging by a thread.
