You Found Me

One summer morning Isabel and her eleven-year-old daughter River encounter a rain-soaked man sitting alone on a bench in Regents' Park. They ask him if he's okay. But he doesn't know. He doesn't know the answer to any of their questions - not even his name. Isabel takes him to the hospital she works at but when the tests show there's nothing physically wrong she realises she can't walk away. She promised River that they would help this man but with no way to identify him Isabel worries about what secrets his memory loss might be hiding. Can they trust him?
