Lost

Detective Inspector Vincent Ruiz can't remember how he got to the hospital. He was found floating in the Thames with a gunshot wound in his leg and a picture of missing child Mickey Carlyle in his pocket. But Mickey's killer is already in jail. Add to this the blood stained boat found near where Ruiz was pulled from the water, and the pieces just don't add up. Now, accused of faking amnesia and under investigation, Ruiz reaches out to psychologist Joseph O'Loughlin to help him unlock his memory, clear his name, and solve this ominous puzzle.
