Lost

Detective Inspector Vincent Ruiz is lying in a London hospital bed trying desperately to recover his memory. He was found unconscious on a boat on the Thames, covered by the blood of two people - both of whom are missing, along with a #300,000 ransom. Ruiz can remember nothing of this. Instead he is haunted by memories of a seven-year-old girl, Mickey Carlyle, who vanished from the stairwell of a mansion block three years earlier. In Ruiz's nightmares Mickey is four feet high, tugging at his sleeve, saying, 'Why didn't you ever find me?' Ruiz knows that she's dead and he knows who killed her, and he realises they're now coming after him . . .
