Alex Prévost - kidnapped, savagely beaten, suspended from the ceiling of an abandoned warehouse in a wooden cage - is running out of time. Her abductor appears to want only to watch her die.

To find the young woman, the detective - a man with a tragic past and extraordinary abilities as an investigator - must first understand more about her.
