Two murders, days apart but clearly linked. Each victim has had the tips of their fingers removed with a hacksaw. The killer is sending a message and wants his next victim to know who they are - and be very afraid. But beside the gruesome nature of their deaths there is no obvious connection between the two victims. Reuben Maitland, freshly returned to GeneCrime, must investigate the case. The forensics come in, DNA is sampled, the clues begin to mount up. Then the killer strikes again. Reuben's young son, Joshua, is snatched from his pram. The murderer sends Reuben a message: 'Stop hunting me. I will kill again, a third and final victim and you must not stop me. Come after me and your son will die.' If your child was kidnapped, how far would you go to get them back?
