Jefferson Winter is no ordinary investigator.

The son of one of America's most renowned serial killers, Winter has spent his life trying to distance himself from his father's legacy. Once a rising star at the FBI, he is now a freelance consultant, jetting around the globe helping local law enforcement agencies with difficult cases. He's not got Da Vinci's IQ, but he's pretty close.

When he accepts a particularly disturbing case in London, Winter arrives to find a city in the grip of a cold snap, with a psychopath on the loose who likes abducting and lobotomising young women. Winter must use all his preternatural brain power in order to work out who is behind the attacks, before another young woman becomes a victim.

As Winter knows all too well, however, not everyone who's broken can be fixed.
