He knows how killers think. But what if this killer knows more?

It's raining when psychiatrist Andi Manette leaves the parent-teacher meeting with her two daughters. She's tired and distracted, so she doesn't notice the red van parked beside her, or the van door slide open. The last thing she does notice is the hand reaching out for her and her girls . . .

Hours later, deputy chief Lucas Davenport stands in the car park holding a blood-stained shoe in his hand. He knows that this case will be difficult, but he's got no idea that he might have met his match in a nemesis more intelligent - and more depraved - than any he has tracked before. A killer who knows more about mind games than even Davenport himself.

Time is running out to find Andi and her daughters.

Will this be the one case that Davenport can't solve?
