A second stunning Brighton-set crime novel featuring DS Minter, from one of the sharpest new voices in British crime writing.

On the surface, John Slade appeared quite normal. But when Martin, a young biochemist, ran a behavioural experiment, he discovered a boy without inhibitions or moral qualms: the perfect subject for a series of experiments Martin had never dared try...

Twenty years later, Brighton is facing a serial killer. DS Minter investigates the most bizarre and disturbing murder of his career; the dismembered body of a local woman dumped on a station platform. And when another body is found, Minter realises he is hunting a brutal killer with an IQ off the scale, the likes of which the city has never seen.
