Dust and Desire — Conrad Williams

AN EXTRAORDINARY KILLER HAS ARRIVED IN LONDON, HELL-BENT ON DESTRUCTION 

Joel Sorrell, a bruised, bad-mouthed PI, is a sucker for missing person cases. And not just because he's searching for his daughter, who vanished five years after his wife was murdered. Joel feels a kinship with the desperate and the damned. He feels, somehow, responsible. So when the mysterious Kara Geenan begs him to find her missing brother, Joel agrees. Then an attempt is made on his life, and Kara vanishes... A vicious serial killer is on the hunt, and as those close to Joel are sucked into his nightmare, he suspects that answers may lie in his own hellish past.
