The woman lies dead at the foot of the stairs. It's obvious what happened: she tripped and fell. But PC D'Arblay, called to the dilapidated West London villa by an anonymous tip-off, can't shake the feeling that's exactly what someone wants him to think.

It was the deep head wound that killed her - but her dying fall left no blood trail, so what was it she hit her head on?

DCI Slider, of the Shepherd's Bush murder squad, is soon convinced D'Arblay's right. But with no motive, no murder weapon and no idea even who the victim is, Slider faces steep odds to get a result . . . while each painstaking step towards the truth brings him closer to a ruthless, evil killer. The Bill Slider series is in "a league of its own" (Publishers Weekly Starred Review). If you haven't met Slider and his team yet, why not start now?
