Keep telling yourself it's only fiction... As you read this heart-hammering thriller from the queen of London's crime scene.

Bright red. Like rose petals. Or rubies. Or balloons. Little red droplets.

Barney knows the killer will strike again soon. The victim will be another boy, just like him. He will drain the body of blood, and leave it on a Thames beach. There will be no clues for detectives Dana Tulloch and Mark Joesbury to find. There will be no warning about who will be next. There will be no good reason for Lacey Flint to become involved ... And no chance that she can stay away.
