This book sounds like a right laugh.

Birdman by Mo Hayder

"This crackling psychological thriller introduces police detective Jack Caffery, who is on the hunt for a serial killer the British tabloids have nicknamed "The Millennium Ripper."
The Ripper is behind the murder of five prostitutes, whose bodies are unearthed beneath the rubble of a Greenwich landfill. All the victims have been raped and their bodies horrendously mutilated--but not until after being killed by a dose of heroin injected directly into their brainstems. What stuns Caffery even more is the one detail of the murders the public doesn't know; the hearts of the women have been replaced with live birds sewn into the victims' chests."

What is the fucking matter with people?
