A dead undercover cop may have been hiding more than his true identity in this edgy mystery by the author of Murderland . . .

When a young boy discovers a body lying in a doorway, DI Burton and DS Fielding are called to the scene. Initially believing the dead man was homeless, the police are shocked to discover the true identity of the victim: a Detective Constable from London who was working undercover.

But when the DNA from the victim is linked to a cold case, Burton and Fielding find themselves looking into another unsolved murder. And as the case unfolds, the detectives are faced with untangling a web of lies . . .

Bloodline is the second in the acclaimed Manchester Murders series, but can also be read as a standalone novel.
