The fourth monkey - J. D Barker

'The Fourth Monkey has one of the most ingenious openings that I've read in years. This thriller never disappoints.'
James Patterson

'Superbly constructed and immaculately paced' - The Daily Mail

Brilliant. Complicated. Psychopath.

That's the Four Monkey Killer or '4MK'. A murderer with a twisted vision and absolutely no mercy.

Detective Sam Porter has hunted him for five long years, the recipient of box after box of grisly trinkets carved from the bodies of 4MK's victims.

But now Porter has learnt the killer's twisted history and is racing to do the seemingly impossible - find 4MK's latest victim before it's too late.
