Something is stirring in London's dark, stamping out its territory in brickdust and blood. Something has murdered Saul's father, and left Saul to pay for the crime.

But a shadow from the urban waste breaks into his prison cell and leads him to freedom. A shadow called King Rat.

In the night-land behind London's façade, in sewers and slums and rotting dead spaces, Saul must learn his true nature.

Grotesque murders rock the city like a curse. Mysterious forces prepare for a showdown. With Drum and Bass pounding the backstreets, Saul confronts his bizarre inheritance - in the badlands of South London, in the heart of darkness, at the gathering of the Junglist Massive.
