Ben Aaronovitchs bestselling Rivers of London urban fantasy series - The perfect blend of CSI and Harry Potter .

--io9 A mutilated body in Crawley.

A killer on the loose.

The prime suspect is one Robert Weil, possibly an associate of the twisted wizard known as the Faceless Man.

Or maybe just a garden-variety serial killer.

Before apprentice wizard and Police Constable Peter Grant can even get his head round the case, two more are dropped in his lap: a town planner has gone under a tube train, and theres a stolen grimoire for Grant to track down.

So far, so London.

But then Peter gets word of something very odd happening on a housing estate designed by a nutter, built by charlatans, and inhabited by the truly desperate.

Is there a connection? And if there is, why oh why did it have to be South of the River--in the jurisdiction of some pretty prickly local river spirits?.
