Brilliantly disturbing and funny at the same time -Ben Aaronovitch (author of RIVERS OF LONDON) The fifth Laundry Files novel by Charles Stross, but also a jumping-on point for readers new to the series, The Rhesus Chart sees hacker and supernatural spy Bob Howard take on the (literal) bloodsuckers running Londons financial district. LONDON CAN DRAIN THE LIFE OUT OF YOU ...

Bob Howard is an intelligence agent working his way through the ranks of the top secret government agency known as the Laundry. When occult powers threaten the realm, theyll be there to clean up the mess - and deal with the witnesses. Theres one kind of threat that the Laundry has never come across in its many decades, and thats vampires. Mention them to a seasoned agent and youll be laughed out of the room.

But when a small team of investment bankers at one of Canary Wharfs most distinguished financial institutions discovers an arcane algorithm that leaves them fearing daylight and craving O positive, someone doesnt want the Laundry to know. And Bob gets caught right in the middle.
