Rat Scabies and the Holy Grail - Christopher Dawes

Chris Dawes lives in a quiet street in Brentford, opposite Rat Scabies, former drummer with The Damned and best noted for setting his drums on fire while playing them.
Life with Rat as a neighbour isn't run-of-the-mill and things turn even stranger when Rat announces that the two of them are going on a search to find the Holy Grail.
The sacred relic has eluded everyone from King Arthur to Monty Python, but Rat reckons he knows where it's stashed.

Once they've written a list of things to do ("Buy metal detectors!") the pair get to work on unravelling the mystery, which involves the Knights Templar, the ancient sorcerer Kings of France, a shadowy secret society called the Priory of Sion, the CIA and the remote and spooky village of Rennes-le-Chateau in the Pyrenees, where it begins to look as though someone - or something - wants to stop them from finding out anything at all ...

RAT SCABIES AND THE HOLY GRAIL is a psychedelic road trip, a rich historical yarn, and a testimony to the sometimes odd nature of certain friendships.
