Edgy Taylor sees demons. They walk among us, masquerading as humans, but he can see through their disguises. So when Edgy discovers the Royal Society for Daemonologie, he hopes that at last he will find some clue to the origins of his mysterious ability. Within the Society's ancient walls are the answers to many secrets. And when Edgy joins their expedition to the Arctic Circle, he sails through icy seas towards the darkest secret of all . . .

Edgy Taylor sees demons when nobody else can. The only thing Edgy is good at is setting and solving riddles, and evading his brutal and abusive master. One night, when his master seems genuinely intent on killing Edgy, Professor Envry Janus intervenes. Envry takes him to the Royal Society of Daemonologie and it is here that Edgy discovers that holds the key to a deadly demon prophecy. The follow up to the brilliant Mortlock, think Jonathan Stroud meets Charles Dickens. A darkly humorous hugely imaginative and utterly gripping story of a time when demons roamed London's underworld.

Praise for The Demon Collector:

'Mortlock was a striking debut . . . it created a creepy atmosphere that won much praise. The Demon Collector is equally full of well-written suspense but far funnier, with a strong filmic element that fans of Joseph Delaney's Spooks Apprentice and Anthony McGowan's Hellbent will lap up . . . Boys will love the rich vein of disgusting humour and the fact that demons can't resist riddles - which the well-named Edgy is good at making up and solving. Mayhew's demons are scary enough to be exciting but, unlike those of Darren Shan, not depressingly sadistic. These are demons with style, and they're here to stay'
