When mages make mistakes, all sorts of sadistic, giggling horrors can be unleashed upon a defenceless town. Which is why Freebridge needs Tal Djandiss, the local impcatcher. It can be a dangerous business, dealing with imps on the loose. But when people start dying, Tal realises there is a bigger threat than a few rogue imps. Most high and mighty sorcerers won't listen to a collector of vermin like him. Someone wants to silence him, though - a demon makes that very clear. And if Tal can't work out what is going on, the whole of Freebridge is doomed.
