This is a book does not outstay its welcome, despite the author's unhurried style, which allows the characters time to develop, it is short and pithy.
A rather standard horror plotline is saved from cliche by the characters' believable reactions to the unfolding events, and by the convincing,well drawn setting.
A lovable rogue is our hero,a slightly dodgy antiques dealer with a perhaps too useful group of friends: it really is too convenient that he happends to know a man in the local pub who can get him a taxidermist, cat burglar or doctor on demand as and when needed by the storyline. Similarly, as the book ends a gang of religious Ghostbusters appear to assist.
All in all though, this well written and very readable work can be forgiven for taking an odd shortcut.
I wonder if the author had the idea for the book when musing "I wonder what would hapen if Lovejoy met Lovecraft...?" We can only hope so.
