This is about a hundred accounts of hauntings together in one volume, which the overly-cynical might say took Peter a fortnight and about six trips to the British Library to compile. Nonetheless, one of Ackroyd's strengths has always been as a researcher, so some of the stories herein are recently-unearthed and fascinating, whilst others are incredibly over-familiar or just plain dull. The tone veers wildly throughout, in fact, so it can be something of a choppy read if taken at one sitting, something it was almost certainly not designed for. It's a decent gift book for giving mild chills to elderly relatives, but there's very little here to distract anyone with more than a passing interest in the subject.
