This seems an unusual book in that I've not seen its like. It is an anthology of 99 "cases" that have been experienced, or told by others, to the author. Most of them are personal in that they occur near the home village of the author, but she has included some "famous" cases - such as the now totally debunked "Ammityville Horror" case.
They did make nice "bathroom" reads, though. The vast majority of the stories were a page or so in length.
