** Something Nasty in the Woodshed, Kyril Bonfiglioli, 1979
Yet another entry in the Books Sent To Me By The Learned One series. Total change of venue from the first two in the trilogy. Set on the Isle of Jersey with the story line moving from international crime and intrigue to trying to catch a brutal serial rapist who is using pagan/satanic paraphenalia/symbols. The bulk of the story is taken up with a bizarre scheme to hold a black mass to intimidate the bad guy into stopping. Then, at the end, it just blows up.
Bonfiglioli has an entertaining style, but no clue about story structure.
