Another instalment in the Devon-set series of crime stories featuring Wesley Peterson. This one starts with a man found dead in his own tourist attraction - an escape room, popular with stag and hen parties. He's checking the room after the latest party and finds himself shut in, and the police believe it's a case of negligence, as the CoD was carbon monoxide poisoning, presumably from a faulty boiler flue which was meant to have been fixed (a bit too much info about boilers in this case!). The police become more involved when the plumber who had done work on the boiler asks Wesley's boss, Gerry, for help as he could be facing a manslaughter charge. Meanwhile, a retired couple are shot dead in their home, the man was an ex Met police officer who had recently set himself up as a private investigator, so the police start to look into his past for a possible motive. Then an American woman visiting a local resort hotel goes missing, and it soon emerges that all these people had been sent an invitation (anonymously) to another attraction, a ghost tour set in a former mental hospital, which had a formidable and shameful history. When yet another victim, this time an elderly man, is shot dead, further links to all the cases begin to emerge. Coupled with this is a back story from the 1950s, of a young woman,a teenager, who is pregnant by a married man, and who is about to be banished to protect her wealthy family (and the man) from losing their public respectability. The young woman seems to just disappear, judging by the pages of her diary, and there is also a historical link, as usual, to the dig on which Wesley's friend Neil is working, which is excavating an old church, with a possible anchoress's cell (a woman who gives up her life to God, and is walled up into a small chamber for the rest of her life, normally next to a church). so a lot going on, and whilst the links and general direction that the plot is heading do become apparent, it was still a very densely plotted novel,with some good misdirection, even though some elements become clear after a while. But the author doesn't go down the obvious path, which was good, and this was another enjoyable read, although a bit dry at times. Some humour is provided, as usual, by Wesley's mother in law, the ever youthful Della, who inadvertently does help with the case. 7/10
