This is a "bonus" novella in the Pitkirtly series. Someone's organised a coach trip round Pitkirtly to all the murder spots. No, the organiser doesn't get murdered. Although I'm sure Amaryllis would like them to. This story is about the mystery about who the organiser is.
We visit many of the scenes of the previous stories. This is like a gentle reminisce of what's (and who's) gone before. There are quite a few locations that are on the coach's itinerary. Considering Pitkirtly is a quiet backwater town, it's a dangerous place to visit.
I enjoyed this story, even though it was not quite a "proper" one.
