What works as a young adult mystery often just doesn't cut it for an adult reader.
But that's the point. This is for younger readers who aren't going to be as critical as someone with.more experience and knowledge specifically about mysteries . . . And human nature.
I nonetheless enjoyed reading this. Figuring out who the killer was wasn't all that difficult, though the author set up numerous potential killers, any of whom would have been believable.
whether I've broken out of my slump remains to be seen.
