Come for the quirky "who-done-it" plot; stay for the existential reflection and character development.

It's true that I was looking for a light, well written mystery to escape into. The Last Devil to Die is exactly that. A drug delivery to an "antique" store leads to murder, several local dealers questioning their life choices, and more murder. The aging Scooby crew are at it again.

But the real meat of this story comes from the quiet character of Stephen -- wife of the leader of the crew (Elizabeth/Velma). As the crew is aging, the book hinges on Stephen's progressing dementia and its effects on those around him. As we are all aging, it gives a lot to reflect on.
