The Murder of an Angel is the fourth and final book in the Confessions series.
Tandy Angel has solved several murder cases since the death of her parents however none try her wits more then attempting to figure out who is trying to kill her. Having taken Angel Pharmacy special pills to make her smarter, more focused, and sharper for years Tandy constantly wonders if she is crazy and hallucinating. Several times I wondered the same thing.
The writing was a bit weak at times with setting up characters, unlike previous books in the Confessions series it was pretty obvious who the criminal was. Despite the problems with the overall mystery I did like the way the writing was done and how Tandy constantly questioned her sanity. My other issue was several things felt unfinished at the end, the relationship with CP, James, and Tandy was not well done and ended on a strange note. I also was not a fan of how the mystery was resolved.
