Not as good as the first, I'm afraid.
Assisted by cats Murf, Misty and Pooky, Alyx tries to figure out who killed her friend and solving the robbery of a diamond from a jewelry store. Not only can the plot be summed up in one sentence, but it really didn't span the whole book so there was a lot of filler. Romantic troubles, cat troubles, most of it wasn't related to the murder. I'm going to be kind and say it's building up to future story lines.
Just ok, but not terrible.
