If you're looking for a mystery, this one is It.

I have read quite a few of Ware's books, and have enjoyed them.  This one was wonderful, and had me guessing throughout.  

I enjoyed the characters, and the protagonist especially grew on me.  The pacing and plot development were well done.  

I thought it was a well done mystery, and told my sister-in-law, that it was a brilliant set-up when I reached the end.
