Query: Disappointing

3 stars is kind, 2 might be too cynical. This is a quick, semi-interesting read - a little too simplistic and implausible. Some twists and turns don't make much sense, and the ending was definitely disappointing(too quick and again didn't make much sense). This book is definitely not up some of his previous books, nor does it stand with any of the other great mystery writers.
