Query: Disappointing

I've read most of the Alex Cross series and each one has gotten worse and worse. This one starts out with a bang and is a real page-turner for the first half of the book, but peters out with a disappointing middle and abrupt ending. Very unsatisfyingThis is one of the few mysteries where I guessed the culprit which took a lot of the fun out of the book. It was an obvious choice but didn't really make sense.It's clear James Patterson doesn't think much of his readers. This is the last James Patterson book for me.
