The other day when we went to the gym I found a book that someone had left behind. It's called Pop Goes the Weasel by James Patterson. I have read quite of few of Patterson's thrillers before and always enjoy them. This is one in the series of Alex Cross books, the detective/psychologist who is on the trail of a serial killer in Washington D.C. Here is Patterson's website with an excerpt from the book:
This book has short chapters and is a quick read. I'm about a third of the way through it already.
