Jack Olsen did a great job of setting the scene and sharing his research into these horrific crimes. I’ll admit, there were times I felt like I was there.
The pros for me were a great narrative style and the ring of truth.
The cons were that I didn’t need to know quite so much about Houston in that era, and (something the author couldn’t help) the fact that the climax of the book, in many ways, came about three-quarters through. The rest was just housekeeping, really.
