This is a memoir of the author‘s time profiling serial killers and violent criminals. It‘s informative but far from prefect. The author spends a bit too much time boasting of his accomplishments. I think it helps to keep in mind this was published in 1993. I have a high tolerance for tragedy, but I have to admit I was a bit disturbed at times with the constant barrage of violent stories told in the author‘s direct and somewhat dispassionate style!
