Killing for Sport was a very enjoyable book. Written by a profiler who knows quite a bit about serial killers and how they operate.
Reading the book was like having a Q&A with the author and killers both. Ms. Brown asked questions that we all wonder about regarding how these murderers do what they do, then goes on to answer them.
The author tried to add light humor along with the information which at times I felt was in bad taste, but then again, murder is in bad taste. I understand that in this kind of job you have to find humor where ever you can to keep your sanity.
I listened to the audio version.
