The full title is Animal Investigators: How the World's First Wildlife Forensics Lab Is Catching Poachers, Solving Crimes, and Saving Endangered Species. I had heard an interview with the author and decided to pick this up and give it a try. The book covers a few completely different cases in the US that the lab worked on. They discuss how they came up with different ways to tell how a walrus died in order to show they were killed only for their ivory. the book doesn't get into the hard science that much but it was a rather interesting peek into the world of wildlife protection.
