Animal Investigators is an excellent book, timely, well-written, and fascinating. And it gives important credit to the USFWS Forensic Lab which has in recent years done outstanding and critical work, as the cases in the book illustrate. I have been a little involved in the shahtoosh wool problem -- the wool of Tibetan antelope -- and the lab has been of critical help in distinguishing antelope from domestic goat. I wish the book well deserved success.
