Query: interesting, but gruesome, in some places, type of book.

This book, part series guide; part primer on forensic science, gives some of the scientific background to C.S.I.. (Crime Scene Investigation) and now, also, C.S.I. Miami, as well as other movies and shows; where science and criminology meet. Gives fairly good explanations, although some are left out, maybe because anyone who watches these shows has heard terms, for example, "bindle" [a piece of paper or some small envelope, used for evidence collection]. Some of the "real life" cases, as contrasted to some of the episodes, are pretty gruesome and not recommended for everyone. Great for fans of the shows [like me] or anyone moderately curious about how some crimes are solved.
