Query: Shallow, marginal, book tie-in to the show

This book is really an episode guide to "CSI" with some forensic science information added. Episodes of the show are referenced by title, so someone who hasn't seen all of the show may be lost. If you want a little more information on forensics or a procedure seen on the show, or if you have no additional knowledge about forensics, then this book is adequate. Otherwise, pass on it; there are much better introductory forensics books for the general public available, such as Hidden Evidence by David Owen or The Casebook of Forensic Detection by Colin Evans.
