My kingdom for an updated version of this book!
I've been going through a few of the Writer's Digest books on how to write a mystery. The last one, whose title I can't even remember, was pretty damn dry. This one? Written by a writer for writer complete with anecdotes and suggestions for ways procedure could go amiss.
Unfortunately, it is now woefully out of date. DNA procedures, especially, have evolved. I think photography is different. A lot of this still probably works in a similar manner, though, so I may buy my own copy. (This one was checked out of the library)
Also, I found Wingate so charming, I will try to find some of her books.
