I have always been interested, in a moderately morbid way, with criminal forensics, and I very much enjoyed reading this non-fiction book, not least because it was written by someone in Great Britain, which puts another spin on the subject.
After introducing the reader to Locard's Principle, which is that "every contact leaves a trace", Dr. Zak (as he was known by his colleagues at Cambridge; born in Turkey, and a noted entomologist, he died in 2002, aged only 50) devotes individual chapters to The Forensic Mind, Spirit of Place, Time Will Tell, A Question of Identity, Causes, Poison, Destruction, Words and Images, and Little Details, ending the book with a chapter about The Criminal Mind. Along the way he mentions famous cases, and puts forth a few interesting theories (that the Czarevich did not die at Ekaterinburg, and that King Harold was not killed by being shot in the eye with an arrow at the Battle of Hastings).
I very much enjoyed reading this book; while the good doctor is no longer with us, he did write other books, and I will be on the watch for them.
