Book excerpt: Ten gripping tales of murder and missing persons show how skulls and skeletons reveal their secrets to forensic investigators. A skull is found on a scree slope high above the mirror-calm waters of Spray Lakes. Bones rumoured for years to be buried in a Medicine Hat backyard are finally dug up. The trussed and tortured skeletal remains of an unknown man are found in a septic tank near Tofield. These baffling Alberta cases show how dogged, old-fashioned detective work combines with modern forensic techniques in the search for the truth.
