Muddy footprints, buried bodies, and gem and mineral fraud are some cases in which forensic geology can play a part. Murray, an academic geologist before discovering his true calling, introduces the field to readers with or without a background in geology or law. Among his topics are from Sherlock Holmes to the present, the origin and distribution of earth materials, evidence collection, geophysical instruments and the search for bodies, and the status and future of forensic geology. Earlier editions were published in 1975 and 1991. Annotation 2011 Book News, Inc., Portland, OR (booknews.com)
