This is the 4th or 5th time I've read the book, describing the most embarrassing episode in my profession. The "Piltdown Man" of England, "discovered" at various times between about 1908 and 1915, by 1955 became the "Piltdown Forgery." Weiner is one of the scientists who actually uncovered the hoax/forgery and wrote a pretty readable book. Weiner describes in great detail how the hoax was first suspected (by many), covered up by the power brokers of English science, then exposed using methods developed in the 1940's, including refined fluorine dating, carbon dating and various chemical tests finally put to the fossils and accompanying artefacts. It is a detective story, a forensic-based detective story meticulously described. I used the book in several of my "Human Discovery" classes. More has been uncovered since the book was written but this covers the basics and the original exposure, In true English fashion, Weiner does not directly accuse Charles Dawson, of deceit, but makes a very good circumstantial case, including use of a phantom Mr Hyde to match Dawson's Dr. Jekyll. A good scientific mystery, and a real one!!
