Book excerpt: The Piltdown Man hoax began in 1912, when Charles Dawson claimed to have discovered fossils belonging to a "missing link" between man and ape. For decades it was the subject of heated debate among paleontologists. It wasn't until the early 1950s that the hoax was revealed, though it continued to be a mystery as to the identity of the hoaxer. This book traces the story with new research from the archives of the British Museum (Natural History) to find an answer.
