Product Description Now available in paperback -- the history of fingerprinting, as "fascinating, informative and as gripping as a great crime novel" --Simon Singh, author of Fermat's Enigma and The Code Book.
It is almost impossible to imagine that prior to the 20th century, there was no reliable way to distinguish between the guilty and the innocent. All that changed in Britain in 1905, when the bloody bodies of an elderly couple were discovered in their shop -- and a solitary fingerprint became the only piece of evidence . . .
