Hodges' biography manages to paint not only the story of Turing the scientist and his contribution to computing and cryptography, but also Turing the man - shy, witty, persecuted for his homosexuality. The scenes - Cambridge, Bletchley Park, Manchester - are all painted in detail, with the part Turing played in the development of mathematics, cryptography and computing clearly explored against personal and historical contexts.
A degree of mathematical literacy helps one to obtain more from this superb biography, but it should all be accessible to the non-specialist. Hodges tells a compelling story in a readable style.
