 Alan Turing: the Enigma (Andrew Hodges) 
  Hodges, like Turing, is a mathematician, and was thus able to understand and describe Turing's pioneering work in mathematical logic —; and his momentously important codebreaking work during the war — at a depth that would have been beyond most biographers. 
  Like Turing also, Hodges is gay, and his description of Turing's prosecution in 1952 for 'gross indecency' and the tragic events leading up to it, is written with great empathy and an entirely appropriate indignation. 
  It is an almost perfect match of biographer and subject, and, though Hodges is determined, as he puts it, 'to overcome the twentiethcentury chasm between scientific thought and human life,' he has the sensitivity to realise that the events of a person's life can never 'explain' the greatness of their thought.
