This new biography of Turing is short, the length of a long article or essay rather than a full book. If you want a detailed exploration of the life and work of Turing, you’ll have to look elsewhere, but this is a good overview that’s well worth reading. It’s well balanced on coverage of his personal life, his work at Bletchley Park, and his academic work, tying them all together so you can see how one element affects the others. It also brings the story up to date as I write this, having been prompted by the campaign for a posthumous pardon, and there’s some interesting material about that which won’t be in the older biographies.
It’s well written and edited, solidly grounded in known facts but enhanced by the author’s clearly marked interpretation of some of those facts to make it more than a dry recital, and I found it a very enjoyable read. If you’re looking for something a little more in-depth than the online articles without diving into the full length works, this is an excellent introduction to Turing. I think it will also serve well as a synopsis volume for those who want an outline in addition to the full length studies.
The Kindle Single is currently priced at 99p, and excellent value for money at that price, even if a significant chunk of the stated page count is a preview of another book by the author. It’s also available in a paper edition, although I’m not convinced that most readers would find it value for money unless they’re die-hard completists, unable to use Kindle format ebooks, or looking for a gift for a Turing fan. There’s also an audiobook version.
