You should also check out The Secret Life of Bletchley Park, more of a social history but does cover the Bombes and the work of the Post Office engineer who was the main guy behind the actual construction of Colossus.
there's also a bestseller about bletchley park [saw it at the whsmith at heathrow]:

Not sure if it's any good though; has anyone read it yet?
For Turing himself I can recommend Alan Turing: The Engima and for a wider look at the stuff he was a part of during the war The Secret Life of Bletchley Park is pretty good.
