This is a STRONG book. Like there's a difference between "good Doctor Who" and "good book" that certain EDAs fall foul of, but not this one. The Turing Test is a really good book.

The three narrators work well, each showing a different facet of the newly-memoryless Doctor, definitely helped along by the fact that as a queer computer scientist I am always sad about Alan Turing. The ending was tragic. Paul Leonard only used the word "bawled" once, which I think is a new record for him.

Just. what a good book
