FOM: Turing, Gandy and the British Secret Service

[Andrian-Richard-David Mathias]

Turing died of cyanide poisoning. His mother wrote a life of him 
advancing the view that his death was accidental; he had been using cyanide 
for some biological experiments. 

In an informal conversation with me and others, Gandy said that 
Andrew Hodges, the author of the book about Turing, had originally intended to 
state that Turing had been killed by the British Secret Service 
(presumably because they would view him as a security risk) 
but that he, Gandy, had persuaded Hodges not to make that statement.
