The Hornet's Sting : The Amazing Untold Story of Britain's Second World War Spy Thomas Sneum Paperback

The exploits of Tommy Sneum, the Danish-born spy who died in 2007, made him a legend in espionage circles.

But until now, the full extraordinary story of Sneum's action-packed career as a British-run spy has never been told. Based on hundreds of hours of interviews with Sneum, Mark Ryan describes how Tommy made an incredible escape from Denmark in a battered old Hornet Moth aircraft - which he had to refuel in mid-air by climbing out on the wing.

Later, he escaped from Denmark again - by walking across a treacherous frozen sea on which two of his companions died. Tommy brought over precious intelligence about the Nazi radar installations in Denmark and their atom bomb - his reward was to be imprisoned in Brixton as a suspected double agent and threatened with execution. He cheated the hangman - but it is only with the publication of this enthralling book that Sneum can be celebrated as, in the words of Professor R.V.
