The book I read to research this post was The Final Dive by Don Hale which is an excellent book which I borrowed from the library. Anyone acquainted with my history posts will know I like controversial history & I am in my element with this book. For anyone not familiar with the Buster Crabb story he was a diver who when Kruschev who later became premier in the soviet government visited Britain via a soviet cruiser & an escort of 2 other ships. He went diving near these ships & disappeared although a badly mutilated body which they were unable to identify turned up a year later. This case resulted in a big shake up of the security services & contributed to Anthony Eden's governments downfall. A lot of people suspected that Buster Crabb was a spy. Apparently he had loads of experience as a diver in the navy. The ship that Kruschev came on was a new type of cruiser & it has been claimed that Mi6 wanted him to film under the hull of the ship & its propellers. This incident happened in the 1950's & anglo-soviet sunk to an all time low. Also once the newspapers got hold of the story it became a very big story. This book is like a biography of him although I'm going to concentrate on the disappearance. One thing that has never been fully explained is why it was necessary to film under the ships hull. Apparently had photos of its hull from when it was being built. The theory in the book is that they knew there would be a scandal & that they wanted to get rid of a lot of the bosses several of whom since have been found to have been soviet spies.
