In 1956 the Russian leadership paid a State visit to Great Britain.

This in itself was appalling and shameful...(that the British would allow such a thing to occur)...and it got even worse when a British diver was murdered.

An elderly Russian has come forward as the murderer and elaborated on the half a century old mystery of what happened to 'Buster Crabb'.

This article in The Times also has some background information for those unfamiliar with this most disgraceful of incidents.
