A1943 scheme by Nazi Germany to assassinate Winston Churchill through an explosive bar of chocolate has been uncovered nearly 70 years later in a secret letter from a wartime spymaster. As discovered in a letter from former MI5 spy Lord Victor Rothschild to the artist Laurence Fish, it was believed that Nazis devised bombs dressed up as chocolate, with a delay mechanism which would cause the bomb to explode as it was opened. Fish was asked by Lord Rothschild to draw his impression of what such a package may look like based on its few known features. “When you break off a piece of chocolate at one end in the normal way, instead of it falling away, a piece of canvas is revealed stuck into the middle of the piece which has been broken off and a ticking into the middle of the remainder of the slab,” Rothschild explained.
