Video report by ITV News Anglia's Matthew Hudson
A 1940's Nazi spy, buried in secret by British authorities in Cambridgeshire 76 years ago, is about to get a headstone on his unmarked grave.
William Ter Braak was parachuted into Britain and began living in Cambridge, supposedly with a clear mission - to kill Winston Churchill in World War Two.
After spending several months spying for the Germans and fearing he was about to be caught, he killed himself in an air raid shelter in Cambridge park.
He was buried in secret by British authorities fearing a public scandal.
But now, after 76 years, he's about to get a headstone.
Now parish councils have finally agreed to allow a headstone to be erected on his grave at Great Shelford cemetery, just outside of Cambridge.
But experts believe a story that he came to assassinate Winston Churchill is nonsense
Giselle Jakobs, who's grandfather was also a spy, hopes to publish a book.
I have a draft, last year I submitted it to one literary agent who said it wasn't quiet commercial enough. So I am sort of reworking it and taking it a bit broader to include some of the other spies.
