According to your site Neville George Clevelly Heath was executed 16th October 1946.
On the site I searched it said he murdered two women.
1. Margery Gardner
2. Doreen Marshall.
Does it not fit kentishman's other clues?
the answer is correct
he had other names. Born Neville George Clevely Heath, in Illrord Essex 1917, although in later years he would use the alias of Group Captain Rupert Brooke, as well as many others.
