Some oldies like me, may remember Freddie Mills as a world boxing champion who went on to be an entertainer in the 50s and 60s.
I saw him in Blackpool with a show with Dickie Henderson.

An article about a book on his secret life names him a killer called Jack the Stripper who was never found but stripped prostitutes, strangled them and knocked their teeth out.

He is said to have confessed to a policeman in his Freemasons lodge, then paid the Krays to kill him and make it look like suicide.
