One of my favourite telly programmes when I were a lad was Hogan's Heroes, and I have been enjoying the occasional re run . What I hadn't realised until recently was that Bob Crane who played Hogan was murdered in his flat a the age of 49. Apparently bludgeoned to death in his sleep, his body was removed from his bed and a length of cord tied in a bow round his neck. Crane was apparently a bit of a ladies' man and filmed his sexual exploits in the flat and suspicion fell on jealous boyfriends and husbands, as well as a friend of his. The latter was tried and found not guilty and died soon after. The case has weirdly never been solved.
Incidentally many members of the cast had fascinating histories, Clary who played Lebeau survived a concentration camp and others only escaped the Nazi regime by the skin of their teeth. One wonders why they wanted to partake in the series(money aside of course).
