Liaison with Brian Epstein?
This link talks about Orton forming "a liaison with a prominent manager of a well known music team at that time and it would have been a wonderful combination. Apparently Halliwell had found out about it and beat Joe to death with a hammer…two weeks later, sad to relate, the new found friend of Joe Orton committed suicide".

Already, one thinks of the Beatles and their manager Brian Epstein.  Add the fact that Epstein did kill himself on 27 August 1967, just over 2 weeks after Orton's murder, and it's clear who they're talking about.  But they don't name him.  Can this be corroborated anywhere?     [Talk]
