Tom Ballard was a retired accountant who spent his final years in the Bayview retirement home where he became lovers with former photo-journalist Diana Trent. Tom had a very active imagination and would often regale other Bayview residents (especially the ladies) with tales about his adventures as an explorer and of his prowess as a Hollywood actor.
Tom's father may have had a brother who also had a son - Samuel Ballard, often referred to disparagingly as "Soapy Sam" by fellow counsel Horace Rumpole. Sam Ballard took advantage of Rumpole's journey to Africa on a case to become the head of Chambers, which kept him in constant conflict with Rumpole.
Besides, there's a better candidate for a brother for Tom Ballard, although I suggested in a previous post that he could be related to a Patrick McGoohan character.
I went with that theory because I was offered a bribe, and I still haven't collected......
