A short story by Jack Gerson
THE GREAT UNCLES (ITV, 21/02/1973)

Do any examples of 'Late Night Theatre' survive?
TV Times had this tantalizing preview:

Mystery, suspense and drama when a teenage orphan comes to stay with two great-uncles. One of the uncles is aware that the young man has a guilty secret, but having experience of both guilt and secrecy in his own past, he has his own way of dealing with the situation.

Richard Harbord - 'Alan Sligh'
Alan Webb - 'George Gascoyne'

What became of Richard Harbord? He has (or had) only one other screen appearance:
'Johnson' in THE DUNA BULL (TV, 1971).

Alan Webb had a successful acting career with over 50 roles. He died in 1982.
