Randall & Hopkirk (Deceased) S01E21 - The Ghost Talks

Jeff has fallen from a balcony in the line of duty and is in hospital with a broken leg. He is thus a captive audience when Marty comes to visit and regales him with the details of a big case he handled whilst he was alive and Jeff was in Scotland. He was asked by MI5 head Sir Basil Duggan to steal documents from a safe but discovered that 'Sir Basil' was actually a traitor called Brenan, whom he managed to apprehend before he could leave the country. After Marty has gone Jeannie comes in and offers to tell Jeff the same story.
