Sam Seymour hires Jeff to go to Glasgow and retrieve a valuable 'item'. This turns out to be his girlfriend Dandy Garrison, who has a case chained to her wrist. On arrival back in London Dandy disappears, fitting Jeff up to appear to be her accomplice. In reality she has gone off with Tony, one of Seymour's men and they have stolen a very valuable stamp. Dandy tries to double-cross Tony as well, by escaping in a private plane but Marty brings her down to earth.

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.
