Both of them turn up at the tryst at an hotel, unaware that it is a ploy to get them away whilst she and her boyfriend are robbing their shops. Fortunately Ringo saves the day - albeit by accident when he locks himself in the shop and calls the police.
The two dealers plan - separately - to spend a night at a country pub and are surprised to meet each other there, especially as they have to share a bed in the one guest room. Each is hoping to beat the other in a bid for a grandfather clock at a nearby action but, after Oliver has been locked out for the night in his pyjamas, their bickering means that neither ends up with the clock.
Whilst drinking in the pub with Oliver Simon reveals that he is adopted, having been abandoned at an orphanage as a baby. Circumstances lead him to believe that his natural parents may be Charlie Crapper, a drunken petty thief, and his wife Lil, who sells papers on the street. He meets with them to break the bad news but fortunately they know something he does not.

Lady Devereaux offers Simon some sporting memorabilia at knock-down prices provided he captains her staff cricket team against the rival side led by parvenu bookie Bernie Miller.

Miller's side gets thrashed and he has to pay her the money from the bet that his boys would win. Unfortunately for Simon this means that she no longer needs to sell him...
