Paying the landlord:
 Give the betting slip to the barber. He'll ask you if you 
 want to make a bet. The odds are 25:1. You will now have 
 enough money to pay the landlord.
 
 Propose to Frankie: 
 Give the ring to Frankie after rescuing her. 
 (She will "think about it.") Show her the diamonds 
 before turning them over to the police. She will kiss 
 you and accept your proposal.
