What the rising action to after twenty years by o Henry?

The man in the doorway lights a cigar and talks with the officer,

telling him that he is meeting an old friend after twenty years.

The policeman converses with the man, asking about his friend. The

man assures the policeman that his friend will come; the policeman

asks him how long he will wait for his friend. "I'll give him half

an hour, at least," replies the scar-faced man with a diamond tie

pin.
