Frank receives a job as a telegram boy. On his first day of work he receives the family telegram, and is told by the boys at the post office he is lucky as they give a shilling tip, one of the biggest in Limerick. Being the junior boy Frank does not understand why he receives such a wealthy house. It is then revealed to him by the other boys that it is because of Theresa Carmody, a 17 year old girl who sometimes answers the door, she has the consumption. The boys are fearful they will catch it from her and say sick people like Theresa know they have little time left, which makes them desperate for love and romance. .
As Frank approaches the Carmody house on yet another wet day in Limerick, his bicycle slides from underneath him and he falls scraping his back and tearing open the back of his hand. He knocks at the door bleeding and soaked with rain, the consumptive girl Therasa answers, and tells Frank to come in and she will clean up his cuts. Frank is fearful of going in as he may catch the consumption, but enters anyway. Theresa cleans his cuts with iodine and tells him to put his pants by the fire to allow them to dry. Frank embarrassed, stands facing the fire without any pants on and his "excitement" rises. Theresa enters the room after Frank and acknowledges his "fine boyo," she leads him to the green couch, where they make love. It appears Theresa is a confident girl, certainly being the dictator of the two's actions.
Frank is confused with what he is doing and thinks: "my head is filled with sin and iodine and fear of consumption and the shilling tip and her green eyes and she's on the sofa don't stop or I'll die and she's crying and I'm crying. I"m riding to heaven I"m falling off a cliff and if this is a sin I don't give a fiddler's fart. " This thought by Frank contains all the complexity of Frank's situation, what Frank is doing is a sin in the eyes of the Catholic church, not only this Theresa is sick and dying.
