The Green Door offers O. Henry's clever story about fate, romanticism and finding the right "door of opportunity." In the story, a young salesman taking an evening stroll in New York City is handed a card which bears the mysterious handwritten words "The Green Door." Guided by the spirit of adventure, he finds a green door to an apartment in a dimly-lit hallway. His knock is answered by a girl living in extreme poverty. Before the evening is over, he comes to believe it was fate that brought them together.
O. Henry's short stories are well known for their wit, wordplay, warm characterization and clever twist endings.
