Arthur Conan Doyle knew that. He was a writer of great beginning and great endings. This is true even in his short stories. My favorite first and last paragraphs come from the opening the same story, "His Last Bow."
It was nine o'clock at night upon the second of August -- the most terrible August in the history of the world. One might have thought already that God's curse hung heavy over a degenerate world, for there was an awesome hush and a feeling of vague expectancy in the sultry and stagnant air. The sun had long set, but one blood-red gash like an open wound lay low in the distant west. Above, the stars were shining brightly, and below, the lights of the shipping glimmered in the bay. The two famous Germans stood beside the stone parapet of the garden walk, with the long, low, heavily gabled house behind them, and they looked down upon the broad sweep of the beach at the foot of the great chalk cliff in which Von Bork, like some wandering eagle, had perched himself four years before. They stood with their heads close together, talking in low, confidential tones. From below the two glowing ends of their cigars might have been the smouldering eyes of some malignant fiend looking down in the darkness.
The ending, which I memorized as a boy:
The two friends chatted in intimate converse for a few minutes, recalling once again the days of the past, while their prisoner vainly wriggled to undo the bonds that held him. As they turned to the car Holmes pointed back to the moonlit sea and shook a thoughtful head.
“There’s an east wind coming, Watson.”
“I think not, Holmes. It is very warm.”
"Good old Watson! You are the one fixed point in a changing age. There's an east wind coming all the same, such a wind as never blew on England yet. It will be cold and bitter, Watson, and a good many of us may wither before its blast. But it's God's own wind none the less, and a cleaner, better, stronger land will lie in the sunshine when the storm has cleared. Start her up, Watson, for it's time that we were on our way. I have a check for five hundred pounds which should be cashed early, for the drawer is quite capable of stopping it if he can.”
Some would argue that the last sentence spoils the moment, and perhaps they are right.
