I'd never really focused on the opening sentance before and found the exercise quite interesting. Ranged from the tersely cogent e.g.
"Mark Sanderson liked women." Frederick Forsyth "No Comebacks"
to real stage set pieces e.g.
"All the efforts of several hundred thousand people, crowded in a small space, to disfigure the land on which they lived; all the stone they covered it with to keep it barren; how so diligently every sprouting blade of grass was removed; all the smoke of coal and naphtha; all the cutting down of trees and driving off of cattle could not shut out the spring, even from the city." Count Leo Tolstol "The Awakening"
A few others that reflect so much the style of the author:
"I believe this is the first English country house you have stayed at Miss Worsley?" Oscar Wilde. " A Woman of No Importance"
"The pebbled glass door panel is lettered in flaked black paint: "Philip Marlow...Investigations." Raymond Chandler "The Little Sister"
"At the hour of the hot spring sunset two citizens appeared at the Patriarch's Ponds." Mikhail Bulgakov. "The Master and Margarita."
"Hale knew they meant to murder him before he had been in Brighton three hours." Grahame Greene. "Brighton Rock"
"I am living at the Villa Borghese. There is not a crumb of dirt anywhere, nor a chair misplaced. We are all alone here and we are dead." (Sorry 3 sentances!) Henry Miller. "Tropic of Cancer."
"At five o'clock that morning reveille was sounded, as usual, by the blow of a hammer on a length of rail hanging up near the staff quarters." Alexander Solzhenitsyn. "A Day in the Life of Ivan Denisovich."
"I'm going to get that bloody bast-rd if I die in the attempt." James Clavell. "King Rat."
"We were in class when the head-master came in, followed by a "new fellow," not wearing the school uniform, and a school servant carrying a large desk." Gustave Flaubert 'Madame Bovary."
A new game. Try using one of the listed authors and adapt their individual style to write one of the above from an opening sentence not their own!
