"Mr Tench went out to look for his ether cylinder, into the blazing Mexican sun and the bleaching dust. A few vultures looked down from the roof with shabby indifference: he wasn't carrion yet. A faint feeling of rebellion stirred in Mr Tench's heart, and he wrenched up a piece of the road with splintering finger-nails and tossed it feebly towards them. One rose and flapped across the town: over the tiny plaza, over the bust of an ex-president, ex-general, ex-human being, over the two stalls which sold mineral water, towards the river and the sea. It wouldn't find anything there: the sharks looked after the carrion on that side. Mr Tench went on across the plaza.
"He said 'Beunos dias' to a man with a gun who sat in a small patch of shade against a wall. But it wasn't like England: the man said nothing at all, just stared malevolently."
-- Graham Greene, The Power and the Glory
