Life would go out in a 'fraction of a second' (that was the phrase), but all night he had been realizing that time depends on clocks and the passage of light. There were no clocks and the light wouldn't change. Nobody really knew how long a second of pain could be. It might last a whole purgatory--or for ever.

Regular as clockwork the old excuses came back into the alert, sad and dissatisfied brain--nothing ever matched the deep excitement of the regular desire. Men always failed you when it came to the act. She might just as well have been to the pictures.
Graham Greene
