Uneasy Money by P. G. Wodehouse

In the interesting land of India, where snakes abound and scorpions are common objects of the wayside, a native who has had the misfortune to be bitten by one of the latter pursues an admirably commonsense plan. He does not stop to lament, nor does he hang about analyzing his emotions. He runs and runs and runs, and keeps on running until he has worked the poison out of his system. Not until then does he attempt introspection.

Lord Dawlish, though ignorant of this fact, pursued almost identically the same policy. He did not run on leaving Lady Wetherby's house, but he took a very long and very rapid walk, than which in times of stress there are few things of greater medicinal value to the human mind. To increase the similarity, he was conscious of a curious sense of being poisoned. He felt stifled -- in want of air.
