Cashel Byron's Profession by George Bernard Shaw

One morning a handsome young man, elegantly dressed, presented himself at Downing Street, and asked to see Mr. Lucian Webber. He declined to send in a card, and desired to be announced simply as "Bashville. " Lucian ordered him to be admitted at once, and, when he entered, nodded amiably to him and invited him to sit down.

"I thank you, sir," said Bashville, seating himself. It struck Lucian then, from a certain strung-up resolution in his visitor's manner, that he had come on some business of his own, and not, as he had taken for granted, with a message from his mistress.
