But Miss Payne's physical condition desolated him. If she was so obviously exhausted at 12.30, what would she be like at the day's end?' 'I've got it!' he cried. He seized a pen and wrote: 'Notice.--The public are respectfully informed that this establishment will close to-day at two o'clock.' He rang a bell, and a messenger appeared. 'Take this to the printing-office instantly, and tell Mr. Waugh it must be posted throughout the place in half an hour.' Shortly after two o'clock Sloane Street was amazed to witness the exodus of the three thousand odd. The closure was attributed to a whim of Hugo's for celebrating some obscure anniversary in his life. Many hundreds of persons were inconvenienced, and the internal economy of scores of polite homes seriously deranged. The evening papers found a paragraph. And Hugo lost perhaps a hundred and fifty pounds net. But Hugo was happy, and he was expectant. At ten o'clock that night a youngish man, extremely like Simon Shawn, was brought by Simon into Hugo's presence under the dome. This was Simon's brother, Albert Shawn, a member of Hugo's private detective force. 'Sit down,' said Hugo. 'Well?' 'I reckon you've heard, sir,' Albert Shawn began impassively, 'the yarn that's going all round the stores.' 'I have not.' 'Everyone's whispering,' said Albert Shawn, gazing carefully at his boots, 'that Mr. Hugo has taken a kind of a fancy to Miss Payne.' Hugo restrained himself. 'Heavens!' he exclaimed, with a clever affectation of lightness, 'what next? I've only spoken to the chit once.' 'Don't I know it, sir!' 'Enough of that! What have you to report?' 'Miss Payne left at 2.15, whipped round to the flats entrance, took the lift to the top-floor, went into Mr. Francis Tudor's flat.' 'What's that you say? Whose flat?' cried Hugo. 'Mr. Francis Tudor's, sir.' Mr. Tudor was famous as the tenant of the suite rented at two thousand a year; he had a reputation for being artistic, sybaritic, and something in the inner ring of the City. 'Ah!' said Hugo. 'Perhaps she is a friend of one of Mr. Tudor's--' 'Servants,' he was about to say, but the idea of Miss Payne being on terms of equality with a menial was not pleasant to him, and he stopped. 'No, sir,' said Albert Shawn, unmoved. 'She is not, because Mr. Tudor shunted out all his servants soon afterwards. Miss Payne was shown into his study. She had her tea there, and her dinner. The Hugo half-guinea dinner was ordered late by telephone for two persons, and rushed up at eight o'clock.' 'I wonder Mr. Tudor didn't order an orchestra with the dinner,' said Hugo grimly. It was a sublime effort on his part to be his natural self. 'I waited for Miss Payne to leave,' continued Albert Shawn. 'That's why I'm so late.' 'And what time did she leave?' 'She hasn't left,' said Albert Shawn. CHAPTER IV CAMILLA Hugo dismissed Albert, with orders to continue his vigil, and then he rang for Simon. 'Do you think I might have some tea?' he asked.
