Ordinarily the second invitation would have given him something to busy himself with; but it happened that he was at that moment planning to do a heartbreaking thing without breaking any heart. Billy Larremore, the veteran whose devotion to polo was responsible for so many of the team's victories in the past, was not aware that age had bade him cease playing. It would break his loyal heart not to play in the forthcoming international match. Tom Merriwether had been delegated to break the news. Thinking about it made him forget all about the letter until the following Monday, when he received the third invitation: _Merriwether,--Come to 777 Fifth Avenue Tuesday morning at ten-thirty without fail and answer the question._ He crumpled the card and was about to throw it away when he changed his mind. Perhaps it would be wise to give it to a detective agency. But what could he say he feared? Then he decided it was probably a joke. Somebody wished to put him in the ridiculous position of ringing the bell of 777, showing the card--and being told to get out. It was to be regretted that this would seem funny to some of his perennially juvenile intimates at the Rivulet Club. An hour later, as he walked down the Avenue, he looked curiously at 777. It was one of those newcomer houses erected by speculative builders to sell furnished to out-of-town would-be climbers or to local stock-market bankers who, being Hebrews, were too sensible to wish to climb, but were not sensible enough not to wish to live on Fifth Avenue. Tom resolved to ask Raymond Silliman, who played at being in the real-estate business, to find out who lived at 777. Meantime he did a little shopping--wedding-presents--and went to luncheon at his club. He had not quite finished his coffee when he was summoned to the telephone. “Hello! Mr. Merriwether?” said a woman's voice--clear, sweet, and vibrant, but unknown. “This is Miss Hervey--the nurse--Dr. Leighton's trained nurse. They asked me to tell you about your father. Don't be alarmed!” “Go on!” commanded young Merriwether, sharply. “It is nothing serious--really! But if you could come home it probably--Yes, doctor! I am coming!” And the conversation ceased abruptly. Tom instantly left the club. He took the solitary taxicab that stood in front of the club. He afterward recalled the fact that there was only one where usually there were half a dozen. “Eight-sixty-nine Fifth Avenue. Go up Madison to Sixtieth and then turn into the Avenue. Hurry!” “Very good, sir,” said the chauffeur.
