Apparently she now had found the place in the book which, more or less mechanically, she had been seeking. She turned down the upper corner of a certain page for a marker and closed the book.

"Well, in any event," she said, "I must get to work. I think I shall begin by calling up my cousin to tell her, among other things, that her party may have some rather unique features that she had not included in her program. And where can I reach you by telephone or by messenger—say, in an hour from now?"

A number of small things, seemingly in no wise related to the main issue, occurred that evening and on the following morning. In the evening, for example, Mrs. Hadley-Smith revised the schedule of amusements she had planned for her All Fools' party, incorporating some entirely new notions into the original scheme. In the morning Miss Mildred Smith visited the handkerchief counter of a leading department store, where she made selections and purchases from the stocks, going thence to a shop dealing in harness and leather goods. Here she gave a special commission for immediate execution.

Toward dusk of the evening of April first a smallish unobtrusive-looking citizen procured admittance to Mrs. Hadley-Smith's home, on East Sixty-third Street just off Fifth Avenue. With the air of a man having business on the premises he walked through the front door along with a group of helpers from the caterer's. Once inside, he sent a name by the butler to Mrs. Hadley-Smith, who apparently awaited such word, for promptly she came downstairs and personally escorted the man to a small study at the back of the first floor; wherein, having been left alone, he first locked the door leading to the hall and drew the curtains of the windows giving upon a rear courtyard, and proceeded to make himself quite at home.

He ate a cold supper which he found spread upon a table and after that he used the telephone rather extensively. This done, he lit a cigar and stretched himself upon a sofa, smoking away with the air of a man who has finished his share of a given undertaking and may take his ease until the time arrives for renewed action upon his part. Along toward nine-thirty o'clock, when he had smoked his third cigar, there came a soft knock thrice repeated upon the door, whereupon he rose and unlocked the door, but without opening it to see who might be outside he went back to his couch, lay down and lit a fourth cigar. For the next little while we may leave him there to his comfortable solitude and his smoke haze.

Meanwhile the Hon. Sidney Bertram Goldsborough, so called and so registered at the Hotel Atminster, grew decidedly peevish over the unaccountable failure of his order to arrive from a theatrical costumer's, where he had selected it some three days earlier. He was morally sure it had been sent hours earlier by special messenger from the costume shop. In answer to his vexed inquiries the parcels department of the hotel was equally sure that no box or package consigned to Mr. Goldsborough had been received. Finally, after ten o'clock, the missing costume was brought to the gentleman's door with a message of profound regret from the assistant manager, who expressed sorrow that through the stupidity of some member or members of his force a valued guest had been inconvenienced. Hastily slipping into the costume and putting a light overcoat on over it Mr. Goldsborough started in a taxicab up Fifth Avenue. But at Forty-eighth Street a government mail van, issuing suddenly out of the sideway, smashed squarely into the side of the taxicab bearing him, with the result that the taxi lost a wheel and Mr. Goldsborough lost another half hour.

This second delay was due to the fact that his presence upon the spot was required by a plain-clothes man who took over the investigation of the collision from the patrolman on the post. To Mr. Goldsborough, inwardly fuming but outwardly calm and indifferent, it seemed that the plain-clothes person took an unreasonably long time for his inquiries touching on the accident. At length, with apologies for detaining him, the headquarters man—now suddenly become accommodating where before he had been officially exact and painstaking in his inquisition into causes and circumstances—personally hailed another taxicab for Mr. Goldsborough and sent him upon his way.

But, Mr. Goldsborough's chapter of petty troubles was not yet ended; for the driver of the second taxi stupidly drove to the wrong address, landing his fare at a house on West Sixty-third Street, clear across Central Park and nearly halfway across town from Mrs. Hadley-Smith's home. So, what with first one thing and then another, eleven o'clock had come and gone before the indignant passenger finally was set down at his proper destination.

We go back to nine-thirty, which was the hour set and appointed for inaugurating the All Fools' Day party. Nine-thirty being the hour, very few of the prospective celebrants arrived before ten. But by ten, or a little later, most of them were assembled in the big twin drawing-rooms on the first floor of the Hadley-Smith establishment. These two rooms, with the study behind them and the wide reception hall that ran alongside them, took up the most of the first-floor ground space of the town house. As the first arrivals noted, they had been stripped of furniture for dancing. One room was quite empty, save for decorations; the other contained only a table piled with favours. Even the chairs had been removed, leaving clear spaces along the walls.

It was not such a very large party as parties go, for Mrs. Hadley-Smith had a reputation for doing her entertaining on a small but an exceedingly smart scale. All told, there were not more than fifty on hand—and accounted for—by ten o'clock. A good many had come in costume—as zanies, Pantaloons, witches, Pierrots, Columbines, clowns and simples. For those who wore evening dress the hostess had provided a store of dunce caps and dominos of gay colours. Nearly everybody present already knew nearly everybody else. There were only five or six guests from out of town, and of these Mme. Josephine Ybanca, wife of the great South American diplomat, and Miss Evelyn Ballister, sister of the distinguished Western statesman, were by odds the handsomest. Of women there were more than men; there usually are more women than men in evidence at such affairs.
