Meanwhile, instinctively, Eleanor was trying on the hat before the long mirror set in the door of the closet. She admitted to herself that she looked astonishingly well in it. She was a sane and sensible young woman, who knew that she was exceedingly good looking and was glad of it in the same wholesome way that she was glad she had a good singing voice. Very probably the hat was more of a piece with the somewhat flamboyant if unimpeachable loveliness of Alison Landis; but it would seem hard to find a hat better suited to set off the handsome, tall and slightly pale girl that confronted Eleanor in the mirror. It seemed surprisingly heavy, even for a hat of its tremendous size. She was of the opinion that it would make her head ache to wear it for many hours at a time. She was puzzled by its weight and speculated vaguely about it until, lifting it carefully off, her fingers encountered something hard, heavy and unyielding between the lining and the crown. After that it didn't take her long to discover that the lining had been ripped open and resewn with every indication of careless haste. Human curiosity did the rest. Within a very few minutes the Cadogan collar lay in her hands and she was marvelling over it--and hazily surmising the truth: Staff had been used as a blind agent to get the pearls into the country duty-free. Quick thoughts ran riot in Eleanor's mind. Alison Landis would certainly not delay longer than a few hours before demanding her hat of Mr. Staff. The substitution would then be discovered and she, Eleanor Searle, would fall under suspicion--at least, unless she took immediate steps to restore the jewels. She acted hastily, on impulse. One minute she was at the telephone, ordering a taxicab, the next she was hurriedly dressing herself in a tailor-made suit. The hour was late, but not too late--although (this gave her pause) it might be too late before she could reach Staff's rooms. She had much better telephone him she was coming. Of course he would have a telephone--everybody has, in New York. Consultation of the directory confirmed this assumption, giving her both his address and his telephone number. But before she could call up, her cab was announced. Nevertheless she delayed long enough to warn him hastily of her coming. Then she snatched up the necklace, dropped it into her handbag, replaced the hat in its bandbox and ran for the elevator.
