"Where does he get the stuff!" she asked.

The waiter shrugged his shoulders. "Nobody knows, I guess. I don't. But he gets it in spite of the law and peddles it. Oh, it's all adulterated—with some white stuff, I don't know what, and the price they charge is outrageous. They must make an ounce retail at five or six times the cost. Oh, you can bet that some one who is at the top is making a pile of money out of that graft, all right."

He said it not with any air of righteous indignation, but with a certain envy.

Constance was thinking the thing over in her mind. Where did the "coke" come from? The "grapevine" system interested her.

"Sleighbells" seemed to have disposed of all the "coke" he had brought with him. As the last packet went, he rose slowly, and shuffled out. Constance, who knew that Adele would not come for some time, determined to follow him. She rose quietly and, under cover of a party going out, managed to disappear without, as far as she knew, letting Drummond catch a glimpse of her. This would not only employ her time, but it was better to avoid Drummond as far as possible, at present, too, she felt.

At a distance of about half a block she followed the curiously shuffling figure. He crossed the avenue, turned and went uptown, turned again, and, before she knew it, disappeared in a drug store. She had been so engrossed in following the lobbygow that it was with a start that she realized that he had entered Muller's.

What did it all mean? Was the druggist, Muller, the man higher up? She recalled suddenly her own experience of the afternoon. Had Muller tried to palm off something on her? The more she thought of it the more sure she was that the powders she had taken had been doped.

Slowly, turning the matter over in her mind, she returned to the Mayfair. As she peered in cautiously before entering she saw that Drummond had gone. Adele had not come in yet, and she went in and sat down again in her old place.

Perhaps half an hour later, outside, she heard a car drive up with a furious rattle of gears. She looked out of the window and, as far as she could determine in the shadows, it was Dr. Price. A woman got out, Adele. For a moment she stopped to talk, then Dr. Price waved a gay good-bye and was off. All she could catch was a hasty, "No; I don't think I'd better come in to-night," from him.

As Adele entered the Mayfair she glanced about, caught sight of Constance and came and sat down by her.
