ho 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

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

It would have been impossible for her to enter unobserved, so popular
was she. It was not long before the two girls whom Constance had seen
dealing with "Sleighbells" sauntered over.

"Your friend was here to-night," remarked one to Adele.

"Which one?" laughed Adele.

"The one who admired your dancing the other night and wanted to take
lessons."

"You mean the young fellow who was selling something?" asked Constance
pointedly.

"Oh, no," returned the girl quite casually. "That was Sleighbells," and
they all laughed.

Constance thought immediately of Drummond. "The other one, then," she
said, "the thick-set man who was all alone!"

"Yes; he went away afterward. Do you know him?"

"I've seen him somewhere," evaded Constance; "but I just can't quite
place him."
