"Hope you did the thing thoroughly while you were about it! Garret to cellar and all the rest?"

"You bet we did," returned the policeman, allowing himself the relief of a grin now. "I guess you was right about the practical joke. But you must excuse us if we look behind these curtains."

"Under the table, too!" laughed Logan, jumping to his feet. "Stand and deliver, Rolls!"

Petro obeyed rather reluctantly, feeling that he had been made a fool of, at best, in his stupid wish to be good-natured. It might be a joke, as Logan insisted, but something told him it was not. The look on the fellow's face as he gulped down the champagne cup had not been funny. It was in Petro's mind that he had been brought in to cover up with his presence an unpleasant incident and ignorantly to trick the police.

Of course, if there were a girl in the house, the police would have found her. But—there was something queer. He meant to have it all out with Logan when the police were gone. Meantime, however, he behaved loyally and stood up to leave the table clear while one of the detectives did actually bend down to peer under it. As the policeman stooped Peter mechanically pulled the chair back, and

doing so he caught sight of a thin blue streak lying, like solidified cigarette smoke, across the red brocade cushion. In this smoke-blue streak there were little things that glistened—little silver things shaped like crescent moons set at regular intervals from each other. Peter had been unconsciously sitting on the smoke wreath, and as the policeman rose he deliberately sat down on it again. He felt suddenly sick, and his heart was large and cold in his breast, where it did not beat, but floundered like a caught fish.

[CHAPTER XXII]

THE FRAGRANCE OF FRESIAS

Winifred Child had been in this house, or else she had sold or given the Moon dress to another girl who had been here.

Thoughts were flashing through Peter's brain with the sharp quickness of motion pictures following one another to a far conclusion. Of the girl he could not be sure. The lost dryad, needing money more than she needed a smart evening gown, might well have disposed of Ena's gift. And yet Petro had—strangely enough it had seemed to him then—thought of Winifred and the mysterious "dryad door" on the Monarchic the moment he came into this place.
