As to the doctor, he suddenly turned very white again, and muttered shakingly: “Can it be? I don’t exceed as others do. I swear I have taken less this month than ever before.”

With the terror in his soul he stumbled toward the door and was moving out his hand to reach it, when it opened from the other side and Zyp, as meek and pure looking as a young saint, met him on the threshold.

Now, I had that morning, in the course of conversation with the changeling, touched upon Dr. Crackenthorpe and his weaknesses, and that ghostly mention of the bottle convinced me on the moment that only she could be responsible for the mystery—a revelation of impishness which, I need not say, delighted me. The method of her prank I may as well describe here. The embrasure for a fireplace in her room had never been fitted with a grate, and the hearthstone itself was cracked and dislocated in a dozen places. By removing some of these fragments she had actually discovered a broken way into the chimney of the sitting room below, down which it was easy to slip a hollow rail of iron which with other lumber lay in the attic. This she had done, listened for her opportunity, and thereupon spoken the ominous words.

I think her appearance was the consummation of the doctor’s terror, for a shuddering “Oh!” shook from his lips, and he seemed about to drop. And indeed she was somewhat like a spirit, with her wild white face looking from a tangle of pheasant-brown hair and her solemn eyes like water glints in little wells of shadow.

She walked past the stricken man all stately, and then Modred and I jumped up and greeted her. At this the doctor’s jaw dropped, but his trembling ceased and he watched us with injected eyes. Holding my two hands, Zyp looked coyly round, leaning backward.

“I love a tall man,” she whispered; “he has more in him than a short one.”

The doctor pulled himself together and came straggling across to the table.

“Who the pestilence is this?” he said, in a voice not yet quite under his command.

Zyp let go my hands and curtsied like a wild flower.

“Zyp, the orphan, good gentleman,” she said; “shall I fill your pipe for you?”
