"It is part of the scheme," he said. "Part of my scheme, you understand.

CHAPTER XVI
MARGARET SEES A GHOST
With a sigh of unutterable relief Enid heard Williams returning. Reginald Henson had not come down yet, and the rest of the servants had retired some time. Williams came up with a request as to whether he could do anything more before he went to bed.
"Just one thing," said Enid. "The good dogs have done their work well to-night, but they have not quite finished. Find Rollo for me, and bring him here quick. Then you can shut up the house, and I will see that Mr. Henson is made comfortable after his fright."
The big dog came presently and followed Enid timidly upstairs. Apparently the great black-muzzled brute had been there before, as evidently he knew he was doing wrong.
