"I told you about the window before, Miss," said Chalks, doggedly. "I let them doctors do what they liked, as it ain't my place to advise medical men. As to sitting up, Dr. Jerce told me to do so, but master insisted that I should leave about eleven, as usual. How can I obey them all?" asked the little man, tearfully. "I ask you that, Miss."

"But you knew the danger, and----"

"What danger, Miss? Master has slept with that window open, off and on, for three years--ever since Dr. Wentworth came to look after him. He said it was to be open, and Dr. Jerce always wanted it to be shut. I let them do what they liked."

"You should have remained all night with Mr. Horran," said Clarice, remembering that Chalks knew nothing about the warning of the Purple Fern, or the need of especial supervision.

"With a royal Bengal tiger, Miss?" wailed Chalks, "for that was what master was last night. I never saw him so cross--never. He seemed to have something on his mind, and went on awful."

"What did he say?" asked Miss Baird, thinking Horran's utterances might shed a light on the darkness.

"I can't tell you Miss. It was swearing for the most part. But he made me go to bed, and laughed when I declared that Dr. Jerce told me to sit up with him."

"How did you leave him?"

"Sitting up in bed, swearing."

"With that window open?"
