"Madge Frettlby is not the woman to scream and waken a somnambulist," said Calton, decidedly, "knowing as she did the danger. There must be some other reason."

"This young woman will tell you all about it," said Chinston, nodding towards Sal, who entered the room at this moment. "She was present, and since then has managed things admirably; and now I must go," he said, shaking hands with Calton and Fitzgerald. "Keep up your heart, my boy; I'll pull her through yet."

After the doctor had gone, Calton turned sharply to Sal Rawlins, who stood waiting to be addressed.

"Well," he said briskly, "can you tell us what startled Miss Frettlby?"

"I can, sir," she answered quietly. "I was in the drawing-room when Mr. Frettlby died—but—we had better go up to the study."

"Why?" asked Calton, in surprise, as he and Fitzgerald followed her up stairs.

"Because, sir," she said, when they had entered the study and she had locked the door, "I don't want any one but yourselves to know what I tell you."

"More mystery," muttered Calton, as he glanced at Brian, and took his seat at the escritoire.

"Mr. Frettlby went to bed early last night," said Sal, calmly, "and Miss Madge and I were talking together in the drawing-room, when he entered, walking in his sleep, and carrying some papers—"

Both Calton and Fitzgerald started, and the latter grew pale.
