Bubbles opened her eyes.

"I'll come up after dinner for a few minutes," said Dr. Panton. Bubbles made no answer; her eyes were now following Varick out of the door.

The doctor lingered for a moment. "You're sure there was someone there?" he asked.

"Of course I'm sure." Bubbles spoke quite positively. "I'm sure"—and then he saw a change come over her face—"and yet I don't know that I am quite sure," she murmured dreamily.

As Dr. Panton went down the shallow oak staircase he felt in a turmoil of doubt and discomfort. To his mind there was no reasonable doubt that Miss Pigchalke had somehow effected an entrance to Wyndfell Hall. She had lived there for long years; she must know every corner of the strange old house.

When he reached the hall where the whole party was gathered together, he went up to Blanche Farrow. "May I speak to you a moment?" he whispered.

"What is it?" she asked anxiously. "Isn't Bubbles so well?"

"Oh, yes; Miss Bubbles is going on all right. But, Miss Farrow? I want to tell you something that, if possible, I should like to keep from Varick."

"Yes—what is it?"

"Someone who has a grudge against him, a tiresome old woman who was companion to Mrs. Varick for many years, has somehow got into this house. She spoke to me just as I came out of my room. I didn't see her, but I heard her voice quite distinctly. And when Varick and I went into Miss Bubbles' room for a moment, on our way downstairs, she followed us in—Miss Bubbles described her exactly. Then suddenly she disappeared. I am sure she's hiding in one of the bedrooms."
