"All dressed up in a Dominican habit and black gloves," said Charles. "I hardly think so. Take a look at the front door, Peter."

"Bolted, and the chain in position. I happened to notice. What about this window?"

Charles strode across to it, and flung back the curtains. "It's bolted - no, by Jove, it's not!" He turned to Bowers, who up till now had been a scared auditor. "Bowers, do you remember if you bolted this to-night?"

Bowers shook his head. "No, sir. At least, I don't think so. Begging your pardon, sir, but the mistress always likes it left open till you go up to bed. I thought you bolted it."

"That's right," Peter said. "And to-night we sat in the drawing-room. That's how it got forgotten. Cheer up, Aunt Lilian! What you saw was someone dressed up to give you a fright, and that's how he got in."

"No, my dear, you are wrong," Mrs. Bosanquet said firmly. "It had no need of doors or windows. For all we know it is still present, though now invisible."

Celia gave one moan of horror, and implored Charles to take her back to town at once.

"I think we'd all better go back to bed for the rest of the night, and discuss it in the morning," Charles said. "I don't see that we shall do much good trying to search the garden now. We'll bolt this window, though. And what about having Margaret to sleep in your room, Aunt? Would you prefer it?"

"Not at all," she replied. "If it re-appeared, Margaret would be of no assistance to me, or any of you. I shall go quietly up, and to sleep, for I feel I shall not see it again to-night."

On account of the night's disturbance breakfast was put back next morning for an hour, but contrary to everyone's expectations Mrs. Bosanquet was the first down. When Celia, Margaret, and Peter appeared they found her looking as placid as ever, and reading the morning paper. "Good morning, my dears," she said, laying the paper down. "I see there has been fresh trouble in China. I feel one has so much to be thankful for in not being Chinese."
