“Maybe some one came in from outside——”

“No, we were as silent as death itself. We would have heard a window or door open. There was no sound whatever, was there, Natalie?”

“No. Spirits make no sound.”

The girl was still in a half-dazed state. Almost in a trance she was, even now, or, rather, she appeared so.

“I can’t stand it,” she said. “I feel giddy. I’ll go to my room.”

She went away, and the two other women stood, looking at each other.

“It must have been Natalie,” said Joyce, reluctantly. “You see, she did know where the jewels were and got them out of some hiding-place when I ran up to your room.”

“But how could she turn off the lights?”

“I don’t know, unless she has an accomplice among the servants. Sometimes I think Blake——”

“No, Joyce, don’t implicate Blake. I feel sure he is entirely innocent. Did you hear that voice clearly?”
