"Why was Monica going into the lantern room?" demanded Lindsay, the moment they were alone.
"Does she know the secret?" ventured Cicely.
"Either she knows, or she's trying to find out. Perhaps she's stalking Mrs. Wilson too!"
This was a new idea, and required consideration.
"Then that would perhaps be what 'The Griffin' was warning Scott about," said Cicely reflectively. "Ought we to tell Monica?"
"Not yet—not till we've something more definite to go upon. We've only suspicions at present, and one can hardly speak about those. She might be offended, and think us meddlesome, especially as she doesn't like to talk of her affairs."
"I'm afraid she'll think us sneaky and underhand, in any case. I'm so sorry she saw us spying like that."
"Well, we couldn't help it, and we can't explain."
"It's no use," interrupted Lindsay decidedly. "We'd better not breathe a word."
