“We’re going straight to the mansion,” she announced impressively.

Cara threw up her hands in a gesture of hopeless despair and stopped dead in her tracks.

“Another brilliant idea! I see it coming on. Remember, you told me to choke you if you ever had one again!”

Madge laughed.

“This idea is different and it doesn’t involve any digging. It’s worse than that. I’m afraid Miss Swenster won’t consent. You must help me convince her.”

In spite of herself, Cara’s curiosity was aroused.

“Convince her of what?”

“Come on,” Madge ordered, catching her by the hand and pulling her along. “There isn’t time to explain now. You’ll hear everything when we reach the mansion.”

Miss Swenster received them with her usual cordiality. Madge was so excited that as she plumped herself down on the sofa, it was difficult for her to begin. Briefly, she reviewed the facts already known to Miss Swenster and Cara, then disclosed the new notation she had found in the diary. She was a little disappointed to observe that neither appeared greatly impressed.

“I don’t see just what you have in mind,” Miss Swenster confessed.
