"A key ring, with two keys on it."

"Where did you find it?"

"Here, right beside the pool."

"Then somebody has been here and taken our fish!"

"Exactly what I believe."

Jack began to examine the key ring and then he uttered another exclamation:

"Here are some initials on the ring."

"What are they?"

"I can't make out very well—they are so worn. I think the first is R."

"Let me see."
