Jack laughed. “Well, does Mr. Grey look like a maniac?” he asked.

Paul smiled and remarked, “Well, he does look rather odd, tall and thin as he is.”

“All that doesn’t get us anywhere,” said Jack.

“Well, let’s not come to any conclusions but wait until Mr. Grey comes,” remarked Paul.

“Yes, he’ll clear it all up for us.”
