"I think so myself," agreed Nat.
It seemed quite a long time that Mr. Clayton and the detective were gone, and Nat grew impatient.
"Something must have happened," he said.
"I hope so," answered the pilot. "I hope they got him, and that he had your money with him."
They resumed their pacing up and down. About ten minutes later they saw Mr. Clayton and the officer coming toward them, unaccompanied.
"They didn't get him!" exclaimed Nat.
"Maybe he gave up the money."
"I hope he did. I shouldn't like to go to court over it."
"Well?" asked the pilot, as the two came nearer.
"We were just too late," answered Mr. Clayton dejectedly.
