“Well, that clears up so much of the mystery,” said Joe. “But it looks as if Hanleigh is up against it just as much as we were. We know the secret of the cipher message and it didn’t do us any good.”

“Perhaps he knows something else. Sparewell may have given him further instructions in that sealed envelope.”

Frank looked through the other papers he had taken from Hanleigh’s pocket. He was interrupted by a sudden whisper from Biff.

“Be careful!”

“What’s the matter?”

“He’s waking up.”

Frank thrust the papers back into the coat pocket. There would be trouble when Hanleigh learned how he had been tricked. Then Biff sighed with relief.

“False alarm. He turned over again. He’s still asleep.”

Frank went back to the papers, relieved. He searched through them carefully. But he did not find what he sought. There were no further references to the cipher, to the sealed envelope, or to John Sparewell.

“Nothing else here,” he reported finally.
