Watching the whole proceeding from the window of the plane, Linda drew a deep sigh of relief. Then suddenly she remembered the third member of the gang—the man nick-named "Doc." Where was he? Hiding in the background, waiting to shoot them all down when they were off guard?
Cautiously, therefore, Linda leaned out of the side of the plane and called to Sergeant Worth to come back to her. Leaving the two thieves in charge of the other men, who instantly handcuffed them, Worth returned to the airplane, smiling over his easy victory.
With his assistance Linda jumped out of the cabin and whispered her warning into his ear. The man scowled in disappointment.
"This fellow may be waiting for you, Miss Carlton," he said. "You stay right here—behind the plane, while I go find out where he is."
Linda did as she was told, expecting every moment to hear renewed shooting.
"Where's your other man?" she heard Worth shout, as he approached the prisoners.
"Gone!" snarled Jake. "Two of 'em sneaked off. Double-crossed us, and took the kale!"
"Money? What money?" demanded Worth, instantly, hoping to surprise the man into a confession.
"Nothin'. None of your business," muttered Jake, seeing that he had made a mistake by saying too much.
"You needn't try to hide anything," remarked the officer, contemptuously. "We know all about the bank robbery—and other jobs, too—that you fellows can account for. You'll serve plenty of time!"
