Freddy laughed, and in half a minute had Dave free. As he pulled the last rope loose, he stepped quickly backward and set himself for the expected rush. But Dave simply rubbed his hands and wrists and glared at him.

"Relax!" he growled. "I'm going to save this one up, you betcha! And when the right time comes, will you sing a song and dance a dance for me! Kidding aside, though, Freddy, that was something. I really mean it. Boy! Can you always come up with something new! But don't think that means I'm going to forget, you little bum. My turn will come."

Freddy grinned at him impishly, and then both stopped their horse play and turned serious eyes toward the Colonel.

"We can still make San Diego with time to spare, sir," Dave said with a glance at his watch. "Are we going to take those two along with us?"

"We certainly are," the Colonel said, and pointed a finger at the pilot. "That one is just ripe to be cracked wide open. He'll blab everything he knows to save his own neck. I've met his type often. Hard as nails on the surface, but completely yellow underneath."

"It's pretty hard to believe that a couple of Americans would stoop this low," Dave said, tight-lipped. "But I suppose the Axis has a fifth column working here in the States just as they had in every other country they tackled."

"True enough," the Colonel replied with a nod. "And as the saying goes, some men will sell their souls for gold. Those two are the type. Country and flag don't mean a thing to them. Something twisted inside of them. They weren't put together right in the first place. But this is a big thing for my bureau, boys! And for the F.B.I., too. I have a hunch I know who their big boss is—a man the F.B.I.'s been after for weeks. There'll be a welcoming committee waiting for him tonight. Have no fear of that. Before we get going, however, I want to have a quick look around here. Give me a hand. Maybe we'll find something of importance. We've got an hour or so, haven't we?"

"Easy," Dave replied. "Shall we hunt for something special?"

"Hunt for anything!" the Colonel said grimly. "And pray for a miracle find."

Exactly one hour and six minutes later they had finished going over the room with fine tooth comb thoroughness. The net result was a batch of papers that the Colonel clutched in his hand. A couple of them had lists of names and addresses. The others were covered with messages that were all in code, and couldn't be broken down right at the moment. The Colonel was pleased with the results, but there was just the slightest gleam of disappointment in his eyes. Dave saw the gleam and wondered.
