Colonel Welsh turned and led them over to a desk so big that it could have easily been cut up into five desks of the usual size. Three men were seated at the desk, and they pushed up from their chairs as the Colonel and the two youths approached. "Captain Lamb," the Colonel said, pointing to a chunky redhead. "Next to him, Captain Stacey. And that chap who's as thin as I am is Lieutenant Caldwell, our coding expert. Gentlemen, Flight Lieutenants Dawson and Farmer." Dave and Freddy shook hands with the other officers, and then dropped into chairs the Colonel pulled up. It was not until then that Dave had an opportunity to take a good look about him, and what he saw set his blood to tingling through his veins, and his heart to pounding against his ribs. He had often been inside the inner offices of British Intelligence, and on each occasion he had been stunned by the number of gadgets of all sorts, and the vast array of equipment they were used to operate. But the stuff he stared at now put the British equipment in the shade. There was every conceivable piece of equipment from ultra-ray flashlights to giant X-ray machines. One whole wall was lined with telephones and short wave radios for both sending and receiving. And along another wall was a row of file cabinets that operated electrically. One had only to push a file button, and the correct drawer slid open and the exact file folder shot up out of its clamps. In truth, Dave believed that Colonel Welsh had at his fingertips complete information of everyone of importance in the war, and that within a matter of seconds he could establish contact with any one of his agents, no matter in what part of the globe he might be. And those two items were but two of the many, many things that could be made possible with the equipment in that huge room. It was like the mechanical wizardry of Scotland Yard and the F.B.I. all set up in the same room. "Interesting stuff, isn't it, Dawson?" Dave turned his head to see Colonel Welsh grinning at him. He blushed slightly, and nodded. "It certainly is, sir," he said politely. "A fellow could have some fun in this place." "Depends on what you call fun," the Intelligence officer said with a grimace. "There's been more than one death warrant issued from this place. However, you're not here to be taught how to handle this stuff. Matter of fact, though, I suppose you're wondering just why you are here, eh?" "Decidedly, sir!" Freddy Farmer fairly exploded the words. "And how!" Dave echoed. "If I don't find out something, and soon, I'm going to dive right out a window, and end it all. For three days, sir, Farmer and I have been living a crazy, cockeyed dream. Maybe it's a nightmare, I don't know. But if you can possibly give us an inkling what it's all about, then consider me down on my knees and begging you to do just that! Honest! I don't know whether I'm coming or going."
