"Forgot what?" Colonel Fraser demanded. "Come, come, Dawson! What the devil is this all about?" "This, sir," Dave said weakly, and fished a hand into his tunic pocket to pull out the little black leather book he had taken from the inside of Herr Baron's tunic lapel. "I felt it in his tunic lapel, sir," he said. "But I clean forgot to mention it. Here, sir. It's all in code, I think." Dawson held it out and Colonel Fraser practically pounced on it like a tiger upon a hunk of meat. He flipped through the pages rapidly, and the look in his eyes got brighter and brighter. "Praise the powers that be you didn't forget any longer than you did, Dawson!" he snapped. Then, with a quick shake of his hand, "I'm sorry for that, old man. I apologize. You went through enough to make a man to forget 'most everything. It's just that I'm so excited to get hold of this." "That's all right, sir," Dave said with a smile. "I should have thought of it sooner. You think you can break down that code?" "With ease," the colonel said, and reached out a hand to press one of a row of buttons on the edge of his desk. "It's one of the numbers codes. The Nazis go all out for that type of code, for some unknown reason. Naturally, though, we're grateful to them for that, because they are so simple to break down. I remember once when--" But the side door opened to admit a rather tired-eyed lieutenant, and the colonel didn't continue. He turned and handed the little black book to the officer. "Get everything out of this, Wilson," he said. "Put two or three on it, if you have to. I want it as soon as possible. By the way, anything yet on the other business?" "Yes, sir," the lieutenant said. "I was about to ring you when you buzzed. Henderson just called in. Both John Dobbler and Harold Cabot are listed in Records as having been killed during the blitz. Neither has been seen at the address given since then, sir. Fact is, sir, Henderson says Dobbler's block was completely destroyed, and nothing's been put up there as yet." "Thank you, Wilson," Colonel Fraser said with a nod of dismissal. "Now, get right at that thing, there's a good chap." "Quite, sir," the junior officer said, and hurried out of the office. Colonel Fraser turned to the other and clenched his fists in a helpless gesture. "If only we could devise some means of civilian identification that couldn't be stolen by Nazi scoundrels!" he said bitterly. "No doubt that Hans and that Erich have been walking around London bold as brass and posing as poor Dobbler and Cabot ever since the Blitz! It's enough to make a man weep." "I wonder how they got hold of the papers." Dawson murmured.
