"That's war, I guess," Dave murmured sympathetically. "And the same thing has happened in other countries, sir. It isn't going to help any to take it too hard, you know. Anyway, the rat is dead, and the leak is plugged up. That's something, at least."

"But mighty little!" the Colonel said bitterly. Then, stabbing a finger at the window facing the harbor, he grated, "There's the Indian out there. In an hour she weighs anchor. Aboard her is the most dangerous rat of all. He possesses information that could well mean the difference between victory and defeat if it falls into Jap hands. We can't hold the Indian. She's got to sail. Without her the whole battle plan is mixed up. Yet if she sails and we don't catch that scoundrel, who knows what will happen? I had hoped, but—well, now that's all shot, too."

"What's all shot, sir?" Dave asked quickly.

"The job I had planned for you and Farmer aboard the Indian," the Colonel replied. "It was a wild hope even at best, but now it isn't even that. The rats know why I wanted you two aboard her. True, maybe the man you're after doesn't know. I've a feeling, though, he does. The way things have gone, I feel certain they got word to him somehow. If they did, he'd know exactly why you were there the moment you came over the side. And—well, to put it bluntly, he's killed twice already. Twice more wouldn't bother him if he suspected you were getting close to him. He'd—"

"We can watch our step," Dave cut in grimly.

"Too great a risk," the Colonel replied. "You see, it wouldn't be a matter of your actually getting close, but the matter of his thinking that you were close. He'd know who you were, and why you were aboard. The advantage would be all his. It would be unfair to ask any man to tackle a job like that."

"I don't fancy so, sir," Freddy Farmer spoke up quietly. "After all, rats usually do have all the advantage until you get them cornered. Supposing he does know why we're there? Let him, I say. It's a job to be done, and somebody's got to tackle it, sir. Good grief! If somebody doesn't go after the blighter, it's like letting the Indian sail with a lighted fuse leading to her powder magazine."

"I check on that, too, sir!" Dave cried eagerly. "Freddy and I aren't trying to toot our horns, Colonel. Maybe we'll fall flat on our faces. But maybe we won't. However, at least we'll be aboard in case something does turn up that gives us a clue."

"Yes, of course," the Colonel grunted, and frowned. "That's quite true. But you could be throwing your lives away—and uselessly, too. You two helped accomplish something almost as big today, perhaps even bigger. I can't say yet. But capturing those two American born rats was a mighty big step toward smashing a lot of the Fifth Column business in this country. I mean that, too. That place was one of their arsenals where they've cached guns to be used when Berlin sends the order to strike at the United States from within. It's one of several arsenals located about the country. Those papers contained names and addresses of key men in their organization. And right now some of my agents, and F.B.I. agents, are waiting in that shack for the so-called big boss. His capture alone will be something mighty big. Yes, you two played a major part today in nipping something big in the bud. So it isn't fair to ask you to—"

"Okay, okay!" Dave suddenly snapped. "If you don't think we rate a crack at it, then have the Indian sail without us. I'm willing to take the chance. So's Freddy. But if you think we'd mess up things, then skip it. Let it slide."
