Dave whistled softly, then stared hard at the Intelligence chief.

"But is that such a big loss, sir?" he asked. "Those plans, I mean. Can't they be changed, so that even if the Japs have them it won't make any difference?"

Colonel Welsh sighed heavily and shook his head.

"I certainly wish they could be changed," he said presently. "I wish it were as easy as that. But, unfortunately, it isn't. The Indian's plans are just part of a huge plan to knock a good big hole in the Jap naval and air forces in that part of the Southwest Pacific. And an attack on that scale can't be thought up overnight, and put into execution the next morning. It's not simply a question of rushing ships and planes to a certain spot and banging away until you're out of shells and bombs. There's much, much more than that. Your forces must be split up. Your operation timetable must be worked out so that the slower ships will arrive at the same time as the fast ones. Worked out so that certain groups will have mine sweeping and destroyer protection. Worked out so that there will be a covering force in case parts of any unit are forced out of action and must retire. No, Dawson, it's not that simple. There are a hundred and one things to be worked out, so that you stand the maximum chance of the entire operation being carried out like clockwork. So it follows that if one unit is off whack, other units are bound to suffer. The effectiveness of the striking force is reduced. For that matter, effectiveness is reduced all down the line. And at the snap of the fingers you can barge bow-on straight into serious trouble. No, to change the Indian's plans would mean that we'd have to change and alter the entire plan as a whole. And there is the chance that in doing that we would discover that it would be best to give up the whole project."

"Phew, I never dreamed a navy show was that complicated!" Freddy Farmer breathed. "But I say, sir! If the blasted Japs know the part the Indian's unit is to play, what can you do about it but change everything, or else give it up entirely."

"I didn't say the Japs had the plans for the Indian's unit," the Intelligence chief said. "Maybe I misled you. I said that the plans are lost. They were stolen from Commander Jackson and Lieutenant Commander Pollard. They had the only copies of the plans, as they were to be in complete charge of the Indian's fighters and bombers in this action. Those plans they carried on their person at all times. And when they were last seen they were on their way below to the hangar deck to check a new gun sight that is to be tried in this coming engagement. They were seen to reach the hangar deck by the Watch Officer. The next time they were seen, they were dead and about to be burned beyond recognition by flaming high test gasoline. But for a machinist's mate who happened to pass that part of the hangar deck, they would have been burned beyond recognition. And we would never have known that their copies of the plans were stolen. True, we would have discovered that they were murdered, shot, just as we did discover. And we might have suspected that the killer had stolen the plans. But now we know that somebody aboard the Indian has those plans."

"Huh?" Dave gulped. "Somebody aboard her? You mean, right now?"

"I mean right now," the chief of U. S. Intelligence said grimly. "The Indian was at anchor in San Diego Harbor. She's still there. However, the instant it was realized what had happened, the Indian became an isolated ship. Not a man, not even her captain, was allowed to go ashore. I radioed those orders myself. And not a boat of any type was permitted to come so much as within hailing distance. An order was issued to shoot anybody who attempted to leave the Indian, and to shoot anybody who attempted to approach the Indian. That order still stands. Mighty hard on the chaps who were due shore leave—she hadn't been in port more than a day. But we're not taking chances."

Colonel Welsh paused for breath, and Dave nodded his head slowly.

"I get it," he said. "So far no darn Jap has got his hands on those plans. No real Jap, I mean."
