"Got what?" Freddy demanded.

"The solution to the whole works!" Dave said. "It all depends on nailing down that Nazi mechanic before he can let out a peep. Darn! If we only had a gun!"

"We have," was Freddy Farmer's startling reply. "I thought you saw me, Dave. Before we left Ox Face I took his Luger out of its holster. Here it is, now, right in my hand."

Dave touched the smooth metal gun Freddy thrust at him, and chuckled inwardly.

"Pal, do you think of everything!" he breathed. "What would I do without you!"

"Make a blasted mess of things, no doubt!" Freddy hissed in his ear. "But, what's your plan? What were you going to say?"

"Two Messerschmitt One-Nines, and those hand grenades that guy has!" Dave said. "We gag and tie up that Nazi. Then we take off in a One-Nine apiece. Then we tear for those camouflaged glider hangars and let fly with the hand grenades. Their explosions will touch off that TNT, and the whole works will go sky high."

"Us, too, I fancy," Freddy Farmer murmured.

Dave swallowed hard and nodded.

"Yeah, probably, Freddy," he said and pressed the other's arm. "We'll have plenty of company, though, so what the heck? But wait, Freddy! I got a better idea. We don't have to fly too low over that drained swamp to toss the grenades overboard. First we get plenty of altitude, and then let the things go. A couple of them are bound to hit, and two will be plenty. That's a pretty fair sized area, and hard to miss."
