The most welcome sound in all the world drowned out Dawson's voice at that moment: the powerful, thunderous roar of the B-Twenty-Five's twin Wright Cyclones coming to life. For a few precious seconds Dawson let them roar so that they would warm up as fast as possible. But at the end of that time he saw spitting flame off to the left and ahead, and the left side window of the pilots' compartment seemed to blow in on him in a shower of splintered glass.

"Get going, Dave!" Freddy Farmer cried excitedly.

"Get, nothing!" Dawson roared back. "We're gone!"

And even as the first word spilled off his lips he had kicked off the wheel brakes, forked the throttles wide open and was booting the B-Twenty-Five around the necessary half-turn to get it headed toward the far end of the field. And then as the bomber went forward, picking up speed with every powerful revolution of its propellers, orange, red, and yellow flame sparked and stabbed the darkness on both sides. Dawson felt bullets smash into the bomber, and even heard some of them twang off the engine cowlings, but the twin Cyclones did not miss a single beat, and the B-Twenty-Five went thundering forward until the wings could get their teeth in the air, and Dawson was able to lift the ship clear and nose it upward into the stormy night.

When no more than a couple of thousand feet were under his wings, he leveled off, checked with the automatic compass, and then swung the B-Twenty-Five around toward the north.

"Back to your job of navigating, Freddy, old sock!" he shouted at his pal. "Moscow next stop, and we're in a hurry. So you see to it that we hit it on the nose, hey, kid?"

"Have I ever missed?" Freddy snapped at him.

"Well, anyway," Dawson grinned back at him, "see that you don't make this the first time!"

Clear, brilliant sunshine flooded the length and breadth of Moscow. Four wonderful days Dawson, Agent Jones, and Freddy Farmer had spent in the fascinating Soviet city. Four swell days of sight-seeing, and banquets for heroes—themselves. Though the three of them had insisted that the major share of the glory belonged to Senior Lieutenant Petrovski, who had as quickly disappeared out of their lives as she had come into them.

As a matter of fact, five minutes after Dawson had landed the B-Twenty-Five on the Moscow military airport, the pretty-looking Russian girl was gone, just like that. And Colonel General Vladimir, who was at the airport to greet them, had explained in a few words, with a meaningful smile.
