An alien sound obtruded suddenly into the throbbing of his Spitfire. He heard it almost without consciousness of what it portended, then was abruptly aware that a stream of bullets was ripping through his fuselage.

A Heinkel had slid up behind him from nowhere and its smoking guns were streaming hot, leaden death at him. For a moment he was too amazed to properly meet this unexpected danger. He had a curious feeling that it was after him. That it wasn’t merely a stray enemy plane making chance contact. It was an absurd thought, but it gripped him strongly and he couldn’t shake it off.

Another burst of lead hosed from the Heinkel. Stan rolled the Spitfire to the left, then pulled it up tight and hard. The Heinkel shot under him, went into a loop, then faked a turnover. Stan smiled grimly.

“That won’t fool me, son,” he muttered. He leveled off fast and eased over into a three hundred yard safety zone. Setting the Spit on her ear, he faced the Heinkel, testing his Brownings as he slid into place.

The Jerry was a crack flier. The Heinkel came in with a roaring thrust, her Madsen slugs drilling away at the Spitfire. Stan heard the stingers zipping through his fuselage. A blue flame began playing up and down over a hole in his fuel tank.

“Well,” Stan muttered sourly. “I’ll have to put a stop to this, or else——”

He sent the Spitfire off to the right like a streak. The Heinkel zoomed past, building altitude for a death thrust. Stan cracked the throttle wide open and kicked in the emergency booster. The Merlin answered splendidly.

Glancing into his mirror he took in the setup, then faked a steep climb. Up he went, 500 feet, then sent the Spitfire into a screaming back-over roll, holding his ship upside down until he was behind the Heinkel and above it. Then he dropped the Spitfire as though she were crippled. This placed him under the Heinkel and he went up. The Jerry was now trying to make a run for it. Stan saw a spread of fuselage and a wing through his windscreen and he pressed the gun button. The Brownings spat fire and lead. The Jerry was trapped and knew it. He swayed and rocked and twisted in an attempt to get away. The bullets drilled out again, a four-second burst.

Fire and smoke rolled out of the port motor. The flames licked in around the stricken ship. A rancid whiff came to Stan and reminded him that his own fuel tank was on fire. It would be only a matter of seconds until he would be in a flaming coffin himself.

The Merlin was still hitting beautifully. Stan squirmed about and jerked loose a fire extinguisher. He turned the handle and pumped frantically. The liquid spray feathered out and blanketed the fire. Stan sucked in a deep breath and looked down at the plummeting Heinkel. The Jerry was trying to bail out, but he wasn’t making much headway. Stan nosed down and watched the struggle.
