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.

He was sorry for the pilot but it was not pity that made him circle lower and check the field toward which the Heinkel was spinning. Stan wanted to ask that Jerry a few questions, and the Jerry had to be rescued from his firetrap or he couldn't do it.

The Heinkel turned over, flattened and eased up, then plunged into a tangle of bushes beside a road. Stan gauged the rolling field which spread beside the road. He could have set a Hurricane down on that field easily, but a Spitfire was different. Her landing gear was high and narrow. He side-slipped and leveled off, then skimmed over the grass and bumped down, jerking and swaying. The Spitfire rolled up to within a safe distance from the burning plane and Stan leaped out.

The Jerry had almost made it out of the plane. He was draped over the side with his parachute harness caught in the smashed hatch cover. Risking an explosion which would have finished them both, Stan jerked the pilot loose and dragged him a safe distance from his ship. They were less than fifty feet from the Heinkel, when her tank cut loose and billows of smoke and flame rolled up, licking at the grass and brush.

The Heinkel's pilot sat on the grass. He watched his ship vanish and his face worked. If it had not been for the Royal Air Force pilot bending over him, he would at that moment be frying to a crisp. He shuddered and licked his lips.

Stan gave his attention to the fellow's wounds. He was badly hit in the shoulder and bleeding freely. His face was white.

"Who tipped you off that I'd be flying solo along this route?" Stan demanded.
