ouglas rose as his orderly, Ranth, came into the room. "Find Lieutenant Praed for me," the colonel ordered crisply. Then, turning to Lance, he said: "You'd better knock off a few hours' sleep. You are worn out."

Lance watched the orderly, Ranth, salute and leave. Ranth was heavy, thick-built, with closely set eyes. The young squadron leader was suddenly conscious that he was, as the colonel said, worn out; his limbs seemed leaden, his eyelids heavy. "I think you're right, sir," he murmured, and walked out onto the field.

Seeing Praed's machine drawn up with the overall-clad figure of a mechanic fussing at its motors, he wandered over to survey it. The scout was an exact replica of his, a model of the famous Goshawk type. It was all motor—everything being sacrificed to speed. On either side of the stubby brow of the fuselage, which held the death-dealing battery of three machine-guns, were set the four Rahl-Diesel motors, back to back. The pilot's tiny enclosed cockpit was thus surrounded by engines. In the V-shaped, smooth-lined wings were the two helicopter props; further back, inside the steel-sheathed, bullet-like fuselage, the radio outfit and fuel tanks. The craft's rounded belly covered the gas bomb compartment.

The mechanic was a little cockney Englishman, a fugitive, like all his countrymen, from the horror which had stricken England suddenly and left her wallowing in her life blood. He looked up at Lance, and a smile broke forth on his wizened, sharp little face.

"It's got me beat, sir," he said in his curious, twanging voice. "Lieutenant Praed, 'e sez to me, 'Somethin' wrong with two of me motors,' 'e sez. 'They quit on me quite sudden like. Look 'em over, will you?' 'e sez. So I been lookin' 'em over. But they ain't nothin' wrong with the bloody things, sir—nothin' at all!"

"It does seem funny, doesn't it, Wells?" Lance said levelly. He'd known it all along. Praed was a quitter—a yellow-belly—besides being—But he stopped there. He had no definite proof. It was unjust to accuse a man of that without definite, positive proof.

The little mechanic muttered some mysterious cockney curse, and then said, in an admiring tone:

"'Ow many of the swines' planes 'ave you shot down now, sir?"

"About twenty, I think," Lance told him gruffly. The cockney shot his breath out with a whistle.
