Daunt ran to a low door in the long garage. The key was on a ring in his pocket. He went in, locking the door behind him. There were no electric lights—he had been there heretofore only by day—and the carriage lamps made only a subdued glimmer that was reflected from the polished metal of the great winged thing resting on its carrier. He threw off his evening coat and set feverishly to work. After its single trial the new fan-propeller had been unshipped for a slight alteration, and the flanges had not yet been reassembled. There were delicate adjustments to be made, wire rigging to be tautened, a score of minute tests before all could be safe and sure. He worked swiftly and with concentration, feeling his mind answering to the stress with an absolute coolness.

At length the last attachment was in place, the final bolt sent home and one of the lamps lashed close in the angle of the wind screen. He took his place and the engine started its familiar double rhythm: pst-pst—pst-pst—pst-pst, as the explosive drop fell faster and faster. He leaned and broke the clutch which held the big double doors of the building. They swung open and he threw on the gear.

And suddenly, as the propeller began to spin, in the instant the Glider started in its rush down the guides, Daunt was aware that some one had darted through the doors. He had a flashing view of a white, disheveled face, heard a cry behind him—then the prow of the Glider tilted abruptly, the air whistled past the screens, the great flat field sank away, and he was throbbing steeply upward, against the sweep of the wind.

Daunt threw himself forward—the bubble in the spirit-level clung to the top of its tube. Rapidly he warped down the elevation-vanes till slowly, slowly, the telltale bubble crept to the middle of the level. What was the matter? The engine was working well, yet there was a sense of heaviness, of sluggishness that was unaccountable. He looked to either side, before him, behind him.

His fingers tightened on the clutches. Just forward of the whirling propeller he made out the figure of a man, lying flat along the ribs of the Glider's body, clutching the steel guys of the planes, looking at him.

For a moment he stared motionless. It was this extra weight that had sent the Glider reeling prow-up—had made it unresponsive to control. The man who clung there had aimed to prevent the flight! Daunt leaned to let the full beam of the flaring lamp go past him. A quick intuition had told him whose were the eyes that had glittered across the throbbing fabric; but the face he saw now was infuriate with a new look that made him shiver. It was incarnate with the daredevil of terror. Phil had been a drunkard; he was drunk now with the calculate madness of overmastering fear. As he gazed, a flitting, irrelevant memory crossed Daunt's mind, of a day at college, years before, when by a personal appeal, he had saved Phil from the disgrace of expulsion. And now it was Phil—Phil!—clinging there, with desperate, hooked fingers, struggling to consummate a crime that must sink him for ever!

Pst-pst—pst-pst—pst-pst; on the Glider drove. With a fierce effort, Daunt crushed down the sense of unreality and swiftly weighed his position.

The other was directly in front of the propeller, a perilous place. Only the guy-wire was in his reach. Between them was a shuddering space. To land in the darkness to rid the aëroplane of that incubus, was impossible. He must go on. Could he win with such a terrible handicap? He set his teeth. Tilting the lateral vanes, he soared in a wide serpentine, peering into the deep, resounding dark below.

Tokyo lay a vast network of tiny pin-pricks of fire. He had never been so high before, had been content to sweep the tree-tops. To the left a bearded scimitar of light, merged by blackness, marked the bay. Daunt swung parallel with this. Pst-pst—pst-pst—pst-pst. The wind tore in gusts through the structure, the planes vibrating, the guys humming like the strings of a gigantic harp. His clothing dragged at his body. He was too high; he leaned over the mass of levers and the Glider slid down a long, steep descent, till in the starlight he could see the blue-gray blur of roofs, the massed shadows of little parks of trees. Now he was passing the edge of the city—now below him was the gloom of the rice-fields. A low sobbing sound came in the wind; it was the bubbling chorus of the frogs, and across it he heard the bark of a peasant's dog.

To the right a dark hill loomed without warning, with a dim congeries of red tea-houses. It was the famous Ikegami, the shrine of the Buddhist saint Ichiren, famed for its plum-gardens. It fell away behind, and now, far off, a score of miles ahead, grew up on the horizon a misty blotch of radiance. Yokohama! He swerved, heading out across the lagoon, straight as the bee flies for the shimmering spot. Pst-pst—pst-pst—faster and faster spat the tiny explosions. The Glider throbbed and sang like a thing alive, and the hum of the propeller shrilled into a scream.
