He was furiously angry.  He reeled the engine back along its shaft and went circling up.  He saw Ostrog’s machine beating up a spiral before him.  He rose straight towards it, won above it by virtue of the impetus of his swoop and by the advantage and weight of a man.  He dropped headlong—­dropped and missed again!  As he rushed past he saw the face of Ostrog’s aeronaut confident and cool and in Ostrog’s attitude a wincing resolution.  Ostrog was looking steadfastly away from him—­to the south.  He realized with a gleam of wrath how bungling his flight must be.  Below he saw the Croydon hills.  He jerked upward and once more he gained on his enemy.

He glanced over his shoulder and his attention was arrested.  The eastward stage, the one on Shooter’s Hill, appeared to lift; a flash changing to a tall grey shape, a cowled figure of smoke and dust, jerked into the air.  For a moment this cowled figure stood motionless, dropping huge masses of metal from its shoulders, and then it began to uncoil a dense head of smoke.  The people had blown it up, aeroplane and all!  As suddenly a second flash and grey shape sprang up from the Norwood stage.  And even as he stared at this came a dead report; and the air wave of the first explosion struck him.  He was flung up and sideways.

For a moment his monoplane fell nearly edgewise with her nose down, and seemed to hesitate whether to overset altogether.  He stood on his wind-shield, wrenching the wheel that swayed up over his head.  And then the shock of the second explosion took his machine sideways.

He found himself clinging to one of the ribs of his machine, and the air was blowing past him and upward.  He seemed to be hanging quite still in the air, with the wind blowing up past him.  It occurred to him that he was falling.  Then he was sure that he was falling.  He could not look down.

He found himself recapitulating with incredible swiftness all that had happened since his awakening, the days of doubt, the days of Empire, and at last the tumultuous discovery of Ostrog’s calculated treachery.

The vision had a quality of utter unreality.  Who was he?  Why was he holding so tightly with his hands?  Why could he not let go?  In such a fall as this countless dreams have ended.  But in a moment he would wake....

His thoughts ran swifter and swifter.  He wondered if he should see Helen again.  It seemed so unreasonable that he should not see her again.  It must be a dream!  Yet surely he would meet her.  She at least was real.  She was real.  He would wake and meet her.

Although he could not look at it, he was suddenly aware that the earth was very near.

THE END.
