the left, leading down to the Admiralty.  There he paused for a moment, and, turning around, listened intently.  He was possessed of particularly keen hearing and it seemed to him as though from afar off he could hear the sound of a thousand muffled hammers beating upon an anvil; of a strange, methodical disturbance in the air.  He grasped the railing with one hand and gazed upward with straining eyes.  Just at that moment he saw distinctly what appeared to be a flash of lightning in the sky, followed by a report which sounded like a sharp clap of thunder.  Then instinctively he covered his eyes with his hands.  From a dozen places—­one close at hand—­a long, level stream of light seemed to shoot out towards the clouds.  There was one of them which came from near the Carlton Hotel, which lit up the whole of the Pall Mall Arch with startling distinctness, gave him a sudden vision of the Admiralty roof, and, as he followed it up, brought a cry to his lips.  Far away, beyond even the limits of the quivering line of light, there was something in the sky which seemed a little blacker than the cloud.  Even while he looked at it, from the Admiralty roof came a lurid flash, the hiss and screech of a shell as it dashed upwards.  And then the sleeping city seemed suddenly to awake and the night to become hideous.  Not fifty yards away from him something fell in the Park, and all around him lumps of gravel and clods of earth fell in a shower.  A great elm tree fell crashing into the railings close by his side.  Then there was a deafening explosion, the thunder of falling masonry, and a house by the side of the arch broke suddenly into flames.  A few moments later, a queer sight amongst all these untoward and unexpected happenings, a fire engine dashed under the arch, narrowly missing the broken fragments of brick and stone, swung around, and a dozen fire-hoses commenced to play upon the flaming building.

The darkness was over now, and the silence.  There were houses on the other side of the river on fire, and scarcely a moment passed without the crash of a falling bomb.  The air for a second or two was filled with piteous shrieks from somewhere towards Charing-Cross, shrieks drowned almost immediately by another tremendous explosion from further north.  Every now and then, looking upwards in the line of the long searchlights, Thomson could distinctly see the shape of one of the circling airships.  Once the light flashed downwards, and between him and Buckingham Palace he saw a great aeroplane coming head foremost down, heard it strike the ground with a tremendous crash, heard the long death cry, a cry which was more like a sob, of the men who perished with it. . . .

Every moment the uproar became more deafening.  From all sorts of unsuspected places and buildings came the lightning quiver of the guns, followed by the shrieking of the shells.  Right on to the tops of the houses between where he was standing and the Carlton, another aeroplane fell, smashing the chimneys and the windows and hanging there like a gigantic black bat.  There was not a soul anywhere near him, but by the occasional flashes of light Thomson could see soldiers and hurrying people in the Admiralty Square, and along the Strand he could hear the patter of footsteps upon the pavement.  But he himself remained alone, a silent, spellbound, fascinated witness of this epic of slaughter and ruin.
