I go to London and see the busy multitudes in Fleet Street and the Strand, and it comes across my mind that they are but the ghosts of the past, haunting the streets that I have seen silent and wretched, going to and fro, phantasms in a dead city, the mockery of life in a galvanised body. And strange, too, it is to stand on Primrose Hill, as I did but a day before writing this last chapter, to see the great province of houses, dim and blue through the haze of the smoke and mist, vanishing at last into the vague lower sky, to see the people walking to and fro among the flower beds on the hill, to see the sight-seers about the Martian machine that stands there still, to hear the tumult of playing children, and to recall the time when I saw it all bright and clear-cut, hard and silent, under the dawn of that last great day. . . .
And strangest of all is it to hold my wife’s hand again, and to think that I have counted her, and that she has counted me, among the dead.

Pretty good early Brit Sci-Fi. (You used to be able to see it on YouTube, but I can’t find it now.)
