" A grey tide, engulfing all colour and shape of things that had been or were to be, rushed across his mind, sweeping the life out of everything and leaving him all hollow inside. Once again he sat benumbed in a shadow show. Yet as ever—and this was the cruel stroke—there was something left, left to see that all the lights were being quenched, left to cry out with a tiny crazed voice in the grey wastes. This was what mattered, this was the worst, and black nights and storms and floods and crumbling hills were not to be compared with this treachery from within. It wasn’t panic nor despair, he told himself, that made so many fellows commit suicide; it was this recurring mood, draining the colour out of life and stuffing one’s mouth with ashes. One crashing bullet and there wasn’t even anything left to remember what had come and gone, to cry in the mind’s dark hollow; life could then cheat as it liked, for it did not matter; you had won the last poor trick. Having conjured the malady into a phrase or two, Penderel felt better, came out of his reverie and looked about for entertainment. "
