Dunbar and the commissario had put a long distance between themselves and the estancia house now. The silence of the hot night settled down with its palpable mysterious weight upon the earth. The stars looked farther away than usual in the fathomless vault of heaven, and the world slumbered with a feeling of restlessness under the burden of the aching solitude of the night. Some insects chirped outside the illuminated window-pane, as though they would fain have left the large and solitary splendour without and sought company in the humble room. Time passed noiselessly, undisturbed even by the ticking of a clock. To have stirred in a chair would have seemed to break some tangible spell. A dog would have been better company than a man at the moment, because less influenced by the mysterious night and the silence, and the intensity of thought which fixed itself relentlessly in some particular cells of the brain until they became fevered and ached horribly. A little puff of cooler air began to blow over the baked and withered camp; but the room where the lamp was burning had become intolerably hot, and the mosquitoes which had been contemplating the wall thoughtfully throughout the day began to buzz about and to sing in the ears of the two persons who sat there. 'Damn these mosquitoes!' said Peter, and his voice broke the silence of the lonely house oddly. He and Toffy had not spoken since Ross had left the room, and had not stirred from their chairs; but now the feeling of tension seemed to be broken. Toffy began to fidget with some things on a little table, and opened without thinking a carved cedar-wood work-box which had remained undisturbed until then. He found inside it a little knitted silk sock only half-finished, and with the knitting needles still in it, and he closed the lid of the box again softly. Peter walked into the corridor and looked out at the silver night. There was a mist rising down by the river, and the feeling of coolness in the air increased. He leaned against the wooden framework of the wire-netting and laid his head on his hands for a moment; then he came back to the drawing-room. 'Do you believe it?' he said suddenly and sharply. 'I suppose it's true,' said Toffy. 'God help us, Peter, this is a queer world!'
