Curiosity began to stir within him. He wondered if by judicious probing he could penetrate the wall of aloofness with which his companion seemed to be surrounded. It would be interesting to know if the fellow really possessed any individuality. Airily he broke the silence. "Are you going to take me straight into the temple of the sun? I thought I was out to see the fishing." The remote blue eyes came back as it were out of the far distance and found him. There came to Knight an odd, wholly unwonted, sensation of smallness. He felt curiously like a pigmy disturbing the meditations of a giant. Rufus looked at him for several seconds of uninterrupted rowing before, in his deep, resounding voice, he spoke. "They won't be taking up the nets for a goodish while yet. We shall be back in time." "The idea is to give me a run for my money first, eh?" inquired Knight pleasantly. He had not anticipated the sudden fall of the red brows that greeted his words. He felt as if he had inadvertently trodden upon a match. "No," said Rufus slowly, speaking with a strangely careful accent, as if his mind were concentrated upon being absolutely intelligible to his listener. "That was not my idea." The spirit of adventure awoke in Knight. There was something behind this granite calmness of demeanour then. He determined to draw it forth, even though he struck further sparks in the process. "No?" he said carelessly. "Then why this pleasure trip? Did you bring me out here just to show me--the 'Pit of the Burning'?" His eyes were upon the dazzling glory of the newly risen sun as he threw the question. Rufus's massive head and shoulders were strongly outlined against it. He had ceased to row, but the boat still shot forward, impelled by the last powerful sweep of the oars, the water streaming past in a rush of foam. Slowly, like the hammer-strokes of a deep-toned bell, came Rufus's voice in answer. "It wasn't to show you anything I brought you here. It was just to tell you something." "Really?" Knight's interest was thoroughly aroused. He became alert to the finger-tips. There was something in the deliberate utterance that conveyed a sense of danger. A wary gleam shone in his eyes under their level brows. It was one of his principles when dealing with an uncertain situation never to betray surprise. "And what may this valuable piece of information be?" he inquired, with a smile. Rufus shipped his oars steadily, gravely, with purpose. "I saw you cross the quicksand last night," he said. "Indeed!" Knight's voice was of the most casual quality. He was feeling for his cigarette-case. Rufus continued heavily, fatefully, gathering force with every word, as a loosened rock beginning to roll down a mountain side. "The light was bad. It was a tomfool thing to do. And Columbine was with you." Knight raised his shoulders ever so slightly. "Or rather--I was with her. Miss Columbine knows the lie of the quicksand. I--do not."
