Brandon of the Engineers by Harold Bindloss

Shortly after the launch entered the lagoon, the Danish boat hove her anchor and steamed out to sea. Dick, who had engaged a half-breed pilot to take the launch home, lounged in a canvas chair under the poop awning. His eyes were half closed, for the white boats and deckhouses flashed dazzlingly in the strong light as the steamer lurched across the vivid swell of the Caribbean. The cigarette he languidly held had gone out, and his pose was slack.

He was physically tired and his brain was dull, but he was conscious of lethargic satisfaction. For a long time he had been torn between his love for Clare and his duty to his country. His difficulties were further complicated by doubts of Kenwardine's guilt, but recent events had cleared these up. It was, on the whole, a relief to feel that he must now go forward and there need be no more hesitation and balancing of probabilities. The time for that had gone and his course was plain. He must confront Kenwardine with a concise statement of his share in the plot and force from him an undertaking that he would abandon his traitorous work.
