Katharine came on deck that morning in a somewhat disturbed frame of mind. It was beginning to dawn upon her that her position as sick nurse to Mr. Phillips was meant to be a sinecure. She was allowed to sit by the sick man's side sometimes whilst the doctor took a promenade or ate a meal in the saloon, but apart from that, the usual exercise of her duties was not required from her. She was forced to admit that there was something mysterious about the little stateroom, the suffering man, and the doctor who watched him speechlessly night and day. She was conscious presently that Crawshay, who had been walking up and down the deck, had stopped before the chair on which she lay extended. She greeted him without enthusiasm. "Are you taking one of your health constitutionals, Mr. Crawshay?" she enquired. "Not altogether," he replied. "May I sit down for a moment?" "Of course! I don't think any one sits in that chair." He took his place by her side, deliberately removed his muffler and unfastened his overcoat. It struck her, from the first moment she heard his voice, that his manner was somehow altered. She was altogether unprepared, however, for the almost stern directness of his first question. "Miss Beverley," he began, "will you allow me to ask you how long you have known Mr. Jocelyn Thew?" She turned her head towards him and remained speechless for a moment. It seemed to her that she was looking into the face of a stranger. The little droop of the mouth had gone. The half-vacuous, half-bored expression had given place to something altogether new. The lines of his face had all tightened up, his eyes were hard and bright. She found herself quite unable to answer him in the manner she had intended. "Are you asking me that question seriously, Mr. Crawshay?" "I am," he assured her. "I have grave reasons for asking it." "I am afraid that I do not understand you," she replied stiffly. "You must change your attitude, if you please, Miss Beverley," Crawshay persisted. "Believe me, I am not trying to be impertinent. I am asking a question the necessity for which I am in a position to justify." "You bewilder me!" she exclaimed. "That is simply because you looked upon me as a different sort of person. To tell you the truth, I should very much have preferred that you continued to look upon me as a different sort of person during this voyage, but I cannot see my way clear to keep silence on this one point. I wish to inform you, if you do not know it already, that Mr. Jocelyn Thew is a dangerous person for you to know, or for you to be associated with in any shape or form." She would have risen to her feet but he stopped her. "Please look at me," he begged. She obeyed, half against her will. "I want you to ask yourself," he went on, "whether you do not believe that I am your well-wisher. What I am saying to you, I am saying to save you from a position which later on you might bitterly regret."
