"Thew!" the purser repeated. "Now I tell you that I have definite suspicions of this man," Crawshay continued, "because I know that for some reason or other he hates England, although he has the appearance of being an Englishman. I know that he has been friendly with enemy agents in New York, and I know that he has been in recent communication with enemy headquarters at Washington. Therefore, as I say, I suspect Mr. Jocelyn Thew. I also suspect Robins, the wireless operator, because I am convinced that he has received messages of which he has taken no record. I now pass on to the remainder of my suspicions, for which I frankly admit that I have nothing but surmise. I suspect Mr. Phillips, Doctor Gant and Miss Katharine Beverley." The last shock proved too much for the captain. For the first time there was distinct incredulity in his face. "Look here, Mr. Crawshay," he protested, "supposing you are right, and that you are on the track of a conspiracy, how do you account for a physician from the finest hospital in New York and one of the best-known young ladies in America being mixed up in it?" Crawshay acknowledged the difficulties of the supposition. "As regards the physician," he said thoughtfully, "I must confess that I am without information concerning him, a fact which increases my suspicion of Robins, for I should have had his _dossier_, and also that of the man Phillips, by wireless twenty-four hours ago." "What about Miss Beverley then?" the captain enquired. "Her family is not only one of the oldest in America, but they are real Puritan, Anglo-Saxon stock, white through and through. She has a dozen relatives in Congress, who have all been working for war with Germany for the last two years. She also has, as she told me herself, a brother and four cousins fighting on the French front--the brother in the Canadian Flying Corps, and the cousins in the English Army." "There I must confess that you have me," Crawshay admitted. "What you say is perfectly true. That is one of the mysteries. No plot would be worth solving, you know, if it hadn't a few mysteries in it." "If you will allow me a word, Mr. Crawshay," the purser intervened, "I think you will have to leave Doctor Gant and his patient and Miss Beverley out of your speculations. I have our own ship doctor's word for it that Mr. Phillips' condition is exactly as has been stated. Mr. Jocelyn Thew may or may not be a suspicious character. Anything you suggest in the way of watching him can be done. But as regards the other three, I trust that you will not wish their comfort interfered with in any respect." "Beyond the search to which every one on board will have to be subjected," Crawshay replied, "I shall not interfere in any respect with the three people in question. Mr. Jocelyn Thew, however, is different. He is a man who has led a most adventurous life. He seems to have travelled in every part of the globe, wherever there was trouble brewing or a little fighting to be done."
