"I have been most confoundedly insulted by those d---- Germans," he said to Mr. Sabin, meeting him a little later in the gangway. "I don't know exactly what your position may be, but you will have to be on your guard. They have gone on to New York, and I suppose they will try and get their warrant endorsed there before we land." "They have a warrant, then?" Mr. Sabin remarked. "They showed me something of the sort," the captain answered scornfully. "And it is signed by the Kaiser. But, of course, here it isn't worth the paper it is written on, and America would never give you up without a special extradition treaty." Mr. Sabin smiled. He had calculated all the chances nicely, and a volume of international law was lying at that moment in his state-room face downwards. "I think," he said, "that I am quite safe from arrest, but at the same time, Captain, I am very sorry to be such a troublesome passenger to you." The captain shrugged his shoulders. "Oh, it is not your fault," he said; "but I have made up my mind about one thing. I am not going to stop my ship this side of Boston Harbour for anything afloat. We have lost half a day already." "If the Cunard Company will send me the extra coal bill," Mr. Sabin said, "I will pay it cheerfully, for I am afraid that both stoppages have been on my account." "Bosh!" The Captain, who was moving away, stopped short. "You had nothing to do with these New Yorkers and their broken-down yacht." Mr. Sabin finished lighting a cigarette which he had taken from his case, and, passing his arm through the captain's, drew him a little further away from the gangway. "I'm afraid I had," he said. "As a matter of fact they are not New Yorkers, and they are not husband and wife. They are simply agents in the pay of the German secret police." "What, spies!" the captain exclaimed. Mr. Sabin nodded. "Exactly!" The captain was still incredulous. "Do you mean to tell me," he exclaimed, "that charming little woman is not an American at all?--that she is a fraud?" "There isn't a shadow of a doubt about it," Mr. Sabin replied. "They have both tacitly admitted it. As a matter of fact I am in treaty now to buy them over. They were on the point of accepting my terms when these fellows boarded us. Whether they will do so now I cannot tell. I saw that fellow Graisheim talking to the man just before they left the vessel." "You are safe while you are on my ship, Mr. Sabin," the captain said firmly. "I shall watch that fellow Watson closely, and if he gives me the least chance, I will have him put in irons. Confound the man and his plausible----" They were interrupted by the deck steward, who came with a message from Mrs. Watson. She was making tea on deck--might she have the loan of the captain's table, and would they come? The captain gave the necessary assent, but was on the point of declining the invitation. "I don't want to go near the people," he said.
