The second officer spoke. "Captain Pring is perfectly right, sir," he said modestly. "I'll swear that they had been public school or 'Varsity men at some time or other." "Where were you?" I asked quickly. "Harrow, sir." I nodded. Here was another astounding fact for consideration when I was alone. "And then, after a time," Pring continued, "the _Sant Iago_ tramp steamer freighter came up from way down South and rescued us. After that we sighted the lights of Mr. Van Adams' air yacht, the _May Flower_, and in answer to our signal he came down and took me and Rickaby aboard." "Quite," said the laconic millionaire. "To-night, Captain Pring, I shall want a long talk with you. Now I must surrender you to Sir Joshua. For the present, I want you all three to give me your words of honour that you will tell no one at all anything about the appearance or speed of the ship, that her engines were silent, or you suspect the ruffians on her to be English. That is most important. In fact, I must make it an order, under the powers with which I am invested by the Secretary of State. As an order, it cannot apply, to you, Mr. Van Adams, but you have been so kind and helpful hitherto that I feel sure you'll give me your promise? You must see how necessary it is." Mr. Van Adams was going to use his word-of-all-work, I saw it coming, when he changed his mind. "I'm on," he said instead. The two pilots gave me their assurances, and we walked out of the office together. As we went along the terrace Pring pointed down to the sea-drome, where the millionaire's air yacht, a beautiful boat, painted cream colour and black, was now resting at her moorings. "The _Atlantis_ starts to-night," he said significantly. "She will be escorted by an armed patrol," I said, "until she meets one of the American A.P. ships in mid-ocean. Surely, you don't think there's any danger?" To tell the truth, I had been so concentrated upon the matter in hand that I had hardly given a thought to the outgoing liner. Can you blame me? Anyway, duty came before any private considerations. Now, Pring's remark started a new set of thoughts. I looked at him with great anxiety. He did not know the whole of my reason, but he saw that I was disturbed. "No, Sir John," he answered, "I don't think the danger worth the waggle of a mule's ear. It was only a passing remark. It stands to reason that Captain Kidd'll know that the police boats of two hemispheres are out looking for him in swarms by now. He'll figure that out, sure. If he was to start any of his stunts within the next few days, he'd have about as much chance as a fat man in Fiji." "That's what I thought." "You may make your mind easy about the _Atlantis_, sir. Besides, as you say, to put the lid on, she'll be escorted." "Quite," I said involuntarily, and then we both laughed. "Royal Hotel at ten-thirty," I said. "I shall be staying there to-night."
