A few weeks after this incident, and whilst the two were at breakfast, the old village postman stumbled up the path leading to their house, and Jenkins, a sombre, morose man of few words, brought in a big official envelope. "What did I say, old chap?" cried Helston excitedly, tearing it open. "Didn’t I say my luck would change? Hullo! this isn’t an ordinary appointment. Whatever is it?" A large number of papers fell on the table, and, the Doctor showing some signs of interest, the two men hurriedly examined them, Jenkins standing behind at attention in order to learn the news. The first one was from the Admiralty, informing Helston that the enclosures had been received through the Chinese Embassy, and ordering him to report himself at Whitehall immediately. These enclosures were lists of ships supposed to be wrecked on the Chinese coast during the last few years, lists of Chinese men-of-war supposed to have been destroyed during the Chino-Japanese war, and papers showing the gradual rise in insurance rates for the Chinese coasting trade. "Where’s your appointment?" sneered the Doctor. "I’m off to see my patients." "I’ve got it, Doc; look here! Do you remember that old mandarin we got out of a scrape at Cheefoo once? Well, here’s a letter from him. Listen!" Saying which, Helston sat on the table and read it aloud, whilst the Doctor filled his pipe impatiently:— "DEAR COMMANDER HELSTON,—Perhaps you remember saving my life at Cheefoo many years ago? Now perhaps I can do you a good turn. "For the last three or four years there has been a very large number of steamers, ships, and junks employed on the coast trade which have left port under favourable circumstances and apparently in good condition, yet have never been heard of since. The number has rapidly become so great, that myself and several friends interested in the shipping trade have suspected that these disappearances were not due to natural causes. This year, for instance, three of our newest steamers have left Nagasaki full of valuable cargo, and, though none of them could have experienced bad weather, yet none have been heard of since. All three, strangely enough, carried a large quantity of military stores for Pekin, which had been transhipped from German steamers, and all three left within three weeks. The captains were Englishmen—very good men, too—and what adds to the peculiarity of their disappearance is, that the captain of the English mail-steamer which followed the last out of harbour, and should have passed her eight hours later if she had been on her proper course, never sighted her. We searched the coast ineffectually for any trace of wreckage, and it is only within the last two months that we have obtained a clue.
