[EXPLAINS THE MYSTERY OF THE "TARIFA'S" CARGO]

"At St. Mary's," he continued, "I called at once upon the doctor. 'Ah,' said he, 'liver, I suppose.'

"'Permanently enlarged by excessive indulgence in alcohol,' said I. 'I had once a very dear friend in the same case called Ralph Warriner.'"

Here Miranda interrupted with considerable indignation. "There is not a word of truth in that."

"There is not," Wilbraham agreed pleasantly; "but I had to introduce the subject some way, and my way was successful. 'Ralph Warriner!' exclaimed the doctor. 'And what was he dismissed the service for?' I winked very slowly, with intense cunning; 'I understand,' said the doctor, with a leer, though Heaven only knows what he did understand; I fancy he thought his reputation as a man of the world was at stake. After that the conversation went on swimmingly.

"I was more than ever convinced that the discovery on Rosevear was a put-up job. If so, old man Fournier must have been aware of that wreck before he discovered it. He must have landed on the island and shoved those papers into the dead man's pocket; and someone must have sailed him out to the island. I determined to lay myself out to discover who that someone was; but I went no farther than the determination. There was not indeed any need that I should, for I sailed myself the next day to Rosevear. I hired the St. Agnes lugger, and Zebedee Isaacs, as he sat at the tiller, gave me news of old man Fournier. Old man Fournier was a desperate coward on the sea, yet he had put out to the Bishop on a most unpleasing day. It was old man Fournier who insisted that they should run through the Neck and examine Rosevear, and when Zebedee Isaacs declined the risk, old man Fournier flung himself in a passion on the tiller and nearly swamped the boat. All very queer, eh? M. Fournier must have had some fairly strong motive to nerve him to that pitch of audacity. And what that motive was I should discover when I discovered the nature of the Tarifa's cargo. I thought perpetually about that cargo, all the way to Rosevear, and after I had landed on that melancholy island. The truth came upon me in a moment of inspiration. The ground I remember gave way under my foot. I had trodden on a sea-bird's nest and stumbled forward on my knees, and with the shock of the stumble came the inspiration. I remained on my knees, with the gulls screaming overhead, and the grey wastes of ocean moaning about the unkindly rocks. And I knew! The taxidermist from Tangier, the longish packing-cases, the square boxes--Ralph Warriner and old man Fournier were running guns and ammunition into Morocco!"

Miranda could not repress an exclamation. She had no doubt that Wilbraham was right; the theory fitted in with Ralph's adventurous character. M. Fournier no doubt made the arrangements, and provided the capital; Ralph worked the cargo across from England to Morocco. And to make it safe for himself to venture upon English soil, he had altered the rig of the Tarifa in some unfrequented port, and somehow arranged the deception concerning his death.

"You think as I thought in Rosevear," said Wilbraham, looking shrewdly into her face. "I only wish you could participate in the delight I felt. I had my fingers on the secret now, and it was such a perfect, profitable secret, for, quite apart from the other affair, gun-running in Morocco is itself an offence against the law. I fairly hugged myself. 'Ambrose,' said I, 'never in all your puff have you struck anything like this. Fouché you shall trample under foot and Sherlock Holmes shall be your washpot; you are the best in the world. The faceless mariner was a fraud, a freak from Barnum's. Here at last is Eldorado, and there's no fly anywhere upon the gilding.' Thus, Mrs. Warriner, I soliloquised, and took the next boat back to Penzance; from Penzance I travelled by train to Plymouth; from Plymouth I sailed in an Orient boat to Gib, and from Gib I crossed to Tangier, where I had a few minutes' conversation with one or two officers of the custom-house.

"Morocco as a social institution has many points of convenience which it is useful for men like Warriner and myself to know. Here's a small case in point. If you wish to smuggle forbidden goods into the country, you hire the custom-house officials to unload your cargo for you at night somewhere on the beach. Thus you avoid much trouble, all chance of detection and you secure skilled workmen. I had no doubt that Warriner had followed this course. So I hired the custom-house officials to tell me the truth, and out it came. The Tarifa had landed its cargo in the bay a mile and a half from Tangier a couple of days before I arrived, and M. Fournier had supervised the unloading, and the captain of the Tarifa was no longer the grizzled sea-dog, Mr. Thomas Discipline, but a gentleman of a slight figure, blue eyes, and fair hair. That middle-aged cherub, in a word, with whom you and I are both familiar, and who now calls himself Mr. Jeremy Bentham. When I had derived this information I walked into M. Fournier's shop and bought a stuffed jackal. There was a tourist making purchases, so I asked my question quietly as I leaned my elbows on the counter.

"'How did you work the situation on Rosevear?' said I, 'and how's my sweet friend, Ralph Warriner?'
