Seal suggested that she might have been aground on the coast of Western Morocco, a country but little known to the civilized world although so near one of the greatest trade routes, and that she might have drifted from the Atlantic to the spot where we had discovered her.

This theory seemed the most likely one, although the presence of the Mysterious Man was utterly unaccountable.

The main point which puzzled Seal, I think, was what he should do with the gold. He regarded the poor old fellow as a gibbering idiot, and had but little to do with him. Customs officers and lunatics were the bluff old seaman’s pet abominations. He would probably have liked to claim the hoard of gold himself if it were not for the existence of one with a prior claim to it, and once or twice he expressed to me an anxiety as to what his owners would say to it all. They were skinflints of the worst type, and would, I expected, probably lay claim to it themselves.

Steaming slowly we passed the Gib. and made a straight course for Cape St. Vincent, which we sighted at dawn one rainy morning, then hugging the Portuguese coast we safely passed the mouth of the Tagus, being hailed more than once by other craft, the skippers all asking us with humorous banter what we had in tow.

Fortunately the weather had improved greatly, and even as we traversed the Bay of Biscay we had no reason to complain, for the old Seahorse rode proudly in our wake, rocking a good deal on account of its house-like shape, but nevertheless giving Seal the greatest satisfaction.

“It’ll make ’em open their eyes, doctor, when we tow ’er up the Thames,” he often said, as he paced his bridge and looked at her straining on the hawser.

Never a day passed but I occupied myself diligently with the documents and manuscripts that had fallen into my hands, but I am fain to confess that beyond what I have already explained to the reader I discovered absolutely nothing. Although I had passed my final examination and could write M.D. after my name, my book-learning was not sufficiently deep that I could decipher and understand those crabbed old screeds.

I showed them to the Mysterious Man, hoping that they would attract his attention and give me some clue to their meaning, but he remained quite passive when he saw them, and turning upon his heel looked out through the round port-hole.

I certainly was very anxious to get back to London to obtain some opinion upon the big vellum book in which Bartholomew da Schorno declared there was a secret that would be discovered hereafter. My voyage, besides being a pleasant one, had been full of excitement, for we had found an object the like of which no living eye had seen, together with an individual who was a complete and profound mystery.

The weather was all that could be desired when we entered the Channel, keeping close in to the coast of Normandy as far as Dieppe, and then taking a direct course across to Beachy Head, where we were signalled as homeward bound. When, however, we were off Folkestone, about nine o’clock one night, a squall struck us so suddenly that even Job Seal was unprepared for it. The glass had fallen rapidly, he had noticed, but such a heavy squall as it proved to be was not to be expected at that season of the year. Within a quarter of an hour a terrific sea was running, and the Thrush seemed ever and anon thrown almost on her beam-ends. I noticed that Seal’s face for the first time during our trip betrayed some anxiety, and not without cause, for he suddenly exclaimed: —
