He laughed heartily at what he termed the woman’s audacity; then, after some further discussion of the subject, we dropped it as one of those little mysteries of life that are beyond solution.

On relinquishing my position at the dispensary I wandered heedlessly hither and thither in London. The weather was still hot, more oppressive even than I had felt it at Naples or at Leghorn, and all seemed dull because my friends were away in the country or at the seaside. Through the Lancet I was offered a three months’ engagement as assistant to a doctor in Northumberland, but I declined it, as it was too far from London. Somehow I felt it necessary, for the elucidation of the mystery of the Seahorse, to remain in town—why I cannot tell.

One day in response to a note, I called upon Macfarlane, the specialist in lunacy, and found him seated in his consulting-room, a fine apartment furnished in old oak, of which he was an ardent collector, and surrounded by a number of fine old clocks of various periods.

“Well, Pickering,” he exclaimed cheerily, rising to greet me, “I’ve got some news for you about your—what shall we call him—foundling, eh?”

“That’s a good description,” I laughed. “Captain Seal used to call him ‘Old Mister Mystery.’ But what is the news?”

His brain is clearing, but is not yet rightly balanced. Now and then his ideas run in the direction of a design made up of creepy-looking demons and imps. There’s no doubt about it, that whoever he is, he’s a man of some talent. Did you see what was in the Telegraph the other day?”

“I saw a distorted story about the Seahorse,” I answered.

“But on the following day there was a short statement regarding this nameless patient of ours. They sent a reporter to me to obtain further details, but I did not consider myself justified in giving them. The less the public knows about the affair the better—that’s my opinion.”

“Certainly,” I said. “I’m very glad you did not allow yourself to be interviewed.”

Then I turned myself to the uneven scribble, mostly in pencil, which had been executed by the lunatic. My hopes were quickly dashed, for I found it poor stuff. Sometimes it appeared as though he wished to write a letter, for there were the preliminary words, “Dear sister,” “Dear Harry,” and “My dear sir.” Once he started to write a nautical song, whether of his own composition or not I am unaware. The lines, written quite distinctly, although in a shaky old-fashioned hand, were: —
