I had obtained no light from Alexis, and I sought in vain for an explanation of my patient's condition. Of course, it was plausible enough to argue that his passion for Rosa was at the root of the evil; but I remembered Rosa's words to me in the carriage, and I was disposed to agree with them. To me, as to her, it seemed that, though Alresca was the sort of man to love deeply, he was not the sort of man to allow an attachment, however profound or unfortunate, to make a wreck of his existence. No. If Alresca was dying, he was not dying of love.

As Alexis had remarked, it was a lovely summer night, and after quitting the Devonshire I stood idly on the pavement, and gazed about me in simple enjoyment of the scene.

The finest trees in Hyde Park towered darkly in front of me, and above them was spread the star-strewn sky, with a gibbous moon just showing over the housetops to the left. I could not see a soul, but faintly from the distance came the tramp of a policeman on his beat. The hour, to my busy fancy, seemed full of fate. But it was favorable to meditation, and I thought, and thought, and thought. Was I at the beginning of an adventure, or would the business, so strangely initiated, resolve itself into something prosaic and mediocre? I had a suspicion—indeed, I had a hope—that adventures were in store for me. Perhaps peril also. For the sinister impression originally made upon me by that ridiculous crystal-gazing scene into which I had been entrapped by Emmeline had returned, and do what I would I could not dismiss it.

My cousin's wife was sincere, with all her vulgarity and inborn snobbishness. And that being assumed, how did I stand with regard to Rosetta Rosa? Was the thing a coincidence, or had I indeed crossed her path pursuant to some strange decree of Fate—a decree which Emmeline had divined or guessed or presaged? There was a certain weirdness about Emmeline that was rather puzzling.

I had seen Rosa but twice, and her image, to use the old phrase, was stamped on my heart. True! Yet the heart of any young man who had talked with Rosa twice would in all probability have been similarly affected. Rosa was not the ordinary pretty and clever girl. She was such a creature as grows in this world not often in a century. She was an angel out of Paradise—an angel who might pass across Europe and leave behind her a trail of broken hearts to mark the transit. And if angels could sing as she did, then no wonder that the heavenly choirs were happy in nothing but song. (You are to remember that it was three o'clock in the morning.) No, the fact that I was already half in love with Rosa proved nothing.

On the other hand, might not the manner in which she and Alresca had sought me out be held to prove something? Why should such exalted personages think twice about a mere student of medicine who had had the good fortune once to make himself useful at a critical juncture? Surely, I could argue that here was the hand of Fate.

Rubbish! I was an ass to stand there at that unearthly hour, robbing myself of sleep in order to pursue such trains of thought. Besides, supposing that Rosa and myself were, in fact, drawn together by chance or fate, or whatever you like to call it, had not disaster been prophesied in that event? It would be best to leave the future alone. My aim should be to cure Alresca, and then go soberly to Totnes and join my brother in practice.

I turned down Oxford Street, whose perspective of gas-lamps stretched east and west to distances apparent infinite, and as I did so I suddenly knew that some one was standing by the railings opposite, under the shadow of the great trees. I had been so sure that I was alone that this discovery startled me a little, and I began to whistle tunelessly.

I could make out no details of the figure, except that it was a man who stood there, and to satisfy my curiosity I went across to inspect him. To my astonishment he was very well, though very quietly, dressed, and had the appearance of being a gentleman of the highest distinction. His face was clean-shaven, and I noticed the fine, firm chin, and the clear, unblinking eyes. He stood quite still, and as I approached looked me full in the face. It was a terrible gaze, and I do not mind confessing that, secretly, I quailed under it; there was malice and a dangerous hate in that gaze. Nevertheless I was young, careless, and enterprising.
