But when at length sleep came to him he was not thinking of any weird cavern in the cliff, haunted by mermaid or siren, but of the young witch with her red-gold hair and wonderful eyes who had cast a spell over him, the potency of which was already beginning to make itself felt.

In the course of the forenoon the wind went down, but there was a heavy sea running for hours to come.

Breakfast and dinner came in due course, but with the latter meal a letter was handed to Burgo, the address of which--simply his own name--he at once recognised as being in the calligraphy of Miss Roylance. He opened it with a sinking of the heart. Had she written to say that something had intervened, and that she would not be able to visit him as promised? He motioned to Mrs. Sprowle to remain till he had read it. There might be something in it which would necessitate an answer.

"I was about to explain to you yesterday, when interrupted," it began abruptly, "the reasons by which I was actuated in seeking an interview in the way I did, with one who was a complete stranger to me. To you, I have no doubt, it seemed a bold and unmaidenly thing to do, and only under very special circumstances could such a step be at all excusable. That the circumstances in this case are of a very special kind you will, I trust, be ready to admit by the time you have read to the end of what is here written.

"For various reasons I have deemed it best to put my explanation in writing, the chief one being that at present I am far from sure I shall be able to see you again this evening; indeed, it is by no means unlikely that I may be unable to do so at all. You will understand why when you have read further.

"I must ask you to bear with me while I jot down, as briefly as may be, a few details of my early history which are needful for the due understanding of what follows. I will try not to weary you over-much.

"I was born in India, where my father was in the Civil Service, and was sent to Lausanne at an early age to be educated. My mother died when I was too young to remember her, and I lost my father when I was about twelve years old. Of the two guardians appointed by my father, one is a London solicitor whom I have never seen, the other being Colonel Innes, my mother's brother. To finish this part of my explanation, I may add that when I am twenty-one I shall come into a fortune of ten thousand pounds, and that I am debarred from marrying before that age (I am now just turned twenty) without the consent of my guardians--or rather, of the one who is still living, for my uncle, Colonel Innes, died a year and a half ago.

"When my uncle Innes retired from the army he came to Europe, and, after spending some months in England, he settled down for the winter at Nice. It was there I joined him on leaving school, for his home, he said, was henceforth to be my home; and it was there he met La Signora Offredi, whom he shortly afterwards married, and who is now known to the world as the wife of Sir Everard Clinton.

"The courtship was a very brief one, for my uncle was simply infatuated. His marriage was to make no difference to me; my home was to be still with him--an arrangement which his wife most cordially seconded. Indeed, from the hour I was introduced to her, Lady Clinton--to give her the title by which she is now known--accorded me an amount of affection which my more frigid temperament made it impossible for me to reciprocate in anything like an equivalent degree. On two occasions she took me with her on her visits to her son, a boy of twelve, who was at school also at Lausanne.

"When my uncle had been married about eighteen months a great misfortune befell him. He lost nearly the whole of his fortune by a bank failure. No doubt it preyed deeply on his mind, and a few weeks after the news came he broke down completely. He never rallied, but lingered on for three months, growing gradually weaker, and then died, his wife having scarcely left his side during the whole of his illness. On his deathbed he exacted from me a promise to remain with her, and to be guided by her in everything, in any case till I should come of age. I gave the promise without a thought of any possible consequences which it might entail.
