He paused a while, his head sunk upon his hand, and then continued-"My marriage had diverted me from a project which I cannot enter into now. I have no time, Holly--I have no time! One day, if you accept my trust, you will learn all about it. After my wife's death I turned my mind to it again. But first it was necessary, or, at least, I conceived that it was necessary, that I should attain to a perfect knowledge of Eastern dialects, especially Arabic. It was to facilitate my studies that I came here. Very soon, however, my disease developed itself, and now there is an end of me." And as though to emphasise his words he burst into another terrible fit of coughing.
I gave him some more whisky, and after resting he went on-"I have never seen my boy, Leo, since he was a tiny baby. I never could bear to see him, but they tell me that he is a quick and handsome child. In this envelope," and he produced a letter from his pocket addressed to myself, "I have jotted down the course I wish followed in the boy's education. It is a somewhat peculiar one. At any rate, I could not entrust it to a stranger. Once more, will you undertake it?"
"I must first know what I am to undertake," I answered.
"You are to undertake to have the boy, Leo, to live with you till he is twenty-five years of age--not to send him to school, remember. On his twenty-fifth birthday your guardianship will end, and you will then, with the keys that I give you now" (and he placed them on the table) "open the iron box, and let him see and read the contents, and say whether or no he is willing to undertake the quest. There is no obligation on him to do so. Now, as regards terms. My present income is two thousand two hundred a year. Half of that income I have secured to you by will for life, contingently on your undertaking the guardianship--that is, one thousand a year remuneration to yourself, for you will have to give up your life to it, and one hundred a year to pay for the board of the boy. The rest is to accumulate till Leo is twenty-five, so that there may be a sum in hand should he wish to undertake the quest of which I spoke."
"And suppose I were to die?" I asked.
"Then the boy must become a ward of Chancery and take his chance. Only be careful that the iron chest is passed on to him by your will. Listen, Holly, don't refuse me. Believe me, this is to your advantage. You are not fit to mix with the world--it would only embitter you. In a few weeks you will become a Fellow of your College, and the income that you will derive from that combined with what I have left you will enable you to live a life of learned leisure, alternated with the sport of which you are so fond, such as will exactly suit you."
