"Edna, if you are as truthful in all matters as you have proved in your dislikes, I may safely intrust this key to jour keeping. It belongs to that marble temple in my sitting-room, and opens a vault that contains my will and a box of papers, and--some other things that I value. There is no possibility of entering it, except with this key, and no one but myself knows the contents. I wish to leave the key with you, on two conditions: first, that you never mention it to any one--not even my mother, or allow her to suspect that you have it; secondly, that you promise me solemnly you will not open the tomb or temple unless I fail to return at the close of four years. This is the tenth of December--four years from to-day, if I am not here, AND IF YOU HAVE GOOD REASON TO CONSIDER ME DEAD, take this key (which I wish you to wear about your person) to my mother, inform her of this conversation, and then open the vault. Can you resist the temptation to look into it? Think well before you answer." He had disengaged the golden key from his watch-chain and held it in his hand. "I should not like to take charge of it, Mr. Murray. You can certainly trust your own mother sooner than an utter stranger like myself." He frowned and muttered an oath; then exclaimed: "I tell you I do not choose to leave it in any hands but yours. Will you promise or will you not?" The dreary wretchedness, the savage hopelessness of his countenance awed and pained the girl, and after a moment's silence, and a short struggle with her heart, she extended her hand, saying with evident reluctance: "Give me the key, I will not betray your trust." "Do you promise me solemnly that you will never open that vault, except in accordance with my directions? Weigh the promise well before you give it." "Yes, sir; I promise most solemnly." He laid the key in her palm and continued: "My mother loves you--try to make her happy while I am away; and if you succeed, you will be the first person to whom I have ever been indebted. I have left directions concerning my books and the various articles in my rooms. Feel no hesitation in examining any that may interest you, and see that the dust does not ruin them. Good-bye, child; take care of my mother." He held out his hand, she gave him hers for an instant only, and he mounted, lifted his cap, and rode away.
