feigned devotion which you wrote to me later under seal of strictest secrecy. You went to Cairo, and none knew of our secret--the secret that you intended to make me your wife. And how have you kept your promise? To-day my father has informed me that you are to marry Mary! Imagine the blow to me! My father expects me to rejoice, little dreaming how I have been fooled; how lightly you have treated a woman's affections and aspirations. Some there are who, finding themselves in my position, would place in Mary's hands the packet of your correspondence which is before me as I write, and thus open her eyes to the fact that she is but the dupe of a man devoid of honour. Shall I do so? No. Rest assured that I shall not. If my sister is happy, let her remain so. My vendetta lies not in that direction. The fire of hatred may be stifled, but it can never be quenched.

I remembered them now, and discerned his meaning. He was at least an honest upright man who, although sometimes a trifle eccentric, had my interests deeply at heart. In the progress I had made in my profession I owed much to him, and even in my private affairs he had sought to guide me, although I had, alas! disregarded his repeated warnings.I took up one after another of the letters my friend had examined, and found them to be the correspondence of a woman who was either angling after a wealthy husband, or who loved him with all the strength of her affection. Some of the communications were full of passion, and
