He ate a number of dinners at the same place—more than were good for him, I may add without disparaging their quality; for he fell in love with Miss Margovan, proposed marriage to her and was heartlessly accepted. Several weeks after I had been informed of the engagement, but before it had been convenient for me to make the acquaintance of the young woman and her family, I met one day on Kearney street a handsome but somewhat dissipated-looking man whom something prompted me to follow and watch, which I did without any scruple whatever. He turned up Geary street and followed it until he came to Union square. There he looked at his watch, then entered the square. He loitered about the paths for some time, evidently waiting for someone. Presently he was joined by a fashionably dressed and beautiful young woman and the two walked away up Stockton street, I following. I now felt the necessity of extreme caution, for although the girl was a stranger it seemed to me that she would recognize me at a glance. They made several turns from one street to another and finally, after both had taken a hasty look all about—which I narrowly evaded by stepping into a doorway—they entered a house of which I do not care to state the location. Its location was better than its character. I protest that my action in playing the spy upon these two strangers was without assignable motive. It was one of which I might or might not be ashamed, according to my estimate of the character of the person finding it out. As an essential part of a narrative educed by your question it is related here without hesitancy or shame. A week later John took me to the house of his prospective father-in-law, and in Miss Margovan, as you have already surmised, but to my profound astonishment, I recognized the heroine of that discreditable adventure. A gloriously beautiful heroine of a discreditable adventure I must in justice admit that she was; but that fact has only this importance: her beauty was such a surprise to me that it cast a doubt upon her identity with the young woman I had seen before; how could the marvelous fascination of her face have failed to strike me at that time? But no—there was no possibility of error; the difference was due to costume, light and general surroundings. John and I passed the evening at the house, enduring, with the fortitude of long experience, such delicate enough banter as our likeness naturally suggested. When the young lady and I were left alone for a few minutes I looked her squarely in the face and said with sudden gravity: “You, too, Miss Margovan, have a double: I saw her last Tuesday afternoon in Union square.” She trained her great gray eyes upon me for a moment, but her glance was a trifle less steady than my own and she withdrew it, fixing it on the tip of her shoe. “Was she very like me?” she asked, with an indifference which I thought a little overdone.
