Seated at a distance, he watched with increasing interest the changes which passed over his prisoner's handsome countenance. He noted the calmness which now marked the features he had so lately seen writhing in deepest agony, and wondered from what source the strength came which enabled this young man to sit so stoically under the eyes of people from whose regard, an hour before, he had shrunk with such apparent suffering. Was it that courage comes with despair? Or was he too absorbed in his own misery to note the shadow it cast about him? His brooding brow and vacant eye spoke of a mind withdrawn from present surroundings. Into what depths of remorse, who could say? Certainly not this old detective, seasoned though he was by lifelong contact with criminals, some of them of the same social standing and cultured aspect as this young man. At the station in Brooklyn he rejoined his prisoner, who scarcely looked up as he approached. In another hour they were at Police Headquarters and the serious questioning of Mr. Adams had begun. He did not attempt to shirk it. Indeed, he seemed anxious to talk. He had a burden on his mind, and longed to throw it off. But the burden was not of the exact nature anticipated by the police.

Indeed, my recollections are all of very different scenes than this country affords. My mother having died while I was still an infant, I was sent very early in life to the Old World, from which my father had originally come. When I returned, which was not till this very year, I found my father dying, and my brother a grown man with money--a great deal of money--which I had been led to think he was ready to share with me. But after my father was laid away, Felix" (with what effort he uttered that name!) "Felix came to New York, and I was left to wander about without settled hopes or any definite promise of means upon which to base a future or start a career. While wandering, I came upon the town where my father had lived in early youth, and, hunting up his old friends, I met in the house of one who had come over from Scotland with my father a young lady" (how his voice shook, and with what a poignant accent he uttered that beloved name) "in
