"Your words interest me greatly, Mr. Ames. As you know, the grim hard life of the twentieth century palls upon me, and I am deeply interested in everything that pertains to adventure and romance. Tell me more, if you are free to do so, of this slipper which I now return to you." I received Hezekiah's worn little pump into my hands as though it were an object of high consecration, and with a gravity which I hope matched Miss Octavia's own. I was, I think, by this time completely hollisterized, if I may coin the word. "As I am nothing if not frank, Miss Hollister, I will confess to you that this shoe came into my possession in a very curious way. One day last spring I was in Boston, having been called there on professional business. In the evening, I left my hotel for a walk, crossed the Common, took a turn through the Public Garden, where many devoted lovers adorned the benches, and then strolled aimlessly along Beacon Street." "I know that historic thoroughfare well," interrupted Miss Hollister, "as my friend Miss Prudence Biddeford has lived there for half a century, and once, while I was staying in her house, she gave me her recipe for Boston brown bread, thereby placing me greatly in her debt." "Then, being acquainted with the neighborhood and its sublimated social atmosphere, you will be interested in the experience I am about to describe," I continued, reassured by Miss Octavia's sympathetic attention to my recital. "I was passing a house which I have not since been able to identify exactly, though I have several times revisited Boston in the hope of doing so, when suddenly and without any warning whatever this slipper dropped at my feet. All the houses in the neighborhood seemed deserted, with windows and doors tightly boarded, and my closest scrutiny failed to discover any opening from which that slipper might have been flung. The region is so decorous, and acts of violence are so foreign to its dignity and repose, that I could scarce believe that I held that bit of tan leather in my hand. Nor did its unaccountable precipitation into the street seem the act of a housemaid, nor could I believe that a nursery governess had thus sought diversion from the roof above. I hesitated for a moment not knowing how to meet this emergency; then I boldly attacked the bell of the house from which I believed the slipper to have proceeded. I rang until a policeman, whose speech was fragrant of the Irish coasts, bade me desist, informing me that the family had only the previous day left for the shore. The house he assured me was utterly vacant. That, Miss Hollister, is all there is of the story. But ever since I have carried that slipper with me. It was in my pocket to-night as I traversed the upper halls of your house, seeking the ghost of that British soldier, and I had just discovered my loss when I heard you calling. In returning it you have conferred upon me the greatest imaginable favor.
