I at once told my lady visitor that I had no doubt the keys were hers; and that I was ready to hand them over to her. But I ventured to add that it would give me greater security were she to permit my assistant to accompany her to her residence, and there, in his presence, to open the different locks to which the keys belonged. To this proposal not the smallest objection was raised. She begged I would call my assistant, as she had a cab waiting at the door. The direction was given to some place in Bloomsbury, and they drove off. In less than an hour my assistant returned. He stated that the lady opened the street door with the latch-key, and that the other eight keys opened desks, writing-tables, cash-boxes, &c.--all quite correct and satisfactorily. The expense of the advertisement was of course paid. Congratulating myself that this troublesome business was well over, and mentally resolving that another time, under similar circumstances, I should act on my assistant's suggestion, and hand such matters over to the police, I gave orders that all applicants that might come were to be told that the rightful owner had been found and that the keys were disposed of. Two days passed, and I had almost dismissed the whole affair from my mind. On the morning of the third day my attention was attracted by an altercation going on between my servant and an irate lady--well advanced in years--to whom he refused admittance. Anxious to escape disturbance, I gave orders that she should be shewn into my consulting-room, where I presently went to see what she wanted. 'I want to know why you never answered my letter about the bunch of keys you advertised as having found, and which I lost? I have come for them now.' 'But, madam, none of the letters described the keys accurately, and I was therefore not bound to notice any of the written applications that reached me.' 'Not describe them properly! But I _can_ describe them; they were nine in number on the bunch.' 'So far, that is right, madam. Proceed with your description.' The description was entirely wrong; and I told her so. I told her, moreover, that the rightful owner had been found, who had not only described the keys properly, but who had taken my assistant to her house and had used each individual key in his presence. I added that if she were not satisfied, I could furnish her with the address of the lady to whom the keys had been given up, and that she might call and try to establish her claim if she fancied she had one. She was very far from being satisfied. She wanted to argue the matter further and, as I feared, to an unreasonable length. I told her firmly I could waste no further time on her; whereupon she left vowing vengeance.
