If I would! I think my face must have shown my satisfaction, for Mr. Alvord, who was watching me, sarcastically remarked: "You don't seem to find any difficulties in that communication. Now, what do you think of this one?" He held out another letter which had been directed to him, and which he had opened. Its contents called up a shade of color to my cheek, for I did not want to go through the annoyance of explaining myself again: "DEAR SIR: "From a strange advertisement which has lately appeared in the _Herald_, I gather that information is wanted of a young woman who on the morning of the eighteenth inst. entered my store without any bonnet on her head, and saying she had met with an accident, bought a hat which she immediately put on. She was pale as a girl could be and looked so ill that I asked her if she was well enough to be out alone; but she gave me no reply and left the store as soon as possible. That is all I can tell you about her." With this was enclosed his card: PHINEAS COX, _Millinery_, _Trimmed and Untrimmed Hats_, ---- Sixth Avenue. "Now, what does this mean?" asked Mr. Alvord. "The morning of the eighteenth was the morning when the murder was discovered in which you have shown such interest." "It means," I retorted with some spirit, for simple dignity was thrown away on this man, "that I made a mistake in choosing your office as a medium for my business communications." This was to the point and he said no more, though he eyed the letter in my hand very curiously, and seemed more than tempted to renew the hostilities with which we had opened our interview. Had it not been Saturday, and late in the day at that, I would have visited Mr. Cox's store before I slept, but as it was I felt obliged to wait till Monday. Meanwhile I had before me the still more important interview with Mrs. Desberger. As I had no reason to think that my visiting any number in Ninth Street would arouse suspicion in the police, I rode there quite boldly the next day, and with Lena at my side, entered the house of Mrs. Bertha Desberger. For this trip I had dressed myself plainly, and drawn over my eyes--and the puffs which I still think it becoming in a woman of my age to wear--a dotted veil, thick enough to conceal my features, without robbing me of that aspect of benignity necessary to the success of my mission. Lena wore her usual neat gray dress, and looked the picture of all the virtues. A large brass door-plate, well rubbed, was the first sign vouchsafed us of the respectability of the house we were about to enter; and the parlor, when we were ushered into it, fully carried out the promise thus held forth on the door-step. It was respectable, but in wretched taste as regards colors. I, who have the nicest taste in such matters, looked about me in dismay as I encountered the greens and blues, the crimsons and the purples which everywhere surrounded me.
