She looked astounded, of course, but I would not let her answer me. "Don't speak a word," I cried, "it will only make your toothache worse; and don't look as if some hobgoblin had jumped up on the kitchen table. I guess I know my duty, and just what kind of a breakfast I will have in the morning, if you sit up all night groaning with the toothache." And I was out of the room before she had more than begun to say that it was not so bad, and that I needn't trouble, and all that, which was true enough, no doubt, but not what I wanted to hear at that moment. When Lena came in, I saw by the brightness of her face that she had accomplished her double errand. I therefore signified to her that I was satisfied, and asked if she was too tired to go out again, saying quite peremptorily that Sarah was ill, and that I was going to the drug-store for some medicine, and did not wish to go alone. Lena's round-eyed wonder was amusing; but she is very discreet, as I have said before, and she ventured nothing save a meek, "It's very late, Miss Butterworth," which was an unnecessary remark, as she soon saw. I do not like to obtrude my aristocratic tendencies too much into this narrative, but when I found myself in the streets alone with Lena, I could not help feeling some secret qualms lest my conduct savored of impropriety. But the thought that I was working in the cause of truth and justice came to sustain me, and before I had gone two blocks, I felt as much at home under the midnight skies as if I were walking home from church on a Sunday afternoon. There is a certain drug-store on Third Avenue where I like to deal, and towards this I ostensibly directed my steps. But I took pains to go by the way of Lexington Avenue and Twenty-seventh Street, and upon reaching the block where this mysterious couple were seen, gave all my attention to the possible hiding-places it offered. Lena, who had followed me like my shadow, and who was evidently too dumfounded at my freak to speak, drew up to my side as we were half-way down it and seized me tremblingly by the arm. "Two men are coming," said she. "I am not afraid of men," was my sharp rejoinder. But I told a most abominable lie; for I am afraid of them in such places and under such circumstances, though not under ordinary conditions, and never where the tongue is likely to be the only weapon employed. The couple who were approaching us now seemed to be in a merry mood. But when they saw us keep to our own side of the way, they stopped their chaffing and allowed us to go by, with just a mocking word or two. "Sarah ought to be very much obliged to you," whispered Lena.
