This was on a Friday. There was a matinee the next day, and he attended that, though he had secured a seat for the usual evening entertainment. Then it became a habit of Van Twiller's to drop into the theatre for half an hour or so every night, to assist at the interlude, in which she appeared. He cared only for her part of the programme, and timed his visits accordingly. It was a surprise to himself when he reflected, one morning, that he had not missed a single performance of Mademoiselle Olympe for nearly two weeks. "This will never do," said Van Twiller. "Olympe"--he called her Olympe, as if she were an old acquaintance, and so she might have been considered by that time--"is a wonderful creature; but this will never do. Van, my boy, you must reform this altogether." But half-past nine that night saw him in his accustomed orchestra chair, and so on for another week. A habit leads a man so gently in the beginning that he does not perceive he is led--with what silken threads and down what pleasant avenues it leads him! By and by the soft silk threads become iron chains, and the pleasant avenues Avernus! Quite a new element had lately entered into Van Twiller's enjoyment of Mademoiselle Olympe's ingenious feats--a vaguely born apprehension that she might slip from that swinging bar; that one of the thin cords supporting it might snap, and let her go headlong from the dizzy height. Now and then, for a terrible instant, he would imagine her lying a glittering, palpitating heap at the foot-lights, with no color in her lips! Sometimes it seemed as if the girl were tempting this kind of fate. It was a hard, bitter life, and nothing but poverty and sordid misery at home could have driven her to it. What if she should end it all some night, by just unclasping that little hand? It looked so small and white from where Van Twiller sat! This frightful idea fascinated while it chilled him, and helped to make it nearly impossible for him to keep away from the theatre. In the beginning his attendance had not interfered with his social duties or pleasures; but now he came to find it distasteful after dinner to do anything but read, or walk the streets aimlessly, until it was time to go to the play. When that was over, he was in no mood to go anywhere but to his rooms. So he dropped away by insensible degrees from his habitual haunts, was missed, and began to be talked about at the club. Catching some intimation of this, he ventured no more in the orchestra stalls, but shrouded himself behind the draperies of the private box in which Delaney and I thought we saw him on one occasion.
