It was a quarter past eleven and the theatres were disgorging their usual nightly crowds. The most human thoroughfare in any of the world's great cities was at its best and brightest. Everywhere commissionaires were blowing their whistles, the streets were thronged with slowly-moving vehicles, the pavements were stirring with life. The little crowd which had gathered in front of the chemist's shop was swept away. After all, none of them knew exactly what they had been waiting for. There was a rumor that a woman had fainted or had met with an accident. Certainly she had been carried into the shop and into the inner room, the door of which was still closed. A few passers-by had gathered together and stared and waited for a few minutes, but had finally lost interest and melted away. A human thoroughfare, this, indeed, one of the pulses of the great city beating time night and day to the tragedies of life. The chemist's assistant, with impassive features, was serving a couple of casual customers from behind the counter. Only a few yards away, beyond the closed door, the chemist himself and a hastily summoned doctor fought with Death for the body of the girl who lay upon the floor, faint moans coming every now and then from her blue lips.

Tavernake, whose forced inaction during that terrible struggle had become a burden to him, slipped softly from the room as soon as the doctor had whispered that the acute crisis was over, and passed through the shop out into the street, a solemn, dazed figure among the light-hearted crowd. Even in those grim moments, the man's individualism spoke up to him. He was puzzled at his own action, He asked himself a question—not, indeed, with regret, but with something more than curiosity and actual selfprobing—as though, by concentrating his mind upon his recent course of action, he would be able to understand the motives which had influenced him. Why had he chosen to burden himself with the care of this desperate young woman? Supposing she lived, what was to become of her? He had acquired a certain definite responsibility with regard to her future, for whatever the doctor and his assistant might do, it was his own promptitude and presence of mind which had given her the first chance of life. Without a doubt, he had behaved foolishly. Why not vanish into the crowd and have done with it? What was it to him, after all, whether this girl lived or died? He had done his duty—more than his duty. Why not disappear now and let her take her chance? His common sense spoke to him loudly; such thoughts as these beat upon his brain.

Just for once in his life, however, his common sense exercised an altogether subordinate position. He knew very well, even while he listened to these voices, that he was only counting the minutes until he could return. Having absolutely decided that the only reasonable course left for him to pursue was to return home and leave the girl to her fate, he found himself back inside the shop within a quarter of an hour. The chemist had just come out from the inner room, and looked up at his entrance.

“She'll do now,” he announced.

Tavernake nodded. He was amazed at his own sense of relief.

“I am glad,” he declared.

The doctor joined them, his black bag in his hand, prepared for departure. He addressed himself to Tavernake as the responsible person.

“The young lady will be all right now,” he said, “but she may be rather queer for a day or two. Fortunately, she made the usual mistake of people who are ignorant of medicine and its effects—she took enough poison to kill a whole household. You had better take care of her, young man,” he added dryly. “She'll be getting into trouble if she tries this sort of thing again.”

“Will she need any special attention during the next few days?” Tavernake asked. “The circumstances under which I brought her here are a little unusual, and I am not quite sure—”

“Take her home to bed,” the doctor interrupted, “and you'll find she'll sleep it off. She seems to have a splendid constitution, although she has let herself run down. If you need any further advice and your own medical man is not available, I will come and see her if you send for me. Camden, my name is; telephone number 734 Gerrard.”
