Mysterious Mr. Sabin by E. Phillips Oppenheim

The pitch of conversation had risen higher, still mingled with the intermittent popping of corks and the striking of matches. Blue wreaths of cigarette smoke were curling upwards -- a delicate feeling of "abandon" was making itself felt amongst the roomful of people. The music grew softer as the babel of talk grew in volume. The whole environment became tinged with a faint but genial voluptuousness. Densham was laughing over the foibles of some mutual acquaintance; Wolfenden leaned back in his chair, smoking a cigarette and sipping his Turkish coffee. His eyes scarcely left for a moment the girl who sat only a few yards away from him, trifling with a certain dainty indifference with the little dishes, which one after the other had been placed before her and removed. He had taken pains to withdraw himself from the discussion in which his friends were interested. He wanted to be quite free to watch her. To him she was certainly the most wonderful creature he had ever seen.

In every one of her most trifling actions she seemed possessed of an original and curious grace, even the way she held her silver fork, toyed with her serviette, raised her glass to her lips and set it down again -- all these little things she seemed to him to accomplish with a peculiar and wonderful daintiness. Of conversation between her companion and herself there was evidently very little, nor did she appear to expect it. He was enjoying his supper with the moderation and minute care for trifles which denote the epicure, and he only spoke to her between the courses. She, on the other hand, appeared to be eating scarcely anything. At last, however, the waiter set before her a dish in which she was evidently interested. Wolfenden recognised the pink frilled paper and smiled. She was human enough then to care for ices. She bent over it and shrugged her shoulders -- turning to the waiter who was hovering near, she asked a question. He bowed and removed the plate.
