"She would make a good enemy," she said. "Who is the vulgar woman who is having supper with that handsome man with the red beard?"

"Oh, that is Lady Beachmore!" Lopez explained. "Beachmore is a man of a good family, he has a good name, and his career as a soldier was an honourable one. There are phases of human nature that beat me entirely, Cara. A case like that makes me feel how little I know. Lady Beachmore was on the variety stage, with nothing piquant about her but her vulgarity. She is plain, she is horribly made up, and yet Beachmore married her."

"Is he a rich man?"

"As things go, yes. He is one of the peers who has enough for his wants and a little to spare, as the old song has it. Why did he marry her, Cara?"

Cara admitted that the problem was beyond her. Lady Beachmore was vulgar enough, in all conscience; she talked loudly and she drank a great deal of champagne. She was extravagantly dressed, but she wore no ornaments—which was unusual in a woman of her class.

"She ought to be smothered in stones," Cara said.

"Bridge," Lopez explained sententiously. "Lady Beachmore is one of the most reckless gamblers in society. Probably that is why she is tolerated in good houses. Everybody knows what a gambler she is except her husband. If I were to hazard a guess I should say that the Beachmore jewels are all in the possession of Aaron Benstein."

Cara nodded. The salon was gradually getting empty. Lord Beachmore said something to his wife, who shook her head, and then he sauntered slowly from the room. Lady Beachmore looked across to the seat where Mrs. Benstein was reclining, and her coarse face grew red with anger. By some kind of magnetic influence the eyes of the two women met, and the former rose. She crossed over to Mrs. Benstein's table, a few low words followed before Mrs. Benstein rose also.

Her eyes were flashing and her breast was heaving. She made a motion towards the jewels in her hair, and then seemed to change her mind. A few of the low, angry words reached Lopez's ears. A sardonic smile was on his lips.

"A curious coincidence," he muttered. "She is actually wearing Lady Beachmore's diamonds! Well, the information should prove valuable. I'll go and see Frobisher to-morrow. The mere hint of what can be done should be worth five hundred pounds."
