“I’m thinking of going across to Florida very soon to spend the winter at Palm Beach. I was there last year,” remarked Rutherford. “Ever been there, Mr Sandys?”

“Never,” replied Elma’s father. “I must try it one winter. I’ve heard so much about it. Are you in London for long?”

“Only for a week or so on a matter of business. I’m at the Carlton, but I expect very soon to get back to Paris again.”

And so the conversation drifted on, both men well-bred and of charming manner, until the lights were lowered as sign that the restaurant was closing.

The pair saw Mr Sandys and his daughter into their limousine, and then walked together along the Strand.

“Well, how did it work?” asked the man Harrison eagerly.

“Excellent,” declared Gordon Gray, for it was he who had been introduced as Rex Rutherford. “We’ve taken a step in the right direction to-night. It only shows you what can be done by watchfulness. But, oh! the girl! Lovely, isn’t she?”

“Yes, but I hope, my dear Gordon, you’re not going to lose your head to a woman! We’ve other fish to fry with the old man—remember!”

“Lose my head to a woman!” cried Gray, halting beneath the street lamp and looking at him with his dark eyes. “No, my dear fellow, I never do that. It’s the woman who loses her head to me! You told me once that she dances well, didn’t you? Well, the day will come when she will dance to any tune that I choose to play!”
