"I know the name of Benstein," Hamid said. "He is the old man whom the Shan has had so many dealings with lately. I shouldn't wonder——"

It was the turn of Hamid to break off suddenly, and Lopez smiled. Under the big portico of the Belgrave, the curiously-assorted couple parted. Lopez lingered a moment to finish his cigarette. In an ordinary way he watched the well-dressed crowd flutter up the steps.

"By no means a bad night's work," he muttered. "I've picked up a piece of priceless information, at least I hope so. Unless I am greatly mistaken my dear little Cara is going to ruffle it with the best of them at Pau yet."

CHAPTER IX.

A WORD TO THE WISE.

A soldier of fortune like Lopez was not easily elated by the smiles of the first goddess, but he felt on very good terms with himself as he stood there finishing his cigarette. Most of the people who passed him up the flight of marble steps were familiar to him, and Lopez amused himself by marking them off one by one. He was in an indolent mood now, but his glance grew brighter as a smartly-appointed motor-car drove up and a lady alighted.

She had no covering to her marvellous dead-black hair, though her dress was hidden by a long wrap. She was quite alone, her air was absolutely self-possessed as she looked around her. As she came up the steps she became conscious of Lopez's presence.

She smiled in a slow, languid way, and half held out her hand. "One always meets you in unexpected places," she said. "The last time we came together the conditions were very different to these."

"That is quite true, Isa," Lopez said gravely.

"Mrs. Benstein, if you please," the woman said, with not the faintest trace of annoyance in her tones. The smile was almost caressing. "We had better observe the proprieties. Do you remember the last time we met, Paul Lopez?"
