“The most charming spot on the whole Riviera. By the way,” he added, “one of my old friends is already in Cannes, Colonel Murray-Kerr. Do you happen to know him? He was military attach at Vienna, Rome and Paris until he retired.”

A curious expression passed over her countenance as he mentioned the name. But it vanished instantly, as, glancing up, she looked at him with the frank look that was so characteristic.

“No. I don’t think we have ever met. Murray-Kerr? No. The name is not familiar. He was in the diplomatic service, you say?”

“Yes, for about fifteen years. I had hoped he would have been one of the party here, but he slipped away a week ago, attracted, as usual in winter, by the charms of Cannes.”

“He gambles at Monte Carlo, I suppose?”

“I think not. He’s, nowadays, one of the old fogies of the Junior United Service, and thinks of nothing but the lustre of his patent-leather boots and the chance of shooting with friends. But he’s so well-known in town, I felt sure that you must have met him,” added Dudley meaningly.

“One meets so many people,” she replied carelessly, “and so many are not introduced by name, that it is difficult to recollect. We haven’t the least knowledge of the names of people we’ve known by sight for months. And I’m awfully bad at recollecting names. I always remember faces, but can’t furnish them with names. The position is often extremely awkward and ludicrous.”

The false note in her explanation did not escape his sensitive hearing. Her sudden glances of surprise and annoyance when he had mentioned the colonel’s name had roused suspicion in his mind, and he felt convinced that she was well acquainted with the man who had warned him against her in such mysterious terms.

“If I remember aright,” he said, “the colonel once mentioned you.”

“Mentioned me?” she exclaimed with undisguised surprise, and not without an expression of alarm. In an instant, however, she recovered her self-possession. “Did he say any nice things of me?”
