Smeaton came to the point at once. “I am at the present moment considerably interested in the gentleman with whom you left the Savoy yesterday afternoon in a taxi-cab.”

There was just a moment’s pause before she replied. But there were no signs of confusion about her. Her eyes never left his face, and there was no change in her voice when she spoke. She was either perfectly straightforward, or as cool a hand as he had ever met.

“You are interested in Mr Stent? How strange! Gentlemen of your profession do not generally interest themselves in other persons without some strong motive, I presume?”

“The motive is a pretty strong one. At present, other interests require that I do not divulge it,” replied Smeaton gravely. He was pleased with one thing, he had already got the name of the man; he preferred not to confess that he did not know it. And her frank allusion to him as Mr Stent seemed to show that she had nothing to hide. Unless, of course, it was a slip.

“I know I am asking something that you may consider an impertinence,” he went on. “But, if you are at liberty to do so, I should like you to tell me all you know of this gentleman; in short, who and what he is.”

She laughed quite naturally. “But I really fear I can tell you very little. I suppose going away together in a taxi appears to argue a certain amount of intimacy. But in this case it is not so. I know next to nothing of Mr Stent. He is not even a friend, only a man whose acquaintance I made in the most casual manner. And, apart from two occasions about which I will tell you presently, I don’t suppose I have been in his company a dozen times.”

It was a disappointment, certainly, and this time Smeaton did not believe she was speaking the truth. In spite of the silvery laugh and the apparently frank manner. But he must put up with what she chose to give him.

“Do you mind telling me how you first made his acquaintance, Mrs Saxton?”

“Not in the least,” she replied graciously. “Two years ago I was staying in the Hotel Royal at Dinard. Mr Stent was there too. He seemed a very reserved, silent sort of man, and kept himself very much aloof from the others, myself included, although, as I daresay you have guessed, I am of a gregarious and unconventional disposition.”

She gave him a flashing smile, and Smeaton bowed gallantly. “I should say you were immensely popular,” he observed judiciously.
