"Perhaps he thinks he can extort a good sum from me by way of ransom?"
"No, it isn't that. Nor is it jealousy, nor spite, nor anything of that kind. I know the motive, I think—but I wish we could get hold of Hahn. I will shut myself up alone and turn it over in my mind for half an hour presently."
"Meanwhile, what I want to know is, apart from all your professional subtleties—which I confess I can't understand—can you get back the cameo?"
"That," said Hewitt, stopping at the corner of the street, "I am rather afraid I can not—nor anybody else. But I am pretty sure I know the thief."
"Then surely that will lead you to the cameo?"
"It may, of course; but, then, it is just possible that by this evening you may not want to have it back, after all."
Lord Stanway stared in amazement.
"Not want to have it back!" he exclaimed. "Why, of course I shall want to have it back. I don't understand you in the least; you talk in conundrums. Who is the thief you speak of?"
"I think, Lord Stanway," Hewitt said, "that perhaps I had better not say until I have quite finished my inquiries, in case of mistakes. The case is quite an extraordinary one, and of quite a different character from what one would at first naturally imagine, and I must be very careful to guard against the possibility of error. I have very little fear of a mistake, however, and I hope I may wait on you in a few hours at Piccadilly with news. I have only to see the policemen."
"Certainly, come whenever you please. But why see the policemen? They have already most positively stated that they saw nothing whatever suspicious in the house or near it."
