"And as for why they didn't take me with them, one reason is that I wouldn't have gone. Why should I? I should have been in their way, and they most certainly would have been in mine. We parted on the very best of terms; we correspond; one of these days I'm going to pay them a long visit. But, from a purely professional point of view, I've never been able to fill their place, especially his. You've very nearly finished that cigar. Won't you have another?"

"No, thank you; I'm not at the end of this; I'm enjoying it--slowly."

She watched the rings of her cigarette smoke ascending to the ceiling.

"You see, in my profession, there are so very few gentlemen; and of all the professions in the world, it's the one in which gentlemen are most needed, the one in which they're sure to get the best reward for their labours. There are one or two things in my mind, big things, things involving quite possibly thousands of pounds, which I can't work alone, in which I need the co-operation of a man whose birth and breeding, whose knowledge of the manners and customs of good society are beyond question. Now, you're the very sort of person I want; Eton and the Guards; from my point of view there couldn't be a finer qualification."

"How do you come to know anything about me?"

"Your name--Sydney Beaton--was on the tab of that very well-worn coat which you had on when first I met you. I know all about Sydney Beaton; shall I tell you what I do know?"

"You needn't."

"I thought you said that you'd forgotten such a lot; that your mind, beyond a certain point, was a blank?"

She was eyeing him with a malicious twinkle in her laughing eyes; he was grimly silent, meeting her look with what seemed to be a strange defiance.

"I'd rather not remember--now."
