"The question is, Archie," I said gravely, looking at him with sharp doubt in my eyes, "can I trust you? I suspect you've already set something going, you know."

He had coloured a little. A mere honourable understanding was never in the least binding on him, and I was never quite sure to what extent the exaction of a definite promise would be so.

"Oh, dash it all, Jeff!" he had scoffed rather awkwardly, "anybody'd think you were ashamed of it! All I said was quite harmless—really——"

"I know," I had commented, "meaning no harm. Nine-tenths of the harm in the world's done that way. I don't know that I don't prefer the man who means harm; at least he knows what he's doing.... But why are you so curious about it all?"

His curiosity, I knew, was nothing more or less than a slack indulgence of his desire to hear a secret. He had too Miss Levey's racial gift of turning these things to account. But he had put it rather differently.

"Oh, just friendly interest," he had replied, slapping his jacket pocket. "Where did I put my cigarette case?... We are friends, aren't we?"

"Rather less so when you go chattering about me."

"Sorry, old man," he had replied contritely, though his contrition had been less for his blabbing than that I apparently had taken it amiss. "I didn't think—you didn't tell me not—it slipped out——"

"Well, well—no great harm's done. But if I were you—" if I had hesitated it was merely for a private and subtle relish "—I'd take a memory powder, to use an expression of Miss Windus's."

(You will remember how I had come to overhear that expression, and you may see, by turning back, the precise context of the allusion.)
