“You ought to know better than I, sir. I take it that she was obeying your orders about how to work the trick on me, though it isn’t clear in my mind as yet; but I’m not a detective.”

“Did she promise to marry you as soon as the Flagg drive was down?” Still Mern was boldly taking advantage of the young man’s docility.

“That’s true. I must admit it because it was said in public.”

Mern scratched his ear. The thing was clearing somewhat in Crowley’s direction; the blunderer had not lied on one point at least—the point that Mern found most blindly puzzling. What in the mischief had happened to the nature of Lida Kennard, as Mern knew that nature, so he thought!

“You remember Operative Crowley, do you?”

“Naturally.”

“Are you holding an especial grudge against him?”

“I don’t know why I should, sir. It’s a dirty business he’s in, but he gave me that letter which I turned over to you yesterday, and for some reason he exposed the trick that was being put upon me by the girl. If I can get at the bottom of the thing, for my own peace of mind, I’ll be glad.”

Chief Mern sympathized with that sentiment!

Then he took a little time for reflection. Perhaps a meeting between Latisan and Crowley might strike a few sparks to illuminate a situation that was very much in the dark.
