“ You? ”

“Sure thing.”

“Oh, I couldn’t!”

“Why not?”

“I tell you I couldn’t.”

“Again, why not?”

“It would seem so unfair.”

“I don’t see anything unfair about it. I call your bluff, that’s all. I admire you immensely, Miss Tuppence, more than any girl I’ve ever met. You’re so darned plucky. I’d just love to give you a real, rattling good time. Say the word, and we’ll run round right away to some high-class jeweller, and fix up the ring business.”

“I can’t,” gasped Tuppence.
