"Oh—you're sure of that, are you?"
"Yes. Who I am isn't one of your worries in your new line of business. And you're going to keep still because I can do you a favor—and I will."
"Thanks, Craig. Excuse me—Martin Wall. Sort of a strain keeping track of your names, you know."
"Forget that. I say I can do you a favor—if you'll promise not to mix in my affairs."
"Well—what is it?"
"You're down here looking for a diamond necklace known as Chain Lightning's Collar."
"Great little guesser, you are. Well—what about it?"
"Promise?"
"You deliver the goods, and I'll see."
"All right. You'll find that necklace in Lord Harrowby's pocket right now. And you'll find Lord Harrowby in a room up-stairs."
