If only the girls hadn't been there, I'd have trussed the rascals up, waited until they had got their senses back, and then put them through the third degree until I'd found out the name of their employer. But I wouldn't for the world have the girls know what those scoundrels were up to. They'd never have a happy moment. They'd worry themselves to death. We've got to keep this thing absolutely to ourselves."
