I never met a gal who represented a mystery to me in quite the fetchin' way you did. It'd be dull and dreary just to find out how a crook got in and out of a locked room to steal a gold-and-jewelled cup. But it's very rummy, and fascinates the old man a bit, to wonder why a crook didn't steal a gold-and-jewelled cup he should have stolen.
