Sometimes it seems that men--yes, and even women too!--if they believe in a thing strongly enough, they get a strength or endurance that they wouldn't have believe possible.

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.

~ Carter Dickson

Put it in terms of the not-too-serious, if you like. Who got into that locked room? And how was it done? And why should the cup have been moved again? We're up against the essential detective problems of who, how, and why. Simply because there was no murder or near-murder, does that make the mystery one bit less baffling?

~ Carter Dickson

That sounds silly, doesn't it? Running away just because you don't want to hurt somebody's feelings? But did you ever think how much of our lives we spend,dodging and twisting and making things difficult for ourselves, to avoid hurting somebody's feelings. Even people with absolutely no claim on us?
