“And what do you think about Trilby Andrews?”

“I never heard of her. Who is she?”

That’s all I’ve been doing. I’ve thrown accusations all over the place, and been sure I’d strike a spark somewhere. You rush around and jump to conclusions and have kittens over every flash, and get gorgeously master-minded and confused... But in the end I’ve started to think.”
