"Um. Dangerous letters?"
"Filthy dangerous."
"That means trouble if you stay on?"
"Probably."
"What kind?"
"I don't know. It's an audience show. Suppose we let a lunatic in one Sunday night. You draw the pictures. Anything could happen."
"Police?"
"I'm afraid to go to the police."
"Why?"
"That turns it from a private stink into an official stink. That's why Blinky and I've been keeping it quiet. If the story gets out we'll be cancelled."
