"You think those letters knocked them off balance? Hell, they loved them. They ate 'em up. It's like those arsenic eaters of yours."
"Poison eaters?"
He nodded. "Poison eaters. They're mixed up. Sick in the head. But trouble doesn't bother them. They live on trouble. They feed on it. Can't do without it. They've got to have a diet that would kill a normal man."
"All of them?"
"All of them."
"Not one knocked off balance?"
"Not one out of six. And just to show you what an amateur I am, each one found something in the letters I hadn't noticed.... Something that proved they couldn't be getting them."
"What?"
"Oh.... Like ... Charlie Hansel found a line that showed the letters are being written to someone who's big. Charlie's a midget, you know that. Plummer noticed something about a loudmouth. And you know how quiet Johnny stammers. He's always whispering the latest from the Kremlin."
"Kay Hill's loud."
