“You told it with a certain amount of hesitation,” he said. “You suggested you might be mistaken in thinking there was anything in it. Now I’m going to make a suggestion with even more hesitation, for it’s ten times wilder than yours, and there is simply nothing to back it up. But here goes all the same.”

“Here you have a trade with something fishy about it. Perhaps you think that’s putting it too strongly; if so, let us say there is something peculiar about it; something, at all events, to call one’s attention to it, as being in some way out of the common. And when we do think about it, what’s the first thing we discover?”

“Not at the moment. But I don’t see what that has to do with it.”

“Quite possibly nothing, and yet it’s an interesting point.”

“Don’t see it.”
