"Yes."
"Why, for goodness sake?"
"Because they will discover all the resistance they will care to meet after they have entered."
"Oh! You mean to fix yourself to fight them, then, eh?"
"I don't really think we will have to do any fighting at all, senator."
"I suppose you have prepared another puzzle for me to solve, eh?"
