"Well, catch him by the throat! There are two of us; we couldn't hope for a better moment."
"What! Why, it's impossible!"
"Impossible? Are you afraid? Very well, I'll do it by myself."
"Look here, Chief, you're not serious!"
"Why shouldn't I be serious?"
"Because one can't arrest a man without a reason."
"Without a reason? A scoundrel like this? A murderer? What more do you want?"
"In the absence of compulsion, of catching him in the act, I want something that I haven't got."
"What's that?"
"A warrant. I haven't a warrant."
