"It's immense. Through Steinweg, we learn the truth about Pierre Leduc. Through Steinweg, we get to know what the famous Kesselbach plan is all about."

Sernine burst out laughing:

"And you need me for that?"

"I don't understand."

"Come, old chap, your offer is childish. You have Steinweg in your hands. If you wish for my collaboration, it is because you have not succeeded in making him speak. But for that fact, you would do without my services."

"Well, what of it?"

"I refuse."

The two men stood up to each other once more, violent and implacable.

"I refuse," said Sernine. "Lupin requires nobody, in order to act. I am one of those who walk alone. If you were my equal, as you pretend, the idea of a partnership would never have entered your head. The man who has the stature of a leader commands. Union implies obedience. I do not obey."

"You refuse? You refuse?" repeated Altenheim, turning pale under the insult.
