“Ah! playing to the gallery! Come, Ganimard, I thought you knew me better. Do I, Arsène Lupin, ever waste my time on such puerilities? Would I have written that letter if I could have robbed the baron without writing to him? I want you to understand that the letter was indispensable; it was the motor that set the whole machine in motion. Now, let us discuss together a scheme for the robbery of the Malaquis castle. Are you willing?”

“Well, let us suppose a castle carefully closed and barricaded like that of the Baron Cahorn. Am I to abandon my scheme and renounce the treasures that I covet, upon the pretext that the castle which holds them is inaccessible?”

“Evidently not.”

“Should I make an assault upon the castle at the head of a band of adventurers as they did in ancient times?”

“That would be foolish.”
