Philippe looked full at Cagliostro. “I still say, sir, that you lie.”

Cagliostro shrugged his shoulders, as though he were talking to a madman.

“Do you not hear me, sir?” said Philippe.

“Every word.”

“And do you not know what giving the lie deserves?”

“Yes, sir; there is a French proverb which says it merits a box on the ears.”

“Well, sir, I am astonished that your hand has not been already raised to give it, as you are a French gentleman, and know the proverb.”

“Although a French gentleman, I am a man, and love my brother.”

“Then you refuse me satisfaction?”

“I only pay what I owe.”
