"Your name?" said the commissary.

"Charles Petit."

"Age?"

"Believed to be twenty-seven, but as no record was kept of my birth I cannot be certain."

"Abode?"

"Changeable. Of late I have dwelt in the Cabaret Noir, Boulevard de Montmartre."

"You are generally known as 'The Worm?'"

"That is so."

"You have served several periods of imprisonment, and have paid over 400 francs in fines?"
