As Hubert pronounced these last words, Gertrude rapped at the door and called in a quaking voice:

"Open, open! The commissioner of the Section, in his scarf of office, is here with the mounted police. He is coming upstairs."

Hubert drew from his coat pockets a brace of double-barreled pistols, cocked them, and said in a low voice:

"I shall sell my life dear; but, by the thousand gods! my first bullet will be for you, my coward and traitor brother-in-law!"

Advocate Desmarais leaped to the door and drew back the bolt. His wife, struck with a sudden inspiration, and displaying, in the terror which seized her, an unwonted strength, dragged her brother into her bed-chamber, which opened on the parlor, slammed the door after her, and shot the bolt into its socket.

Contrary to his expectations, he did not find the officer in the ante-room, and was compelled to go as far as the stair-landing, where he encountered him and accompanied him back to the parlor.

The commissioner was a man of cold and rigid physiognomy; in his suite were some gendarmes of the Republic, and several police agents. Bowing to the commissioner, the advocate said:

"Citizen, if I had a son a traitor to the nation, I would myself give him up to the public powers. I would follow the example of Brutus the Roman." Then stopping short and casting about him looks of stupefaction, he added: "But where has my brother-in-law gone to?"

"That is for me to ask you, Citizen Representative of the people," rejoined the commissioner. "This disappearance is strange!"
