Fantômas was about to leave the house. He was already stepping onto the terrace when, suppressing an oath, he wheeled about suddenly.

As Juve and Fandor were about to enter the grounds, Detective Michel rose up out of the dusk.

"That you, sir?"

"Well," replied Juve, "is the bird in the nest?"

"Yes, sir, and the cage is well guarded, I assure you. Fifteen of my men kept a strict guard round the house."

"Good. Here is the plan of action. You, Sergeant, will enter the house with Inspector Michel, at my back. The men will continue to watch the exit."

Juve broke off sharply. He saw the door of the house open a little way and Fantômas appear, then vanish again inside the house.

"At last!" cried Juve, who sprang forward, followed by Fandor.

"Slowly, gentlemen! We have now victory in sight, we mustn't imperil it by rashness. You remain on the ground floor. Each one in a room, and don't stir without good reason. I am going up."

"I am going with you," exclaimed Fandor.
