One of them, having moved toward the door, Sholmes leaped to the ground and concealed himself in the shadow. The gentleman in the frock coat and the head-waiter left the house. A moment later a light appeared at the windows of the first floor, but the shutters were closed immediately and the upper part of the house was dark as well as the lower.

“Lupin and the woman are on the ground floor; the two confederates live on the upper floor,” said Sholmes.

Sholmes remained there the greater part of the night, fearing that if he went away Arsène Lupin might leave during his absence. At four o’clock, seeing two policemen at the end of the street, he approached them, explained the situation and left them to watch the house. He went to Ganimard’s residence in the rue Pergolese and wakened him.

“I have him yet,” said Sholmes.

“Arsène Lupin?”

“Yes.”

“If you haven’t got any better hold on him than you had a while ago, I might as well go back to bed. But we may as well go to the station-house.”

They went to the police station in the rue Mesnil and from there to the residence of the commissary, Mon. Decointre. Then, accompanied by half a dozen policemen, they went to the rue Chalgrin.

“Anything new?” asked Sholmes, addressing the two policemen.

“Nothing.”
