The two boats fastened to the little pier that jutted out from the garden lay rocking in its shadow. Here and there lighted windows showed through the thick mist on the margins of the lake. The Enghien Casino opposite blazed with light, though it was late in the season, the end of September. A few stars appeared through the clouds. A light breeze ruffled the surface of the water.

Arsene Lupin left the summer–house where he was smoking a cigar and, bending forward at the end of the pier:

"Growler?" he asked. "Masher?…Are you there?"

A man rose from each of the boats, and one of them answered:

"Yes, governor."

"Get ready. I hear the car coming with Gilbert and Vaucheray."

He crossed the garden, walked round a house in process of construction, the scaffolding of which loomed overhead, and cautiously opened the door on the Avenue de Ceinture. He was not mistaken: a bright light flashed round the bend and a large, open motor–car drew up, whence sprang two men in great–coats, with the collars turned up, and caps.

It was Gilbert and Vaucheray: Gilbert, a young fellow of twenty or twenty–two, with an attractive cast of features and a supple and sinewy frame; Vaucheray, older, shorter, with grizzled hair and a pale, sickly face.

"Well," asked Lupin, "did you see him, the deputy?"

"Yes, governor," said Gilbert, "we saw him take the 7.40 tram for Paris, as we knew he would."

"Then we are free to act?"
