M. Verduret drew back quickly.

“Come away,” he whispered to Prosper, “the cur will do as he says; and, alarm once given, farewell to our projects. We must find some other entrance than by this gate.”

They then went along the wall surrounding the garden, in search of a place where it was possible to climb up.

This was difficult to discover, the wall being twelve feet high, and the night very dark. Fortunately, M. Verduret was very agile; and, having decided upon the spot to be scaled, he drew back a few feet, and making a sudden spring, seized one of the projecting stones above him, and, drawing himself up by aid of his hands and feet, soon found himself on top of the wall.

It was now Prosper’s turn to climb up; but, though much younger than his companion, he had not his agility and strength, and would never have succeeded if M. Verduret had not pulled him up, and then helped him down on the other side.

Once in the garden, M. Verduret looked about him to study the situation.

The house occupied by M. de Lagors was built in the middle of an immense garden. It was narrow, two stories high, and with garrets.

Only one window, in the second story, was lighted.

“As you have often been here,” said M. Verduret, “you must know all about the arrangement of the house: what room is that where we see the light?”

“That is Raoul’s bed-chamber.”
