"Where is Guerchard ?" M.Formery presented Guerchard to him.
"Are you on their track?
Have you a clue ?" said the millionaire.
"I think," said M.Formery in an impressive tone, "that we may now proceed with the inquiry in the ordinary way." He was a little piqued by the millionaire's so readily turning from him to the detective.

He went to a writing-table, set some sheets of paper before him, and prepared to make notes on the answers to his questions.
The Duke came back into the drawing-room; the inspector was summoned.
M.Gournay-Martin sat down on a couch with his hands on his knees and gazed gloomily at M.Formery.Germaine, who was sitting on a couch near the door, waiting with an air of resignation for her father to cease his lamentations, rose and moved to a chair nearer the writing-table.
Guerchard kept moving restlessly about the room, but noiselessly.

At last he came to a standstill, leaning against the wall behind M.
Formery.
M.Formery went over all the matters about which he had already questioned the Duke.

He questioned the millionaire and his daughter about the Charolais, the theft of the motor-cars, and the attempted theft of the pendant.

He questioned them at less length about the composition of their household--the servants and their characters.
