CHAPTER XV.
THE EXAMINATION OF SONIA M.Formery gasped: "The real track ?" he muttered.
"Let me show you," said Guerchard.

And he led him to the fireplace, and showed him the opening between the two houses.
"I must go into this myself!" cried M.Formery in wild excitement.
Without more ado he began to mount the steps.

Guerchard followed him.
The Duke saw their heels disappear up the steps.

Then he came out of the drawing-room and inquired for M.Gournay-Martin.

He was told that the millionaire was up in his bedroom; and he went upstairs, and knocked at the door of it.
M.Gournay-Martin bade him enter in a very faint voice, and the Duke found him lying on the bed.
