"I well remember the underground passages, the walled ways, the secret panels, and the like of the ancient place."

Henri nudged his chum, and then briefly narrated how the fortune of the Trouvilles had been saved through the use of these same concealed avenues and by the plan of the same two boys now sitting in this drawing-room.

The old noble listened intently to the story, told without embellishment or boast, and at the point where Henri referred to the delivery of the treasure to his mother the duke clapped his hands in applause.

"Salisky," he called to the special messenger, "I desire to keep these young gentlemen as long as possible. Is there an emergency that commands their return?"

"Your grace," stated Salisky, "it grieves me to say that it is most important that they serve as pilots in our journey back to the front. Even now dispatches are being prepared, and we must be on the wing at sunrise to-morrow."

"Ah, the same duty that holds my son in its grip, the call of country, and which by my infirmity of years I may not answer. Not your country, my boy, but your trust, nevertheless. But this is not your last visit by many, I sincerely hope. A Trouville, a Trouville," he muttered, "without fear."

"Oh, another thought, you have not broken bread with me." The duke struck a bell on the table at his side.

From the dining-room windows the Prospekt could be seen, and Henri saw something besides the Prospekt—several horsemen in parti-colored uniforms pacing their mounts slowly up and down in front of the palace.
