"Do you think so?" said Philippe, who seemed relieved by this assertion.

"Certainly! But on one condition, that we establish our right firmly. There has been a violation of the frontier. That is beyond dispute. Let us prove it; and every chance of a conflict is removed."

"But, if we don't succeed in proving it?" asked Philippe.

"Ah, in that case, it can't be helped!... Of course, they will dispute it. But have no fear, my boy: the proofs exist; and we can safely go ahead.... Come along, they're waiting for us downstairs...."

He grasped the door-handle.

"Father!"

"Look here, what's the matter with you to-day? Aren't you coming?"

"No, not yet," said Philippe, who saw a way out and who was making a last effort to escape. "Presently.... I must absolutely tell you.... You and I start from a different point of view.... I have rather different ideas from yours ... and, as the occasion happens to present itself ..."

"Impossible, my boy! They are waiting for us...."

"You must hear me," cried Philippe, blocking the way. "I refuse to accept with a light heart a responsibility that is not in accordance with my present opinions; and that is why an explanation between us has become inevitable."
