"That's what I want," he said, without a moment's reflection.

And, giving the stone a mighty kick, he sent the heap shooting into the road with a roar like an avalanche.

Paul jumped down among the stones, lay flat on his chest and began to scream for help, as though he had met with an accident.

From where he lay, it was impossible, owing to the winding of the road, to hear him in the barracks; but the least cry was bound to carry as far as the shed at the mouth of the tunnel, which was only a hundred yards away at most. The soldiers on guard came running along at once.

He counted only five of them. In an almost unintelligible voice, he gave incoherent, gasping replies to the corporal's questions and conveyed the impression that he had been sent by Prince Conrad to bring back the Comtesse Hermine.

Paul was quite aware that his stratagem had no chance of succeeding beyond a very brief space of time; but every minute gained was of inestimable value, because Bernard would make use of it on his side to take action against the sixth man, the sentry outside the tunnel, and to make his escape with Prince Conrad. Perhaps that man would come as well. Or else perhaps Bernard would get rid of him without using his revolver and therefore without attracting attention.

And Paul, gradually raising his voice, was spluttering out vague explanations, which only irritated without enlightening the corporal, when a shot rang out, followed by two others.

For the moment the corporal hesitated, not knowing for certain where the sound came from. The men stood away from Paul and listened. Thereupon he passed through them and walked straight on, without their realizing, in the darkness, that it was he who was moving away. Then, at the first turn, he started running and reached the shed in a few strides.

Twenty yards in front of him, at the mouth of the tunnel, he saw Bernard struggling with Prince Conrad, who was trying to escape. Near them, the sentry was dragging himself along the ground and moaning.

Paul saw clearly what he had to do. To lend Bernard a hand and with him attempt to run the risk of flight would have been madness, because their enemies would inevitably have caught them up and in any case Prince Conrad would have been set free. No, the essential thing was to stop the rush of the five other men, whose shadows were already appearing at the bend in the road, and thus to enable Bernard to get away with the prince.
