"My son, I never confide in a man of whom I am ignorant. My friends may rest assured that I treasure some knowledge of them, some episode, perhaps, which they have forgotten, but which in an emergency will compel them to remain my friends." And while he laid one hand on his companion's arm, he touched his own forehead significantly with the other. "Come with me into another room. My servant shall set before you wine of such a vintage that you shall forget your bruises. And do not leave, Monsieur Mercier, until you are rested. Indeed, if I find you asleep in your chair when I return, I will not quarrel with you."

As he followed the priest, Mercier's estimate of his companion possibly took a wider scope than it had done before, and he wondered which of the many episodes in his life which he was unlikely to talk of the priest knew most about.

It was conclusive proof of Father Bertrand's power with the late Duke and Count Felix that he was admitted to the castle without question at so late an hour; and that the soldiers bowed to his authority was apparent when his suggestion that he should see the spy before he saw the Count met with no opposition.

"Lodged in the South Tower?" he said as he followed the jailer.

"Ay, father; it's the safest cage we have."

"Too safe for an innocent bird, master jailer."

"Well, I know naught of his innocence," said the jailer as he thrust the great key into the lock, "but I'm not regretting that he should cheat death. There's no fear about him, and there's none too many brave men in the world that we should want to hurry them out of it."

The jailer had a torch, and he preceded the priest down the narrow passage in the thickness of the walls.

"Asleep, prisoner?" he called out. "Here's a reverend father to see you, and he comes as a friend."
