“If that bull-headed butcher would have joined me, I would have liberated him as I am about to liberate you,” pursued Herne. “But to return to the matter in hand. You recollect the secret passage we then tracked? There is just such another staircase in this tower.”

And stepping to the farther side of the chamber, he touched a small knob in the wall, and a stone flew hack, disclosing an aperture just large enough to allow a man to pass through it.

“There is your road to freedom,” he said, pointing to the hole. “Creep along that narrow passage, and it will bring you to a small loophole in the wall, not many feet from the ground. The loophole is guarded by a bar of iron, but it is moved by a spring in the upper part of the stone in which it appears to be mortised. This impediment removed, you will easily force your way through the loophole. Drop cautiously, for fear of the sentinels on the walls; then make your way to the forest, and if you 'scape the arquebusiers who are scouring it, conceal yourself in the sandstone cave below the beech-tree.”

“And what of you?” asked Fenwoif.

“I have more to do here,” replied Herne impatiently-“away!”

Thus dismissed, Fenwolf entered the aperture, which was instantly closed after him by Herne. Carefully following the instructions of his leader, the keeper passed through the loophole, let himself drop softly down, and keeping close to the walls of the tower till he heard the sentinels move off, darted swiftly across the street and made good his escape.

Meanwhile Herne drew the cowl over his head, and stepping to the door, knocked loudly against it.

“What would you, father?” cried the guard from without.

“Enter, my son, and you shall know,” replied Herne.

The next moment the door was unlocked, and the guard advanced into the dungeon.
