They followed the winding road for some distance down the mountain, coming at last to a point where a small path branched off.  It was the path leading down the side of the steep overlooking the city, and upon that side no wagon-road could be built.  Seven thousand feet below stretched the sleeping, moon-lit city.  Standing out on the brow of the mountain they seemed to be the only living objects in the world.  There was no sign of life above, below or beside them.

“How long should we be in making the descent?” asked Lorry, a sort of terror possessing him as he looked from the dizzy height into the ghost-like dimness below.

“Three hours, if you are strong.”

“And how are we to get into the castle?  I hadn’t thought of that.”

“There is a secret entrance,” said Quinnox, maliciously enjoying the insistent one’s acknowledgment of weakness.  “If we reach it safely I can take you underground to the old dungeons beneath the castle.  It may be some time before you can enter the halls above, for the secret of that passage is guarded jealously.  There are but five people who know of its existence.”

“Great confidence is placed in you, I see, and worthily, I am sure.  How is it that you are trusted so implicitly?”

“I inherit the confidence.  The captain of the guard is born to his position.  My ancestors held the place before me, and not one betrayed the trust.  The first-born in the last ten generations has been the captain of the guard in the royal palace, possessing all its secrets.  I shall be the first to betray the trust—­and for a man who is nothing to me.”

“I suppose you consider me selfish and vile for placing you in this position,” said Lorry, somewhat contritely.

“No; I have begun the task and I will complete it, come what may,” answered the captain, firmly.  “You are the only being in the world for whom I would sacrifice my honor voluntarily,—­save one.”

“I have wondered why you were never tempted to turn traitor to the Princess and claim the fortune that is represented in the reward.”

“Not for five million gavvos, sir!”

“By George, you are a faithful lot!  Dangloss, Allode and Ogbot and yourself, four honest men to whom she trusts her life, her honor.  You belong to a rare species, and I am proud to know you.”

The stealthy couple found the cave and spent an hour or more within its walls, sallying forth after the tardy darkness had crept down over the mountain and into the peaceful valley.  Then began the tortuous descent.  Quinnox in the lead, they walked, crawled and ran down the narrow path, bruised, scratched and aching by the time they reached the topmost of the summer houses along the face of the mountain.  After this walking was easier, but stealthiness made their progress slow.  Frequently, as they neared the base, they were obliged to dodge behind houses or to drop into the ditches by the roadside in, order to avoid patroling police guards or Axphain sleuth-hounds.  Lorry marveled at the vigil the soldiers were keeping, and was somewhat surprised to learn from the young captain that prevailing opinion located him in or near the city.  For this reason, while other men were scouring Vienna, Paris and even London, hordes of vengeful men searched day and night for a clew in the city of Edelweiss.
