It was easy enough to re-create for himself, almost as vivid as reality, her beautiful face with the golden hair showing under the edges of the hood, and the startled look of the dark blue eyes when they first met his own.

Relief and joy had been in that look too.

He could read it.
John had learned in Munich the location of Auersperg's principal castle.
It was Zillenstein in a spur of the Eastern Alps just inside Austria, where for centuries the Auerspergs had held great state, as princes of the Holy Roman Empire.

Now when they were princes of both the German and the Austro-Hungarian empires with their greater fealty for the former, they often went there nevertheless, and John's information in Munich made him quite sure that the prince had gone directly toward the ancient stronghold.
Auersperg could cover the distance quickly in his powerful automobiles, but it would take John a long time on foot, helped by an occasional ride in a peasant's cart.

Nevertheless he hung on with patience and pertinacity.
