"Does it matter? I desire to make it easier for you."

For a few moments neither spoke. The artificial light in the room had merged once more into daylight. There was again the sound of the opening and shutting of iron doors on deck above them. There were also the harsh tones of orders being given.

Ruxton knew that it was the return of the launch which had conveyed this man's daughter ashore, and that it was being taken on board and stowed within the parent craft. Presently the sounds died away. Once more the light in the saloon became artificial, and the silent throb of engines made themselves felt. The journey had begun.

"My name is Stanislaus. Stanislaus, Prince von Hertzwohl."

Ruxton Farlow did not move a muscle. There was not the quiver of an eyelid, nor one detail of change of expression. Yet he was not unmoved at the mention of the man's real name. Although he had half expected it, it came with something very like a shock.

Stanislaus von Hertzwohl! Did he not know it? Did not the whole wide world know it? Was it not the one name, out of all the great German names associated with the war, which was anathematized more surely even than that of the Kaiser himself?
