"And the police?"

"The police came and went. It was very strange. Nothing further was heard of the matter. But no one about here will go within a mile of the place after nightfall."

"And the servants—what became of them?"

The man shrugged. "They did not come from around here. They were Germans, who came with the Baron. If the police are satisfied, I am."

The man shrugged and drained his glass.

"The other castles are ruined, you say? Then it cannot be long before Szolnok will share their fate—since it is not occupied," suggested Renwick.

"Perhaps," said the man indifferently, rising with a view to closing the conversation.

Renwick ordered another glass of beer, and sat looking out of the small casement window at the passers-by, thinking deeply.

The inspiration of Herr Koulas had at least set him upon a scent which still held him true upon this trail. The information he had received might mean much or little. German servants? Had Goritz used the servants of Baron Neudeck in unraveling the secret of the stolen plans? Had they been implicated in the affair? Did he hold them his creatures by a knowledge of their share in the guilty transaction? Three years had passed since the killing of Neudeck. What had happened in the meanwhile? Had the title of the property passed to others? Had the Schloss been occupied since the Baron's death, or was it deserted? He evolved a theory rapidly, determining to test it at once. It would perhaps be imprudent to question further this innkeeper, a public character, and it seemed quite probable that he knew little more than had already been told. A visit to the farmhouses in the valley would reveal something. He would go——

Renwick had been gazing out of the window, but his attention was suddenly arrested by the figure of a man at the corner of the street, who stood, smoking a cigarette. There was nothing unusual in his clothing or demeanor, but the thing which had startled Renwick into sudden alertness was the rather vague impression that somewhere he had seen this man's face before. A vague impression, but definite in the sense that to Renwick the face had been associated with something unpleasant or disagreeable. But even as Renwick looked, the man tossed his cigarette into the cobbles and turning on his heel walked up the street, passing out of Renwick's range of vision. The Englishman started up from his unfinished glass with the notion of following, but a second thought urged caution. It was still light outside, and if the stranger's memory for faces were better than his own, a meeting face to face would merely court unnecessary danger. So Renwick returned to his bench and made a pretense of finishing his beer, awaiting in safety the darkness. Where had he seen this man before? He searched his mind with painful thoroughness—wondering if the injury to his head had robbed his brain of some of its clearness. He had seen this man's face before—before his sickness—he was sure of that. Hadwiger, Lengelbach, Linder—one by one he recalled the secret service men. The face of the stranger was that of none of these. Someone—a shadowy someone—out of darkness—or dreams. Could the idea have been born of some imaginary resemblance, some fancied recollection? The thing was elusive, and so he gave it up, aware that if his brain had played him no trick, there was here another confirmation of his hope that he was on the true scent. Were the threads converging?
