At the Ritz, in Budapest, and also in the train, he had noticed on several occasions a curious exchange of glances between uncle and niece—or was it only his fancy?

Was anything amiss? He lay listening to the owls hooting in the great forest which surrounded the castle on three sides, and reflected deeply. Françoise, he remembered, had during the past few days questioned him very cleverly, yet very closely, concerning himself and his family. Could there be any motive in that? In the silent hours of that night he became haunted by dark suspicions, but next morning when he awoke refreshed and went out in the autumn sunshine along the terrace, which gave a magnificent view of the great Hungarian plain for many miles, all his apprehensions were quickly dispelled.

Inwardly he laughed heartily at his own misgivings.

At eleven o’clock he drove with the Baron about three miles into the forest to a large high-up clearing—the spot which De Pelzel suggested should be the site of the new station. Indeed, two new log huts were already built for the transmitting and receiving gear, with a remote control to the generator plant.

Geoffrey, looking round upon the dense firs which screened them on every side save to the east, was surprised that such a site should have been chosen. But next second he recollected that the Baron knew nothing of wireless requirements.

“To tell you the truth,” Geoffrey said frankly, “I do not favour this spot at all. Results would be far better if we fitted the station somewhere else, for instance, near the terrace at the Schloss.”

“I quite imagine it, Mr. Falconer,” replied the eminently polite Baron. “But, unfortunately, my Government is desirous of possessing a confidential means of conversation between the two mining zones, and I have granted them permission to establish it here on my estate.”

“And the corresponding station?” asked Geoffrey.

“I will explain the situation of that later—when we have decided upon this.”

Falconer was disappointed. He saw that the aerial would be far too directional for the best results.
