While he ate alone, Harry tried to summarize his facts.
First: a messenger was due that night. That, at least was tangible.
Second: one could not use the radio here after eight o’clock. Why?
He remembered that static had disturbed the program; yet he had no idea what the cause might have been.
Some mystery lay in the tower of this house. Beings — or whatever they were — emerged from the lake and came to the tower.
The tower demanded investigation. Yet Harry knew that he must proceed with utmost caution. For Professor Whitburn had told him emphatically that he must not go anywhere in the house without specific instructions. That definitely eliminated the tower.
Now, as he considered everything in the sober light of day, Harry wondered what had happened in the house while he had been outside, watching the strange events.
Had his absence been noted?
That was quite probable. He had stepped out merely for a breath of air. He had been gone at least half an hour. Any one of the three men might have entered the living room while he had been gone.
Harry had not noted the time at which the phenomena had occurred; but he knew that it must have been considerably after nine o’clock. Probably along about ten thirty.
