Dick looked down the long piazza, so long that the men at either end of it were hidden by darkness. The tall trees in the grounds were nodding before the wind, and the lightning flashed incessantly in the southwest. The thunder was not loud, but it kept up a continuous muttering and rumbling. The rain was coming in fitful gusts, but he knew that it would soon drive hard and for a long time.
Everybody within Dick’s area of vision was sound asleep, except himself. Colonel Winchester lay with his head on his arm and his slumber was so deep that he was like one dead. Warner had not stirred a particle in the last half-hour. Dick was angry at himself because he could not sleep. Let the storm burst! It might drive on the wide roof of the piazza and the steady beating sound would make his sleep all the sounder and sweeter. He recalled, as millions of American lads have done, the days when he lay in his bed just under the roof and heard hail and sleet drive against it, merely to make him feel all the snugger in the bed with his covers drawn around him.
The fitful gusts of rain ceased, and then it came with a steady pour and roar, driving directly down, thus leaving the men on the outer edges of the piazzas untouched and dry. Still, Dick did not sleep, and at last he arose and walked softly into the house. Here the sense of danger grew stronger. He was reminded again of his early boyhood, when some one blindfolded was told to find a given object, and the others called “hot” when he was near or “cold” when he was away. He was feeling hot now. That inherited sense, the magnetic feeling out of the past, was warning him.
Dick felt sure that some one not of their regiment was in the building. He neither saw nor heard the least sign of a presence, but he was absolutely certain that he was not alone within Bellevue. Since the lightning had ceased it was pitchy dark inside. There was a wide hall running through the building, with windows above the exits, but he saw nothing through them save the driving rain and the dim outline of the threshing trees.
He turned into one of the side rooms, and then he paused and pushed himself against the wall. He was sure now that he heard a soft footstep. The darkness was so intense that it could be felt like a mist. He waited but he did not hear it again, and then he began to make his way around the wall, stepping as lightly as he could.
He had gone through most of the rooms at their arrival and he still retained a clear idea of the interior of the house. He knew that there was another door on the far side of the chamber in which he stood, and he meant to follow the wall until he reached it. Some one had been in the room with him and Dick believed that he was leaving by the far door.
While he heard no further footsteps he felt a sudden light draught on his face and he knew that the door had been opened and shut. He might go to Colonel Winchester and tell him that a lurking spy or somebody of that character was in the house, but what good would it do? A spy at such a time and in such a place could not harm them, and the whole regiment would be disturbed for nothing. He would follow the chase alone.
He found the door and passed into the next room. Its windows opened upon the southern piazza and two or three shutters were thrown back. A faint light entered and Dick saw that no one was there but himself. He could discern the dim figures of the soldiers sleeping on the piazza and beyond a cluster of the small pines grown on lawns.
Dick felt that he had lost the trail for the time, but he did not intend to give it up. Doubtless the intruder was some one who knew the house and who was also aware of his presence inside. He also felt that he would not be fired upon, because the stranger himself would not wish to bring the soldiers down upon him. So, with a hand upon his pistol butt, he opened the side door and followed once more into the darkness.
