ntil 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.

The ghostly chase went on for a full half-hour, Dick having nothing to
serve him save an occasional light footfall. There was one period of
more than half an hour when he lost the fugitive entirely. He wandered
up to the second floor and then back again. There, in a room that had
been the library, he caught a glimpse of the man. But the figure was so
shadowy that he could tell nothing about him.

"Halt!" cried Dick, snatching out his pistol. But when he leveled it
there was nothing to aim at. The figure had melted away, or rather it
had flitted through another door. Dick followed, chagrined. The stranger
seemed to be playing with him. Obviously, it was some one thoroughly
acquainted with the house, and that brought to Dick's mind the thought
that he himself, instead of the other man, was the stranger there.

He came at last to a passage which led to the kitchen, a great room,
because many people were often guests at Bellevue, and here he stopped
short, while his heart suddenly beat hard. A distinct odor coming from
different points suddenly assailed his nostrils. He had smelled it too
often in the last two years to be mistaken. It was smoke, an
