shouted Mr. Racer, as he stepped out into the hall
from his room, nearest to which the electric switch was, and flashed on
the incandescents. "Don't run into danger."

Andy was now following his brother, having caught up a heavy fishing
rod, bound together, as a substitute for a club.

"Paul, are you hurt?" cried Frank again, and by this time he was at the
room door of the lad who had been so alarmed by the midnight visitor.

"No, I--I'm all right," was the panting answer, and Paul met Frank at
the portal, throwing the gleam of the hand electric all about. Frank
turned on the regular light in Paul's room, and looked around. The
wire mosquito screen was raised, showing how the intruder had gained
entrance. By this time Andy and Mr. Racer had joined Frank and Paul,
and Mrs. Racer had been assured that whoever had entered was now
outside the house.

"But what was it? Who was it?" demanded Mr. Racer.

"I--I--" began Paul, who was trembling from fright.

"I know who it was, I saw him!" interrupted Frank. "It was the same

"Yes!" suddenly exclaimed Paul. "I--I know him! His name is--"

"That's what we want to know--who is he?" interrupted Andy eagerly.

"He is--his name is--Oh, why can't I remember?" cried poor Paul,
passing his hand over his forehead in despair. "I thought it was
coming to me, but it's faded away again! Oh, why can't I recall who he
is? Then I know the mystery would be solved. But I can't--it's
all--so--so hazy. Only I know that this man had something to do with
me--and, yes, I'm beginning to recall it now--my father also. He
wanted to harm me--or was it my father? I can't--"

"Now look here," broke in Mr. Racer kindly, "this won't do, you know.
You must calm yourself, Paul. I can't let you ex
