n brandishing a long knife over
the head of a person in white.

The doctor lost no time in idle speculation.

"It's in that camp on the lower ledge," he said to himself as he dashed
down the path, and in some twenty minutes or more entered the living
room of Sunrise Camp.

It is not pleasant to think of what might have happened to Miss Helen
Campbell if the doctor's alert, intelligent eyes had not caught and
instantly comprehended the significance of the picture brought to him by
the telescope. How long might she have lain there unconscious, or how
dealt with the half-intoxicated Lupo if he had mounted the steps in
search of his wife? Then, as the hours slipped on and no human soul came
near to minister to her and comfort her, and she had finally realized
that her young people had never returned, how would she have endured
that second shock?

Fate had brought the doctor in the nick of time to perform an
inestimable service to the Motor Maids and to all those who knew and

And through this service to the friends of Miss Campbell, another was to
follow,--one filled with danger and interest, which would require all
the skill of his profession.

About ten o'clock Miss Campbell awoke, refreshed and rested. She took
the milk and bread with an appetite. Then she examined the stranger at

"They needn't have left me this enormous porch to myself. I know they
will hate sleeping down there. Can't Billie come and speak to me?"

"I am afraid he's sound asleep by now."

"He?" ejaculated the patient. "But, of course, how could you be expected
to know my young cousin by name. She is the tall girl with the gray
eyes. I think she is beautiful. Perhaps you might not--but you would--"

The doctor started. He had heard a stealthy step on the porch below.

"You will not think me impertinent if I ask you not to talk?" he said.
"Just a few more hours' quiet and you'll be quite fit. I'm going to
leave you a moment."
