at a mark on
Dorothy's neck.

"It may have been the mark left there by Mrs. Hobbs' parrot," said
Dorothy, "or it may be one of the scratches I got when I fell over the
cliff. You see, I have been having a dreadful time. But when it is all
over I will have something worth talking about, to tell at camp. I
hope you will call upon us there. You would not be lonely if you knew
our boys."

"But if you are not Mary Harriwell, what can have become of her?"
asked the nurse with sudden conviction. "And I was sent to find her!"

"But you were directed to find me, were you not?" said Dorothy, in her
quick way of helping one out in distress. "I do not see how you could
be held responsible."

"But the girl--if she is still at large, she may be dead or injured,"
said Miss Bell, showing more and more that she did not believe Dorothy

Dorothy sprang up with more emotion than she wished to show, for her
every move was being watched.

"Well, the doctor will be here in the morning, and it is night now.
There would be no way of straightening this out until you are
positively identified."

"What a dreadfully lonely place Maine is! If I were near home--or
near any place where people would know me----" Dorothy was saying.

"Miss Bell, you are wanted at the 'phone," interrupted an attendant,
appearing at the door. "I'll stay until you get back."

Miss Bell left the room, and Dorothy did not look at the young woman
who had taken her place. There was something so humiliating about
being suspected of insanity!

"How do you like it here?" asked the newcomer.

"Very well," replied Dorothy, hurt by the sarcasm apparent in the
voice.

"Then why
