"Devotedly yours,
Charley Wright."

It was this photograph that had caught Dunn's eyes. Both it and the
writing and the signature he recognized, and his look was very stern,
his eyes as cold as death itself, as slowly, slowly he pushed back the
door of the room another inch or so.

CHAPTER V. A WOMAN AND A MAN

The girl stirred. It was as though some knowledge of the slow opening of
the door had penetrated to her consciousness before as yet she actually
saw or heard anything.

She rose to her feet, drying her eyes with her handkerchief, and as she
was moving to a drawer near to get a clean one her glance fell on the
partially-open door.

"I thought I shut it," she said aloud in a puzzled manner.

She crossed the floor to the door and closed it with a push from her

When he had it once more so far open that he could see within, he bent
forward to look. The girl was beginning her preparations for the night
now. She had assumed a long, comfortable-looking dressing-gown and,
standing in front of the mirror, she had just finished brushing her hair
and was beginning to fasten it up in a long plait. He could see her face
in the mirror; her deep, sad eyes, swollen with crying, her cheeks still
tear-stained, her mouth yet quivering with barely-repressed emotion.

He was still watching her when, as if growing uneasy, she turned her
head and glanced over her shoulder, and though he moved back so quickly
that she did not catch sight of him, she saw that the door was open once
more.

"What can be the matter with the door?" she exclaimed aloud, and
she crossed the room towards it with a quick and somewhat impatie
