icked it up, read what
was written on it, and stood for a moment motionless, his eyes fixed on
the carpet, his lips writhing.

How long he stood there he did not know, but presently he was aroused by
the sound of footsteps. He listened. Some one--the rustling of a
dress--was approaching the room. He slipped the note into the book and
replaced the volume on the pedestal, and quickly stepped behind the
portiere curtains.

He expected his wife. Should he come forward and confront her? His stern
face grew red with shame--for her, for himself. Then, with a sudden leap
of the heart, with a sensation of relief which was absolutely painful in
its intensity, he saw Nell enter the room and go straight to the
pedestal. Her face was pale and troubled, and she looked round with what
seemed to him a guilty expression in the gray eyes. Then she opened the
book as he had done, but, as if she expected to find something, took out
the note, and after a moment of hesitation read it. He saw her face
flush hotly, then grow white, and her hand go out to the pedestal as if
for support. For a moment she stood as motionless as he had done, then
she thrust the note into her pocket, dropped the book from her hand--it
fell on the floor unregarded by her--and slowly left the room.

Wolfer passed his hand over his brow with a bewildered air, then, as if
obeying an irresistible impulse, he followed her up the stairs.

Quietly but slowly. He knew that she had not seen him, did not know that
he was following her, and he waited at the end of the corridor,
watching her with a heart throbbing with an agony of anxiety. Was she
going to carry the note to his wife? But she did not even hesitate at
the door of Lady Wolfer's room, but went straight to her own, and he
heard the key turn as she locked it.

The sweat was standing in great drops upon his forehead, and he put up a
trembling hand and wiped them away as he looked toward his wife's door.
Should he go in and question her? Should he ask her straightly whether
the note was intended for her or Nell? It seemed too horrible to suspect
the girl who had seemed innocence and purity itself, and yet had he not
seen her go straight for the book, as if she had known that it was there
waiting for her?

Like a man in a dream he went down to the library, and, locking the
door, flung himself into a chair, and buried his face in his hands. What
was he to think?
