"Thank you for showing it to me." With an effort of will she moved
toward the bridge, but was impelled by a consciousness of the abruptness
of her departure to look back at him once--and smile, to experience
again the thrill of the current he sped after her. By lifting his hat, a
little higher, a little more confidently than in the first instance,
he made her leaving seem more gracious, the act somehow conveying an
acknowledgment on his part that their relationship had changed.

Once across the bridge and in the mill, she fairly ran up the stairs and
into the empty office, to perceive her bag lying on the desk where she
had left it, and sat down for a few minutes beside the window, her heart

seated at her typewriter the next morning she experienced a renewal of
the palpitation of the evening before, and at the sound of every step in
the corridor she started. Of this tendency she was profoundly ashamed.
And when at last Ditmar arrived, though the blood rose to her temples,
she kept her eyes fixed on the keys. He went quickly into his room: she
was convinced he had not so much as glanced at her.... As the days
went by, however, she was annoyed by the discovery that his continued
ignoring of her presence brought more resentment than relief, she
detected in it a deliberation implying between them a guilt
