After a while they went upstairs and hung holly in the passages.
Seymour had turned his back to her and was balanced on a little ladder, when he heard her utter a sharp little cry.
"The nursery door's open," she said.

He turned, and saw very clearly, against the half-light, her startled eyes.

Her hands were pressed against her dress and holly had fallen at her feet.

He saw, too, that the nursery door was ajar.
"I locked it myself, yesterday; you saw me." She gasped as though she had been running, and he saw that her face was white.
He moved forward quickly and pushed open the door.

The room itself was lightened by the gleam from the passage and also by the moonlight that came dimly through the window.
