They ran into the middle of the street to look up at the nursery window; and, yes, it was still shut, but the room was ablaze with light, and most heart-gripping sight of all, they could see in shadow on the curtain three little figures in night attire circling round and round, not on the floor but in the air.

Not three figures, four!

In a tremble they opened the street door. Mr. Darling would have rushed upstairs, but Mrs. Darling signed to him to go softly. She even tried to make her heart go softly.
