The Literary Sense by Edith Nesbit

SHE opened the window, at which no light shone. All the other windows were darkly shuttered. The night was still: only a faint breath moved among the restless aspen leaves. The ivy round the window whispered hoarsely as the casement, swung back too swiftly, rested against it. She had a large linen sheet in her hands. Without hurry and without delayings she knotted one corner of it to the iron staple of the window. She tied the knot firmly, and further secured it with string. She let the white bulk of the sheet fall between the ivy and the night, then she climbed on to the window-ledge, and crouched there on her knees. There was a heart-sick pause before she grasped the long twist of the sheet as it hung -- let her knees slip from the supporting stone and swung suddenly, by her hands. Her elbows and wrists were grazed against the rough edge of the window-ledge -- the sheet twisted at her weight, and jarred her shoulder heavily against the house wall.

Her arms seemed to be tearing themselves from their sockets. But she clenched her teeth, felt with her feet for the twisted ivy stems on the side of the house, found foothold, and the moment of almost unbearable agony was over. She went down, helped by feet and hands, and by ivy and sheet, almost exactly as she had planned to do. She had not known it would hurt so much -- that was all. Her feet felt the soft mould of the border: a stout geranium snapped under her tread. She crept round the house, in the house's shadow -- found the gardener's ladder -- and so on to the high brick wall. From this she dropped, deftly enough, into the suburban lane: dropped, too, into the arms of a man who was waiting there. She hid her face in his neck, trembling, and said, "Oh, Harry -- I wish I hadn't! " Then she began to cry helplessly.
