Nurse Macdonald was a hundred years old. She used to sleep sitting all bent together in a great old leathern arm-chair with wings, her feet in a bag footstool lined with sheepskin, and many warm blankets wrapped about her, even in summer. Beside her a little lamp always burned at night by an old silver cup, in which there was something to drink.
Her face was very wrinkled, but the wrinkles were so small and fine and near together that they made shadows instead of lines. Two thin locks of hair, that was turning from white to a smoky yellow again, were drawn over her temples from under her starched white cap. Every now and then she woke, and her eyelids were drawn up in tiny folds like little pink silk curtains, and her queer blue eyes looked straight before her through doors and walls and worlds to a far place beyond. Then she slept again, and her hands lay one upon the other on the edge of the blanket; the thumbs had grown longer than the fingers with age, and the joints shone in the low lamplight like polished crab-apples.
It was nearly one o'clock in the night, and the summer breeze was blowing the ivy branch against the panes of the window with a hushing caress. In the small room beyond, with the door ajar, the girl-maid who took care of Nurse Macdonald was fast asleep. All was very quiet. The old woman breathed regularly, and her indrawn lips trembled each time as the breath went out, and her eyes were shut.
But outside the closed window there was a face, and violet eyes were looking steadily at the ancient sleeper, for it was like the face of Evelyn Warburton, though there were eighty feet from the sill of the window to the foot of the tower. Yet the cheeks were thinner than Evelyn's, and as white as a gleam, and the eyes stared, and the lips were not red with life; they were dead, and painted with new blood.
Slowly Nurse Macdonald's wrinkled eyelids folded themselves back, and she looked straight at the face at the window while one might count ten.
"Is it time?" she asked in her little old, faraway voice.
While she looked the face at the window changed, for the eyes opened wider and wider till the white glared all round the bright violet, and the bloody lips opened over gleaming teeth, and stretched and widened and stretched again, and the shadowy golden hair rose and streamed against the window in the night breeze. And in answer to Nurse Macdonald's question came the sound that freezes the living flesh.
That low-moaning voice that rises suddenly, like the scream of storm, from a moan to a wail, from a wail to a howl, from a howl to the fear-shriek of the tortured dead—he who has heard knows, and he can bear witness that the cry of the banshee is an evil cry to hear alone in the deep night. When it was over and the face was gone, Nurse Macdonald shook a little in her great chair, and still she looked at the black square of the window, but there was nothing more there, nothing but the night, and the whispering ivy branch. She turned her head to the door that was ajar, and there stood the girl in her white gown, her teeth chattering with fright.
