It was a hot close evening in mid May. There had scarcely been a breath of air all day and the night had brought no coolness. Fanny Sudlow sat in the dark at the open casement of her bedroom window, her hair unbound and a handkerchief soaked in vinegar laid across her forehead. She was suffering from one of those distressing headaches to which she had been more or less liable all her life. She heard the clock of St. Mary's strike eleven, and still she sat on, knowing of old that it was useless for her to go to bed till the pain should in some measure have abated. Her window looked into a corner of the old garden, in which, just then, the moon shone silvery bright. She had not been out of doors all day; her room felt so stifling and the garden looked so cool and inviting, that a strong desire came over her to get away from the close atmosphere of the house and pace its silent walks awhile in search of that nepenthe she was unable to find indoors. It was a desire which she let have its way.
Having tied back her hair, she flung a dark travelling cloak around her, the hood of which she could draw over her head were she so minded. Then she quitted her room and went lightly downstairs. Early hours were the rule at Loudwater House, and everybody had retired long ago. There were two exits from the house into the garden, one through the conservatory, the other by means of a glass door at the end of a side corridor. Fanny chose the latter. Having, with as little noise as possible, unlocked the door, she opened it and stepped out into the still moonlit night.
Making her way into the farther walks, she began to pace them slowly to and fro. Not a light shone anywhere in such windows of the house as were visible from the garden. The quietude was intense, but presently the silence was broken by the chiming of the quarter before twelve. The moonlight seemed to listen, and as the sound died away a low sigh breathed over the garden, and therewith half-opened leaves and bursting buds began to stir and whisper. They had awoke to the first kisses of the soft cool airs which had come as the avant-couriers of midnight.
Suddenly Fanny became as rigid as a statue. Her quick ears had caught a faint sound, as it might be of the crunching of gravel beneath someone's footsteps. Scarcely breathing, she listened. Yes, there it was again, nearer than before. Evidently someone was approaching in the direction where she was. Her first impulse was to hide herself. In a little trepidation she glanced around. Ah! there, close by her, was the well-house, as it was called. It was the one sheltered spot in the garden. A few swift noiseless strides and her form was lost among its shadows.
