He was a tall man, wearing a cap and a grey Scotch plaid scarf. The cap, which had a peak to it, appeared to be tied down over his ears, and the scarf was worn in a droll fashion, one at least that Sara had never seen in Hallingham. It was put lengthways over the shoulders, as a lady puts on a scarf; it came down to the waist behind, and was held very much up to the neck in front. Sara naturally looked at the man, looked keenly with a view of distinguishing his features. In her sympathy with the sick, she thought to learn, by him, who was ill that night and wanted her father. But she was unable to do this, and the first thought that struck upon her as curious was, that a man should be so completely wrapped up on that genial night. The next curious thing that struck her was--the man's movements. He had come up to the gate with very quick steps--as messengers from the sick often did come--opened it, and gave a sort of dart or spring to his right, which brought him under the shade of the laurels and hid him from the moonlight. There he stopped, reconnoitring the house, so far as could be seen, but really it required a quick eye to distinguish him at all from the dark shrubs. That was not precisely the way in which night applicants came to Dr. Davenal's house; and Sara, very much astonished, rose quietly from her seat, to see the better. He came on at last, creeping close to the shrubs, stooping under their shade, until he gained Dr. Davenal's window. With all Sara's endeavours to look, she there lost sight of him, because he was beneath, but she heard a gentle tapping at the window. Not the quick imperative noise of one in haste, demanding instant attention, but a covert, stealthy tapping, which seemed afraid of being heard. More and more astonished, Sara leaned out further; but she could not lean far enough to see. The window was opened instantly; therefore it was to be supposed that Dr. Davenal had not retired from the room; that his light had probably guided the stranger to apply at the window, instead of at the door. The first sound, after the opening of the window, was a warning hush-sh-sh-sh! but whether it came from the applicant or from her father she could not tell. A short colloquy followed, only a word or two in the most covert tones, and then Dr. Davenal went to the front door and admitted the visitor. Sara sat down overwhelmed with amazement.
