He turned sharply at the words, a pencil in his hand, surprise on his face. A good face; for its old gay careless look had departed for ever, and the dark blue eyes--darker even than of yore--wore a serious gravity that never left them, a gravity born of remorse. The face was older than the figure, and not in the least like Cyril Thornycroft's; it looked fully its seven-and-twenty years--nay, looked nearer thirty; but all its expression was merged in surprise. No wonder; to see a beautiful girl in blue silk, with blue ribbons in her fair hair, standing there; when he had only expected the professor, in his old threadbare coat and spectacles. It was Robert Hunter. "I beg your pardon," he said, coming forward. "Can I do anything for you?" "I thought Dr. Macpherson was here. I came to see him." Never losing her calm self-possession on any occasion, as so many young ladies do on no occasion at all, Miss Thornycroft stepped up to the side glass cases to examine the curiosities, talking as easily to him as though she had known him all her life. Without being in the least free, there was an openness of manner about her, an utter absence of tricks and affectation, a straightforward independence, rather remarkable in a young lady. For Robert Hunter it possessed a singular charm. Before the professor came in, who had forgotten himself down in his cellar, where he had gone after a cherished specimen in the frog line; before Mr. Hunter had pointed out to her a quarter of the new acquisitions in the glass cases--animal, vegetable, and mineral--they knew all about each other: that he was Susan Hunter's brother, and that she was Miss Thornycroft of Coastdown. At mention of her name, a brief vision connected with the past floated across Robert Hunter's brain--of a certain summer evening when he was returning to Guild with his poor young wife, and saw the back of a high open carriage bowling away from his sister's gate, which he was told contained Mr. and Miss Thornycroft. Never since that had he heard the name or thought of the people. "Do you know, when I came into the room just now, and you were standing with your back to me, I nearly took you for one of my brothers. At the back you are just like him." Robert Hunter smiled slightly. "And not in the face?" "Not at all--except, perhaps, a little in the forehead. Cyril has hazel eyes and small features. The hair is exactly like his, the same colour, and grows just as his does in front, leaving the forehead square. If you were to hide your face, showing only the top of the forehead and the hair, I should say you were Cyril." The professor appeared, and they went into the more habitable part of the house. Robert had not seen his sister since she was a little girl; he had not seen Anna since they parted at Guild. It was altogether an acceptable meeting; but he looked at Anna's face somewhat anxiously. "Have you been working very much, Anna?" he took occasion to ask, drawing her for a moment aside.
