For almost two hours Dr. Willett waited vainly in Charles Ward’s library, watching the dusty shelves with their wide gaps where books had been removed, and smiling grimly at the paneled overmantel on the north wall, whence a year before the suave features of old Joseph Curwen had looked mildly down. After a time the shadows began to gather, and the sunset cheer gave place to a vague growing terror which flew shadow-like before the night. Mr. Ward finally arrived, and showed much surprise and anger at his son’s absence after all the pains which had been taken to guard him. He had not known of Charles’ appointment, and promised to notify Willett when the youth returned. In bidding the doctor good night he expressed his utter perplexity at his son’s condition, and urged his caller to do all he could to restore the boy to normal poise. Willett was glad to escape from that library, for something frightful and unholy seemed to haunt it; as if the vanished picture had left behind a legacy of evil. He had never liked that picture; and even now, strong-nerved though he was, there lurked a quality in its vacant panel which made him feel an urgent need to get out into the pure air as soon as possible.
