Haunted! Dr. McClary shrugged his weary shoulders. He wanted a ghost even less than he wanted a skeleton. Since he intended to have neither, he dismissed both possibilities and went back to work.

He was adjusting his table in the examination room, placing it where it would have the best light, when, out of the corner of his eye, he saw a figure move across the waiting room.

"Who's there?" he called. Surely the long-winded visitor had not returned!

There was no reply to his question.

"Who's there?" he called again. And again there was silence. He walked quickly into the waiting room. It was deserted. So was the hall.

"Strange," he said to himself. "I was sure I saw someone go into the waiting room, someone wearing a dark robe. I must really be tired to be having such hallucinations. It's time to go home!"

He locked the door and walked home through the late April twilight.

Several days later, late one afternoon, Dr. McClary saw the figure again. He had treated his last patient and was returning a reference book to the bookcase when he saw in the glass door the reflection of someone draped in a brown garment.

Dr. McClary whirled around to accost the intruder, but no one was in the room. He searched the adjoining areas immediately, but he found nothing. He was alone in his office. And, though he was reluctant to admit it to himself, he was a little frightened. Maybe not frightened exactly but certainly uneasy.

Catching glimpses of the elusive robed figure was not his only disquieting experience. On several occasions when he was alone in his office, Dr. McClary heard a peculiar clicking noise that sounded as if someone were hitting two marbles together. Though he searched everywhere, he could not find the source of the rhythmic clicking.
