and began to clear out the stoves in the other lecture-rooms.
When he reached Webster's he was surprised to find that both doors, that
of the lecture room and that of the lower laboratory, were either locked
or bolted. He could hear nothing but the running of water in one of the
sinks. About half-past five Littlefield saw the Professor coming down
the back stairs with a lighted candle in his hand. Webster blew out the
candle and left the building. Late that night Littlefield again tried
the Professor's doors; they were still fastened. The janitor was
surprised at this, as he had never known such a thing to happen before.

On Saturday, the 24th, though not lecturing that day, the Professor came
to the College in the morning. He told Littlefield to light the stove
in the lower laboratory. When Littlefield made to pass from the
lecture-room into the Professor's private room at the back, and so down
by the private stairs to the lower laboratory, the Professor stopped him
and told him to go round by the door in front of the building. The whole
of that day and Sunday, the Professor's doors remained fast. On Sunday
evening at sunset Littlefield, who was talking with a friend in North
Grove Street, the street that faces the College, was accosted by
Webster. The Professor asked him if he recollected Parkman's visit
to the College on Friday, the 23rd, and, on his replying in the

seemed unable to look him in the face, his manner was confused, his face

During the whole of Monday, except for a visit from Mr. Parkman Blake,
Professor Webster was again locked alone in his laboratory. Neither
that night, nor early Tuesday morning, could Littlefield get into
the Professor's rooms to perform his customary duties. On Tuesday the
Professor lectured at twelve o'clock, and later received the visit of
the police officers that has been described already. At four o'clock
that afternoon, the Professor's bell rang. Littlefield answered it.
The Professor asked the janitor whether he had bought his turkey for
Thanksgiving Day, which was on the following Thursday. Littlefield said
that he had not done so yet. Webster then handed him an order on his
provision dealer. "Take that," he said, "and get a nice turkey; perhaps
I shall want yo
