Another relative of Dr. Parkman, his nephew, Mr. Parkman Blake, in the course of inquiries as to his uncle's fate, thought it right to see Webster. Accordingly he went to the college on Monday, the 26th, about eleven o'clock in the morning. Though not one of his lecture days, the janitor Littlefield informed him that the Professor was in his room. The door of the lecture-room, however, was found to be locked, and it was only after considerable delay that Mr. Blake gained admittance. As he descended the steps to the floor of the lecture-room Webster, dressed in a working suit of blue overalls and wearing on his head a smoking cap, came in from the back door. Instead of advancing to greet his visitor, he stood fixed to the spot, and waited, as if defensively, for Mr. Blake to speak. In answer to Mr. Blake's questions Webster described his interview with Dr. Parkman on the Friday afternoon. He gave a very similar account of it to that he had already given to Mr. Francis Parkman. He added that at the end of their interview he had asked the Doctor for the return of the mortgage, to which the latter had replied, "I haven't it with me, but I will see it is properly cancelled." Mr. Blake asked Webster if he could recollect in what form of money it was that he had paid Dr. Parkman. Webster answered that he could only recollect a bill of L20 on the New Zealand Bank: pressed on this point, he seemed to rather avoid any further inquiries. Mr. Blake left him, dissatisfied with the result of his visit.
One particular in Webster's statement was unquestionably strange, if not incredible. He had, he said, paid Parkman a sum of L90, which he had given him personally, and represented the Doctor as having at their interview promised to cancel the mortgage on the collection of minerals which Webster had given as security for the loan of L490 that had been subscribed by Parkman and four of his friends. Now L120 of this loan was still owing. If Webster's statement were true, Parkman had a perfect right to cancel Webster's personal debt to himself; but he had no right to cancel entirely the mortgage on the minerals, so long as money due to others on that mortgage was yet unpaid. Was it conceivable that one so strict and scrupulous in all monetary transactions as Parkman would have settled his own personal claim, and then sacrificed in so discreditable a manner the claims of others, for the satisfaction of which he had made himself responsible?
There was yet another singular circumstance. On Saturday, the 24th, the day after his settlement with Parkman, Webster paid into his own account at the Charles River Bank the cheque for L18, lecture fees, handed over to him by the agent Pettee just before Dr. Parkman's visit on the Friday. This sum had not apparently gone towards the making up of the L90, which Webster said that he had paid to Parkman that day. The means by which Webster had been enabled to settle this debt became more mysterious than ever.
On Tuesday, November 27, the Professor received three other visitors in his lecture-room. These were police officers who, in the course of their search for the missing man, felt it their duty to examine, however perfunctorily, the Medical College. With apologies to the Professor, they passed through his lecture room to the laboratory at the back, and from thence, down the private stairs, past a privy, into the lower laboratory. As they passed the privy one of the officers asked what place it was. "Dr. Webster's private lavatory," replied the janitor, who was conducting them. At that moment Webster's voice called them away to examine the store-room in the lower laboratory, and after a cursory examination the officers departed.
The janitor, Ephraim Littlefield, did not take the opportunity afforded him by the visit of the police officers to impart to them the feelings of uneasiness; which the conduct of Professor Webster during the last three days had excited in his breast. There were circumstances in the Professor's behaviour which could not fail to attract the attention of a man, whose business throughout the day was to dust and sweep the College, light the fires and overlook generally the order and cleanliness of the building.
Littlefield, it will be remembered, had seen Dr. Parkman on the Monday before his disappearance, when he visited Webster at the College, and been present at the interview, in the course of which the Doctor told Webster that "something must be done." That Monday morning Webster asked Littlefield a number of questions about the dissecting-room vault, which was situated just outside the door of the lower laboratory. He asked how it was built, whether a light could be put into it, and how it was reached for the purpose of repair. On the following Thursday, the day before Parkman's disappearance, the Professor told Littlefield to get him a pint of blood from the Massachusetts Hospital; he said that he wanted it for an experiment. On the morning of Friday, the day of Parkman's disappearance, Littlefield informed the Professor that he had been unsuccessful in his efforts to get the blood, as they had not been bleeding anyone lately at the hospital. The same morning Littlefield found to his surprise a sledge-hammer behind the door of the Professor's back room; he presumed that it had been left there by masons, and took it down to the lower laboratory. This sledge-hammer Littlefield never saw again. About a quarter to two that afternoon Littlefield, standing at the front door, after his dinner, saw Dr. Parkman coming towards the College. At two o'clock Littlefield went up to Dr. Oliver Wendell Holmes' room, immediately above Professor Webster's, to help the Doctor to clear his table after his lecture, which was the last delivered that day. About a quarter of an hour later he let Dr. Holmes out, locked the front door 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 affirmative, the Professor described to him their interview and the repayment of his debt. Littlefield was struck during their conversation by the uneasiness of the Professor's bearing; contrary to his habit he seemed unable to look him in the face, his manner was confused, his face pale.
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 you to do some odd jobs for me." Littlefield thanked him, and said that he would be glad to do anything for him that he could. The janitor was the more surprised at Webster's generosity on this occasion, as this turkey was the first present he had received at the Professor's hands during the seven years he had worked in the College. Littlefield saw the Professor again about half-past six that evening as the latter was leaving the College. The janitor asked him if he wanted any more fires lighted in his rooms, because owing to the holidays there were to be no further lectures that week. Webster said that he did not, and asked Littlefield whether he were a freemason. The janitor said "Yes," and with that they parted.
Littlefield was curious. The mysterious activity of the Professor of Chemistry seemed to him more than unusual. His perplexity was increased on the following day. Though on account of the holidays all work had been suspended at the College for the remainder of the week, Webster was again busy in his room early Wednesday morning. Littlefield could hear him moving about. In vain did the janitor look through the keyhole, bore a hole in the door, peep under it; all he could get was a sight of the Professor's feet moving about the laboratory. Perplexity gave way to apprehension when in the course of the afternoon Littlefield discovered that the outer wall of the lower laboratory was so hot that he could hardly bear to place his hand on it. On the outer side of this wall was a furnace sometimes used by the Professor in his chemical experiments. How came it to be so heated? The Professor had told Littlefield on Tuesday that he should not be requiring any fires during the remainder of the week.
The janitor determined to resolve his suspicions. He climbed up to the back windows of the lower laboratory, found one of them unfastened, and let himself in. But, beyond evidences of the considerable fires that had been kept burning during the last few days, Littlefield saw nothing to excite peculiar attention. Still he was uneasy. Those he met in the street kept on telling him that Dr. Parkman would be found in the Medical College. He felt that he himself was beginning to be suspected of having some share in the mystery, whilst in his own mind he became more certain every day that the real solution lay within the walls of Professor Webster's laboratory. His attention had fixed itself particularly on the lavatory at the foot of the stairs connecting the upper and lower laboratories. This room he found to be locked and the key, a large one, had disappeared. He recollected that when the police officers had paid their visit to the college, the Professor had diverted their attention as they were about to inspect this room. The only method by which, unknown to the Professor and without breaking open the door, Littlefield could examine the vault of this retiring room was by going down to the basement floor of the college and digging a hole through the wall into the vault itself. This he determined to do.
