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.
