"In beer?"—"Yes."
Here a spectator interrupted with the remark that the deceased was never known to drink beer, but had been fond of purl, and the question was hastily put:
"Was it not in purl?"—"Yes."
"How long did you live after taking it?"—Three knocks, held to mean three hours.
"Did Carrots" (her maid) "know of your being poisoned?"—"Yes."
"Did you tell her?"—"Yes."
"How long was it after you took it before you told her?" One knock, for one hour.
Here was something tangible, and Knight went to work with a will to refute the terrible charge brought by the invisible accuser. As reported in The Daily Gazetteer, which had promised that "the reader may expect to be enlightened from time to time to the utmost of our power in this intricate and dark affair," the maid Carrots was found, and from her was procured a sworn statement that Mrs. Knight had said not a word to her about being poisoned; that, indeed, she had become unconscious twelve hours before her death and remained unconscious to the end. The physician and apothecary who had attended her made affidavit to the same effect, and described the fatal nature of her illness. It was further shown that her death at most benefited Knight by not more than a hundred pounds, of which he had no need, as he was of independent means.
Altogether, he would seem to have cleared himself effectually. Still the knocking continued, and night after night the accusation was repeated. He now resorted, therefore, to a radical step to convince the public that he was the victim of a monstrous fraud.
Asserting that little Miss Parsons herself produced the mysterious sounds, and that she did so at the instigation of her father, he secured an order for her removal to the house of a friend of his, a Clerkenwell clergyman. Here a decisive failure was recorded against the ghost. It had promised that it would knock on the coffin containing Mrs. Knight's remains; and about one o'clock in the morning, after hours of silent watching, during which the spirit gave not a sign of its presence, the entire company adjourned to the church. Only one member was found of sufficient boldness to plunge with Knight into the gloomy depths where the dead lay entombed; and that one bore out his statement that never a knock had been heard. The girl was urged to confess, but persisted in her assertions that the ghost was in nowise of her making.
