I found, on my arrival, that Mackenzie was there before me. He was accompanied by one of the coroner's men and a police-constable. Two men who worked in the cemetery also came forward to assist. No one expressed the least surprise at our strange errand. Around Mackenzie's lips, alone, I read an expression of disapproval. Kensal Green is one of the oldest cemeteries which surround our vast Metropolis, and the Heathcotes' burying-place was quite in the oldest portion of this God's acre. It was one of the hideous, ancient, rapidly-going-out-of-date vaults. A huge brick erection was placed over it, at one side of which was the door of entrance. The earth was removed, the door of the vault opened, and some of the men went down the steps, one of them holding a torch, in order to identify the coffin. In a couple of minutes' time it was borne into the light of day. When I saw it I remembered poor Mrs. Heathcote's wild ravings. "A good, strong oak coffin, which wears well," she had exclaimed. Mackenzie and I, accompanied by the police-constable and the coroner's man, followed the bearers of the coffin to the mortuary. As we were going there, I turned to ask Mackenzie how his patient was. He shook his head as he answered me. "I fear the worst," he replied. "Mrs. Heathcote is very ill indeed. The fever rages high and is like a consuming fire. Her temperature was a hundred and five this morning." "I should recommend packing her in sheets wrung out of cold water," I answered. "Poor woman!--how do you account for this sudden illness, Mackenzie?" He shrugged his shoulders. "Shock of some sort," he answered. Then he continued: "If she really knew of this day's work, it would kill her off pretty quickly. Poor soul," he added, "I hope it may never reach her ears." [Illustration: "THEY UNSCREWED THE LID."] We had now reached the mortuary. The men who had borne the coffin on their shoulders lowered it on to a pair of trestles. They then took turn-screws out of their pockets, and in a business-like and callous manner unscrewed the lid. After doing this they left the mortuary, closing the door behind them. The moment we found ourselves alone, I said a word to the police-constable, and then going quickly up to the coffin, lifted the lid. Under ordinary circumstances, such a proceeding would be followed by appalling results, which need not here be described. Mackenzie, whose face was very white, stood near me. I looked at him for a moment, and then flung aside the pall which was meant to conceal the face of the dead. The dead truly! Here was death, which had never, in any sense, known life like ours. Mackenzie uttered a loud exclamation. The constable and the coroner's man came close. I lifted a bag of flour out of the coffin! There were many similar bags there. It had been closely packed, and evidently with a view to counterfeit the exact weight of the dead man.
