"Next, the discoveries made in the room where the murder was committed, and certain other indications found outside, did not fit in with the police case against Penreath. Superintendent Galloway's reconstruction of the crime, after he had seen the body and examined the inn premises, did not account for the existence of all the facts. There were circumstances and clues which were not consistent with the police theory of the murder. The probability of the inference that Penreath was the murderer was not increased by the discoveries we made. I am aware that absolute proof is not essential to conviction in a case of circumstantial evidence, but, on the other hand, to ignore facts which do not accord with a theory is to go to the other extreme, for by so doing you are in danger of excluding the possibility of any alternative theory. "On the other hand, when I sought to account for the crime by any other hypothesis I found myself puzzled at every turn. The presence of two persons in the room was the baffling factor. The murderer had entered through the window in the storm, lighted the tallow candle which he brought with him, walked straight to the bed and committed the murder. Then he had waited till the rain ceased before carrying the body downstairs to the pit. But what about the second person--the person who had carried the wax candle and dropped spots of grease underneath the broken gas globe? Had he come in at a different time, and why? Why had he sought to light the gas, when he carried a candle? Why had he--as I subsequently ascertained--left the room and gone downstairs to turn on the gas at the meter? "Eliminating Penreath for the time being, I tried next to fit in the clues I had discovered with two alternative theories. Had the murder been committed from outside by a villager, or by somebody in the inn? There were possibilities about the former theory which I pointed out to Superintendent Galloway, who subsequently investigated them, and declared that there was no ground for the theory that the murder had been committed from outside. The theory that the murder had been committed by somebody inside the inn turned my attention to the inmates of the inn. Excluding Penreath for the time being, there were five inmates inside the walls the night the murder was committed--the innkeeper, his daughter, his mother, the waiter, and Ann, the servant. The girl could hardly have committed the murder, and could certainly not have carried away the body. The old mad woman might have committed the murder if she could have got out of her room, but she could not have carried the body to the pit--neither could the servant. By this process of elimination there remained the landlord and the deaf waiter.
