His usual sleeping place was in a low gallery below stairs; but it so happened that there was a closet beside Charles's bed in which there was neither bed nor furniture of any kind, with the exception of a single chair.

The door between them had, as is usual, two panes of glass in; it, through which any person in the dark could see what happened in the room in which Charles slept.
Barney locked the door on the inside, and it was well that he did so, for in a short time Woodward came in, with a guilty and a stealthy pace, and having looked, like a murderer, about the room, he approached the closet door and tried to open it; but finding that it was locked his apprehensions vanished, and he deliberately, on seeing that his brother was asleep, took a bottle out of his pocket, and having poured about a wine-glassful of the poison into the small jug which contained the usual drink of the patient, he left the room, satisfied that, as soon as his brother awoke, he would take the deadly draught.

When he departed, Barney came out, and having substituted another for it--for there was a variety of potions on the sick table--he, too, stealthily descended the stairs, and going to the dog-kennel deliberately administered the pernicious draught to the dog which Woodward had insisted was unwell.
He happily escaped all observation, and accomplished his plan without either notice or suspicion.

He stayed in the kennel in order to watch the effects of the potion upon the dog, who died in the course of about fifteen minutes after having received it.
"Now," said Barney, "I think I have my thumb upon him, and it will go hard with me or I will make him suffer for this hellish intention to murder his brother.

Mr.Greatrakes is a man of great wealth and high rank; he is, besides, a magistrate of the county, and, please God, I will disclose to him all that I have seen and suspect." Barney, under the influence of these feelings, went to bed, satisfied that he had saved the life of Charles Lindsay, at least for that night, but at the same time resolved to bring his murderous brother to an account for his conduct..
