Detective Stone had searched for the ghost all morning, in vain. About two hours after lunch, Josephine, the housekeeper, pulled him aside and told him:

"There's a storm brewing. I can feel it in my knees."

After telling him this, she resumed working. The old lady was obviously not quite right in the head as the sky was perfectly clear. A few minutes later, the detective began to wonder if somehow the ghost could conjure a storm. His suspicions proved to be correct as, about an hour later, Scott saw a white figure fly around the castle before it starting raining heavily. The rain was accompanied by lightning and thunder. During the storm, Detective Stone saw the old housekeeper again.

"I told you so. My knees never lie," she said.

Like before, after talking to him, she continued working as if she hadn't said anything. The detective went outside to see if anything odd was going on with the rain. It seemed like normal rain. But why would the ghost conjure a storm? What's the use? Unless... No! But maybe? It could. But if the ghost was a Sluagh why would it be attacking Lord Addington? Unless Lord Addington was sick.

As he believes in the supernatural, Detective Stone owns several books about it. At this moment, he remembered a specific chapter about sluaghs.

Sluaghs

In Irish and Scottish folklore, the Sluagh were the spirits of the restless dead. Sometimes they were seen as sinners, or generally evil people who were welcome in neither heaven nor hell, nor in the Otherworld, who had also been rejected by the Celtic deities and by the earth itself. Whichever the underlying belief, they are almost always depicted as troublesome and destructive. They were seen to fly in groups like flocks of birds, coming from the west, and were known to try to enter the house of a dying person in an effort to carry the soul away with them. West-facing windows were sometimes kept closed to keep them out. Some consider the Sluagh to also carry with them the souls of innocent people who were kidnapped by these destructive spirits.

A Sluagh, separated from its flock, trying to enter Lord Addington's house because he is sick and dying. Of course! That would explain why the west side of the house is abandoned. How long has this Sluagh been here?

Detective Stone went back in the house to inquire upon Lord Addington's medical condition.
