I'm intrigued

I was looking up a historical figure (James Graham, 1st Marquess of Montrose, a Scottish general who was hanged, beheaded, and quartered for supporting Charles I during the War of the Three Kingdoms in 1650)--Battlefield Band has a song called 'Montrose'. Going down that rabbit hole, I found a book by John Buchan [novelist and former Governor General of Canada] called Witch Wood, which sounded promising and put it in as an interlibrary loan request with the Lexington public library. Montrose only makes a small appearance in it, but the story sounded compelling, the story of a clergyman who discovers Scottish witchcraft/paganism being practised and suffers from ensuing politics in the 17th century. It'll probably come from the University of Kentucky, as their library has it. I have a UK library card, but for residents of Kentucky, they expire after a year, and mine is likely expired. The thing I'm most interested in is that in the over 300-page story, a lot of the dialogue is in Scots, which I am interested in, having a lot of Scottish ancestry.
