Mrs Oliphant 
It was a Lover and His Lass [EPUB ebook] 

Excerpt: "There stands in one of the northern counties of Scotland, in the midst of a wild and wooded landscape, with the background of a fine range of hills, and in the vicinity of a noble trout-stream, a great palace, uninhabited and unfinished. It is of the French-Scottish style of architecture, but more French than Scotch — a little Louvre planted in the midst of a great park and fine woods, by which, could a traveller pass, as in the days of Mr. G.P.R. James, on a summer evening when the sun had set, and find himself suddenly face-to-face with such an edifice amid such a solitude, the effect even upon the most hardened British tourist would be something extraordinary."
