The provided source text does not contain any biographical information regarding the writer Carleton B. Case. Instead, the reference material describes Carleton Castle, a five-story-high 15th-century ruin situated in a prominent position above the village of Lendalfoot on Carleton Bay, within the parish of Colmonell in the old district of Carrick, now known as South Ayrshire, Scotland.\n\nBecause the source is entirely limited to this brief geographical and historical description of a Scottish ruin, it is impossible to reconstruct the life, career, literary era, or notable works of Carleton B. Case. No details regarding his birth, death, nationality, or writing career are present in the provided reference, preventing the compilation of a standard author profile.
