"Storm Over Skye is about two brothers on the island, Ruairidh the eldest, who is on leave from the Navy, and Niall, the younger and smaller for his age, at fifteen. Suspicion is poisoning the close-knit villagers trust, as one among them is slyly stealing sheep from the grazing field, and it is up to the level head of Ruairidh to solve the mystery, and restore order. All told by Niall, it is full of the flavor of mystery and small town life." -by Bookworm https://www.goodreads.com/book/show/1914191.Storm_over_Skye
