The Castle by Kafka

"The tower above him here - the only one visible - the tower of a house, as was now apparent, perhaps of the main building, was uniformly round, part of it graciously mantled in ivy, pierced by small windows that glittered in the sun, a somewhat maniacal glitter, and topped by what looked like an attic, with battlements that were irregular, broken, fumbling, as if designed by the trembling or careless hand of a child, clearly outlined against the blue.  It was as if a melancholy-mad tenant who ought to have been locked in the topmost chamber of his house had burst through the roof and lifted himself up to the gaze of the world."
