The Cathedral by Hugh Walpole

The cloud seemed to creep like smoke from the funnel of the Cathedral tower. The sun was setting in a fiery wreath of bubbling haze, shading in rosy mist the mountains of grey stone. The little cloud, at first in the shadowy air light green and shaped like a ring, twisted spirally, then, spreading, washed out and lay like a pool of water against the smoking sunset.

Green like the Black Bishop's ring. Lying there, afterwards, until the orange had faded and the sky, deserted by the sun, was milk-white. The mists descended. The Cathedral chimes struck five. February night, cold, smoke-misted, enwrapped the town.
