we swept on our way, now in almost complete darkness, for the rolling clouds
obscured the moon.
We kept on ascending, with occasional periods of quick descent, but in the main
always ascending. Suddenly, I became conscious of the fact that the driver was
in the act of pulling up the horses in the courtyard of a vast ruined castle, from
whose tall black windows came no ray of light,and whose broken battlements
showed a jagged line against the sky.
