St. Ives by Robert Louis Stevenson

The lawyer was scarce gone before I remembered many omissions; and chief among these, that I had neglected to get Mr. Burchell Fenn's address. Here was an essential point neglected; and I ran to the head of the stairs to find myself already too late. The lawyer was beyond my view; in the archway that led downward to the castle gate, only the red coat and the bright arms of a sentry glittered in the shadow; and I could but return to my place upon the ramparts.

I am not very sure that I was properly entitled to this corner. But I was a high favourite; not an officer, and scarce a private, in the castle would have turned me back, except upon a thing of moment; and whenever I desired to be solitary, I was suffered to sit here behind my piece of cannon unmolested. The cliff went down before me almost sheer, but mantled with a thicket of climbing trees; from farther down, an outwork raised its turret; and across the valley I had a view of that long terrace of Princes Street which serves as a promenade to the fashionable inhabitants of Edinburgh. A singularity in a military prison, that it should command a view on the chief thoroughfare!
