The Mirror of the Sea by Joseph Conrad, Fiction (Paperback) (ISBN-13: 9781592244164)

On my first voyage as chief mate with good Captain MacW-------- I remember that I felt quite flattered and went blithely about my duties, myself a commander for all practical purposes. Still, whatever the greatness of my illusion, the fact remained that the real commander was there, backing up my self-confidence. . . . Until I was unlucky enough to catch my captain in the act of hasty cork-drawing. The sight, I may say, gave me an awful scare. I was well aware of the morbidly sensitive nature of the man. Fortunately, I managed to draw back unseen, and, taking care to stamp heavily with my sea-boots at the foot of the cabin stairs, I made my second entry. But for this unexpected glimpse, no act of his during the next twenty-four hours could have given me the slightest suspicion that all was not well with his nerve.
