The Shadow-Line

The Shadow-Line is based upon events and experiences from twenty-seven years earlier to which Conrad returned obsessively in his fiction. A young sea captain's first command brings with it a succession of crises: his sea is becalmed, the crew laid low by fever, and his deranged first mate is convinced that the ship is haunted by the malignant spirit of a previous captain.
The novella is notable for its dual narrative structure.
