The Captain of the Polestar, and Other Tales

This collection of short stories was first published in 1894.

Essentially, the Captain of the fishing boat, Polestar, goes insane while his boat is temporarily ice-bound. Fishing hasn't been good, so they thought they might have better luck further north, but they stayed a bit too long. The whole crew was nervous, jittery, concerned about potentially dying for lack of food, water, and heat, if the weather didn't warm enough to allow the ice to break up a bit. One by one they started seeing things, as the captain sank deeper and deeper into himself. In the end, the boat gets free and heads back in to its home base, but it is anything but a "happily ever after" ending.
