Can't recall the name of the book that I read being a kid about a decade ago. It's written by a renowned English author who grew up as a blue-collar labor worker in 19th or 20th century England. As a matter of fact, he materialized many of his experiences in another book, which talks about a young poor hard-working man falling in love with a beautiful lady from aristocracy and working his way up by educating himself and becoming literate.
The short story or novel in question is about a weakened man, who was betrayed by his companion on a trip. He had no food or water and was exhausted to death. Soon after, he encountered an injured half-dead wolf and had to wrestle with him. The story emphasizes the physical as well as the psychological struggle, turmoil, and pain that the man endured. After winning the battle, he was rescued by a ship crew and was well fed and cared for.
It's a fascinating story by an extremely well known author, but I just can't remember either his name or the name of his book! Would be very glad if you could help me out.
