From several different sources including Apartment Therapy and Croatian Times, but the Daily Express seems to have the most complete story, on the discovery of a martial arts novel written on the walls of an abandoned home.

"The story is entirely written in Chinese lettering and also includes illustrations.
Unfortunately however, no one knows who wrote the book, or why they did it.
But now the story has become a massive online hit after one fan uploaded photographs of the novel on the internet.
One excerpt reads: 'I was 17… I have reactions like lightning, hearing like a bat, my vision is like a hawk, and I am as strong as a general.'"

Thanks to Hal Kelly for pointing this out to me.
