Some authors of books create their own cipher to improve on the story. Sir Arthur Canon Doyle does do this in his Sherlock Holmes stories:
Mr. Hilton Cubitt of Ridling Thorpe Manor in Norfolk visits Sherlock Holmes and gives him a piece of paper with this mysterious sequence of stick figures.
The little dancing figures are a main part of the mystery, which seem to be driving his young wife Elsie Patrick to distraction. He married her about one year ago, and until recently, everything was well. She is American, and before the wedding, she asked her husband-to-be to promise her never to ask about her past, as she had had some "very disagreeable associations" in her life, although she said that there was nothing that she was personally ashamed of. Mr. Cubitt swore the promise and, being an honourable English gentleman, insists on living by it, which is one of the things causing difficulty at Ridling Thorpe Manor.
You can read the rest of the story on your own, if you are still not sick after all these puzzles!
