An Idea

I would like to write a story, novel, or something about finding secret art. I imagine, for example, that I am looking at an estate. I go into the basement and I find something amazing. Apparently, the man who had owned this home for years had a secret obsession. Each month, every month, for years he had made his own comic book. Writing and illustrating it then carefully hiding it away. I can imagine looking through various issues randomly, seeing events at that time current incorporated into a huge private fantasy. Trying to figure out just why did he do this. Why did he hide it? I think these would be fascinating questions to tackle.
