Query: Ghost of Opalina film

I've been trying to learn who currently holds the copyright to this40+ year old children's story for years. I feel Disney should optionit for an animated/live action film but without the copyright holderbeing contacted, no script can legally be drawn up.It's a wonderful story and one that's remained a favorite among thefew readers who've found it.
