I actually wanted to avoid taking two characters from T.S. Eliot, but Macavity was the perfect parallel of Moriarty, the villain of Extraordinary Gentlement, taken from Sherlock Holmes. T.S. Eliot based Macavity off of Moriarty to a point many lines are directly quoted from Doyle.
It'd be fun to try to do a few comic-style stories with these, but unfortunately, I'd have to find new characters to replace Mistoffelees, Macavity, and The Cat, all of whom are copyrighted.
