Heidi is too good to be true, but it isn't her fault. All in all, it was harmless. It's obvious that Frances Hodgson Burnett read Heidi before writing The Secret Garden and plagiarized extensively. The garden replaced the mansion. The crippled boy, Colin, replaced the crippled girl, Klara. The mystical force of nature replaced the "Good Lord." There are other similarities: Peter the goatherd/Dickon, the boy from the moor; Ben, the gardener/ the Grandfather; the robin/the goats; both cripples have fathers who are always away on business. I could go on but you probably get the idea.
