But when she finds the key but couldn't find the door, she becomes disappointed. So when she does, she is ecstatic. Then, she finds her crippled cousin and starts to take him to the garden.
I didn't really like this book. I couldn't really get into it and I couldn't understand a lot of the talking, because it was a long time ago. Also, since it took place in England, they spoke Yorkshire, a version of English slightly different from how we talk today.
