If it's too hot at a family picnic, terrible secrets will come out, crabbily. If it's too hot in England, you find the remains of some lovely secret gardens.
There's a new documentary coming, A Tale of Two Sisters, which, I am promised, is not that weird Japanese horror film I saw where something upsetting happened to teeth. (I think it was teeth? Don't you dare tell me.) Instead, it looks at Elizabeth and Margaret, comparing and contrasting them with Anne and Mary.
