Summary
This is an essay in which I'm trying to make sense of events in book 2. What did Lucius know about the diary and why did he plant it on Ginny? What happened in Hogwarts in 1943? Why did nobody ever suspect a Basilisk? Why did nobody ask Myrtle how she died? Who else was harmed, and how? Who hid the entrance behind a sink? How did the Basilisk manage to get around in pipes?
