The Muggle book needs to go back to the library before someone notices it, so he picks it up and leaves his study. The manor is dark at night, and mostly still, but there are slitherings and whisperings that didn’t exist before the occupation of the Dark Lord, and Draco’s stomach turns. He wonders if he’ll be able to live in the Manor in the future, or if it will always be tainted for him now – not that it matters, because the future may never happen, and if it does, he can deal with the Manor then. Everything except defeating Voldemort has to be put off until then.
