Re: Level Nine: Department of Mysteries
After she is done on Level Eleven and the Dark Lord sends her off on the next step of things, Bellatrix takes Alex with her to the home of Barnabus Cuffe, editor-in-chief of the Daily Prophet. There he can watch while she tortures him into agreeing to only run stories approved by Minister Thicknesse and his new cabinet, giving the DEs de facto control of the Daily Prophet.
It doesn't take much torturing to get Cuffe to agree, when it comes down to it. He only puts up a facade of a fight, then agrees at the first bit of pain.
