Marcone/Dresden So, Marcone has listening and watching devices set in Harry's flat (it's magical devices, okay) and checks what his not-quite-ally but not-quite-enemy does 24/7. And it's kind of addicting. He knows Harry's sleeping habits, if he sings in the shower, what he does when he's not destroying buildings/saving Chicago/killing things. Somehow it progresses from possible enemy monitoring to stalkerish obsession. And then Harry finds out.
