If Mr. Black were to be removed from his family’s page, and put instead in the roster of Muggle-borns, then any magic would set off an alarm, but it would be name-less, since your name would not have been recorded in the new pages. Of course, you must still deal with the location problem, but I have come across a counter potion for that as well." He dipped down, then reappeared with a corked glass bottle. Midnight blue potion sat inside, gurgling faintly. "A swig once a day, though its effectiveness increases after a week. It builds a resistance to location determination. After that, you need only drink it once a week."
