Narcissa didn't have much time, so she looked around and had to improvise a plan. Locking the doors with colloportus, she ripped a part of her dress off and tossed it over the partial remains of an Inferi that was hacked to pieces so unrecognizable that the House-Elves left it behind. Glancing around, she found other dead parts that appeared to be female and picked them up, and slightly concerned at how little it seemed to repulse her now, tossed the arm and head atop of it.
