No: HPFGUIDX 145604 If RAB is Regulus could it be that Mundungus has the locket? If Regulas brought the locket back to #12 Grimmauld Place. Did he take it in his pilfering or maybe stuck in the folds of Kreachers bed. I wonder if Mundungus has it or sold it somewhere and thats why we saw him in Hogsmeade with items from the Black house.
