it's a good chance the locket Harry saw in the cabinet in Grimauld Place was the locket. In Harry Potter and the Order of the Phoenix, when they are cleaning out the parlor in Grimauld Place, a locket is mentioned, but only briefly. If it's anywhere, you'd suspect it's someplace in Grimauld Place, where we assume Regulus lived with his parents. So, where is the real locket now? Regulus' note says he intends to destroy it as soon as he can, but we don't know for sure that he did. Or this 2006 Beyond Hogwarts article, which guesses not only at RAB's identity but almost every detail of how the locket plot would eventually go down: I think that Harry will again find help in a person that he was not expecting. is through either Sirius’ house or Kreacher both of which he has conveniently inherited. I think it is likely that Harry will come to figure out who the mysterious R. It takes a lot of guts to go against Voldemort, and I have a feeling Regulus knew he could never hide from Voldemort, and if he was going to die, he did not want to do it cowardly but was going to try to do something that would be devastating to Voldemort. Regulus probably did get scared, but unlike Draco, he refused to do what Voldemort was asking him to do and actually tried to help the future vanquisher destroy Voldemort. I have a feeling that Regulus found himself in a situation similar to what Draco Malfoy got himself into in HBP. I think Regulus probably had more courage than Sirius gave him credit for. has to follow, I will state who I believe the person is: Regulus Black, Sirius’ younger brother. Now that I have laid out the criteria I believe our mysterious R. Take a look, for example, at this Mugglenet Article published only four days after the release of the HBP, which pretty prescient both in the general and specific details of RAB's identity: With a fanbase as big as Harry Potter's is, there's never a complete consensus on anything, of course - but pretty much from the beginning "RAB = Regulus Black" was the frontrunner theory, with only small pockets of fans speculating anything else.
