It is a Puzzle
Severus Snape sat in his dark green, winged-back chair thinking about the "tea" he had attended with the remaining "Black" descendants. He held a clear, lead-crystal brandy snifter in one hand and a thin cheroot in the other. The former was emptying gradually as he contemplated; the latter was unlit and only a prop because he no longer smoked. He found the scent of the cherry tobacco conducive to relaxation and thinking and did not need the nicotine from smoking. That damned snake had made it painful to smoke. "What a drastic way to quit cold turkey!" he thought. He had some scarring, but not nearly what it would have been if he had not been administered the anti-venom so quickly. Then transported to Blackthorn Cottage for healing by none other than the busy-body-know-it-all of Gryffindor and the Malfoy matriarch. Later he had found that they had returned to the battle after summoning a house-elf with healing skills to watch him because neither of the ladies could be missing from the castle grounds for very long without arousing suspicions.
"Harry Potter descendant of Charlus Potter and Dorea Black and Sirius Black's heir, thus the heir to the Noble and Ancient house of Black, had grown into a tolerable young man. His bright green eyes and messy black hair inherited from his parents had become less a reflection of them and more his own. He was a good Auror and equally good godfather to Teddy Lupin."
"Draco Malfoy descendant of Lucius Malfoy and Narcissa Black and his own godson was becoming quite his own man. He had taken his N.E.W.T.s and then gone to business school. Some fancy spell work had been done to obtain a transcript, but he had been admitted to the MBA program straight from Hogwarts and excelled. Malfoy Industries were doing well, thanks to his hard work, ingenuity, and contacts with the muggle entrepreneurs that he had become acquainted with while getting his degree."
"Teddy Lupin descendant of Remus Lupin and Nymphadora Tonks was grandson to Andromeda Black Tonks. The tyke was a Metamorphmagus like his mother had been, but his grandmother had fixed his appearance to include light brown hair and hazel eyes for the venture into the muggle world. He was smart like his father and would probably sort to Ravenclaw if not prompted to something else when he went to Hogwarts."
"Andromeda Black Tonks, sister to Narcissa and the late Bellatrix LeStrange, was ironically the black sheep of the family since she had chosen to marry a muggleborn wizard. Ted Tonks had straddled the line between the muggle and wizard world. With Andromeda as his wife he had remained out of the wizard spotlight though he was well known in the muggle world as a news presenter on the telly. Andromeda was still beautiful with her dark brown hair shot through with wisps of silver hair that made it shine when the light hit it. In her earlier days she had looked more like Bella, but as she aged she was more her own person. Her arresting grey eyes were definitely inherited from the black family."
"Last was Narcissa Black Malfoy, the instigator of the "tea" and the person with more questions than answers. She wanted something that only could be obtained from the group of people who had gathered that afternoon. When she had invited Andromeda to visit with her it was almost like she was orchestrating the outcome in her favor. Narcissa wanted all of the remaining blacks because she needed information. She was playing it close to the vest, but as a Slytherin both he and Draco had more questions as to her motive than the others. What was it that she wanted? How long would she groom the relationships before they realized they had been drawn in to her web like a fly to a spider? This should be entertaining at the least."
"The unknown factors were himself and the godmother to Teddy Lupin, Hermione Granger. Where did they fit into the grand scheme? Were they included, though not Blacks, for their unique expertise? Only time would tell."
Narcissa Malfoy closed the wards on her bedroom suite so that she would be undisturbed by anyone other than the house elves and they knew better than to enter when she closed the wards unless the house was on fire. She went over to her vanity and pulled out the left center drawer, but only an inch. Then she reached under the center portion of the table and felt for the opening. At the bottom was a button flush with the surrounding wood and only those who knew where to look could find it. If she pulled out the drawer too far, it would not unlatch the secret panel. If the drawer was not opened wide enough, it would not only not push, but the drawer would close with a slam pinching fingers in the process. She pressed the button and waited for the nearly silent click of a latch opening. Now she had to be quick and quick she was as she reached for the "privacy skirt" and pressed the lever that had popped out. This opened released a piece of molding in the center top of the mirror and it opened like a drawer. When closed it was invisible because the molding followed the decoration on the trim, but the open drawer was approximately 30 cm long, 5 cm deep and 10 cm tall. It looked like it was only holding a few pieces of jewelry if someone were to find it, but in truth there was a treasure trove below its false bottom. The space was large enough to hide anything Narcissa with its undetectable extension charm. It was also charmed to only respond to her using the accio command.
"Accio Bella's diary," Narcissa commanded. She caught the book mid-air and closed the drawer in one swift movement. When it snapped shut, so did the drawer below.
"October 31, 1980. There is a book in the Black Library in Aunt Walburga's townhouse. I need to retrieve it now that Sirius is in prison and Reggie is dead. The book mentions a treasure that I feel would be a real help to the Dark Lord now that he is in hiding. I may not have time with the Longbottom situation and Barty's loud mouth."
Narcissa mused over the last entry from the book. She had found it when Bellatrix had been arrested for using the crucio to the point that Frank and Alice were blithering. Narcissa, as next of kin had been given all of Bellateix's belongings as she would not need them in Azkaban. She had put them in the guest room where Bella always stayed, but kept the diary. Bella never seemed to miss it and now she was dead as well.
