A month later, however, the mood had definitely shifted. The bleak weather of January in London suited Hermione’s disposition just fine. Every day she woke to weak sunlight in a grey, dreary sky, spent the majority of her waking hours chugging coffee and poring over old records in the Ministry archives, and returned home well after the lacklustre sunshine had given way to the slightly darker gloom that signified dusk. Even her twice-weekly duelling sessions offered little improvement over the archives, as the hopefulness of the new year settled into frustration for everyone over their lack of progress. They were all on edge, and Hermione felt the pressure more than ever to come up with answers. She'd even resorted to taking one of a precious few phials of  Felix Felicis  she'd brewed after the Battle of Hogwarts, which had resulted in a lovely few hours of not having to wait in lines or deal with her more obnoxious coworkers, but no new leads.
