After their flight from Malfoy Manor, our favorite trio learns that the hairs Hermione found were not from Bellatrix Lestrange, but probably from a dark-haired cat. Harry feels compelled to look for a way to get Bellatrix's hairs, in order to get into her vault in Gringotts. It is extremely important for Harry to destroy the Horcrux in her vault, even if it means going to a Death Eater party in disguise... In other words, read how Harry moves through a nest full of vipers, only to get entangled in the most deadly of them all. This is a 'one shot'. Pairing: Harry Potter x Tom Riddle | Voldemort. If there is demand I will continue with this story. Mature themes, smut, etc.
