The trio are captured and taken to Malfoy Manor. Bellatrix tortures Hermione, believing they stole Gryffindor's sword from her vault at Gringotts. With the help of Dobby the house-elf, they escape to Bill and Fleur's house along with fellow prisoners, including the goblin Griphook. During the escape, Dobby is killed by Bellatrix. Harry has a vision of Voldemort stealing the Elder Wand from Dumbledore's tomb. The trio decide to break into Bellatrix's vault, believing another Horcrux to be there. With Griphook's help, they break in, retrieve Hufflepuff's cup, and escape, but Griphook steals Gryffindor's sword in the process. Harry has a vision of Voldemort being informed of the heist. Voldemort decides to check on his Horcruxes, revealing the remaining ones: Nagini, and one at Hogwarts.
