During his 30s, which you must remember was the 1960s he continued working in the shop called Borgin and Burkes, a place I am sure you know, in Knockturn Alley and close to where I currently reside. It is during this time that his “rise” began, with the murder of various people including Hepzibah Smith. She was the owner and descendant of Hufflepuff and if is through her murder that he was able to create the Horcrux of the Hufflepuff cup. It is during this time that he started to push the boundaries of magic.
