In the 1920s Salazar Slytherin's locket was sold at Borgin and Burkes to Caractacus Burke by Merope Gaunt for ten Galleons. Burke later sold the locket to Hepzibah Smith, who paided an "arm and a leg for it". After graduating from Hogwarts, Tom Riddle worked as a shop assistant at Borgin and Burkes. His employers were surprised when he resigned his post and disappeared after the murder of Hepzibah Smith. After Riddle murdered Hepzibah he also stole Slytherin's locket from her, as well as Hufflepuff's cup.
Harry Potter first entered Knockturn Alley in 1992 when using floo powder at the Weasleys. He ended up inside Borgin and Burkes when he didn't say "Diagon Alley" clearly enough when trying to travel there by Floo powder from the Burrow. He ran into Rubeus Hagrid outside the shop. Hagrid, who was getting Flesh-Eating Slug Repellent in Knockturn Alley, told Harry that he shouldn't be hanging around in such a "dodgy place".
Harry's next visit to the alley was in 1996, when he, Ron Weasley, and Hermione Granger followed Draco Malfoy, Harry suspected him of being a Death Eater. Draco let several Death Eaters into Hogwarts through a Vanishing Cabinet in Borgin and Burkes at the end of the 1996-1997 school year.
From the shops, one can purchase many types of dark objects, which include poisonous candles, shrunken heads, giant spiders, human-looking fingernails and toenails, and Flesh-Eating Slug Repellent. Because of its contents, Arthur and Molly Weasley prohibited their children from entering Knockturn Alley.

AccessAs with Diagon Alley, Knockturn Alley is not directly accessible from the Muggle world. The Leaky Cauldron pub provides one access (via Diagon Alley), while Apparition and Floo powder are other access options. There may be other entrances. In addition, as noted above, a vanishing cabinet located within one of the shops provided direct access to Hogwarts.
The name "Knockturn Alley" is a play on "nocturnally", just as "Diagon Alley" is a play on "diagonally". "Nocturnally" has to do with the night and darkness, hinting at its dark nature.

Behind the scenes
- The Whispering Wizard may have been an inhabitant of Knockturn Alley.
- The 2-disc DVD edition of the film adaptation of Harry Potter and the Chamber of Secrets includes an interactive tour of Diagon Alley, which includes one of the entrances to Knockturn Alley (in the early films depicted as being directly to the right and behind the Leaky Cauldron access), although the tour does not progress into the alley itself.
- In the movie adaptation of Harry Potter and the Prisoner of Azkaban, the Shrunken Head in the Knight Bus announces "Next stop, Knockturn Alley!" after the Knight Bus has dropped off Harry at the Leaky Cauldron. This suggests that either there is an entrance to Knockturn Alley that does not lead through the Leaky Cauldron and Diagon Alley, or that the Knight Bus can actually jump into Knockturn Alley, to a bus stop there. This is not seen (or possible) according to J.K. Rowling's book canon.
