The Joker Presents: A Puzzlebox # 1 2021 NM-

The Joker Presents: A Puzzlebox # 1 2021 s the first issue of a seven-part murder mystery miniseries published by DC Comics. It features The Joker as an unreliable narrator telling a story to the G.C.P.D. to help them solve a high-profile crime. 

• The Murder Mystery: Commissioner Jim Gordon and the G.C.P.D. are investigating a mysterious corpse—revealed to be The Riddler—found alongside a magical box.
• The Interrogation: The story is framed around an interrogation at Gotham Central. While several of Gotham’s deadliest villains are in custody, only The Joker is willing to talk, spinning a series of potentially fabricated tales to lead or mislead the police.
• Flashback Narratives: The Joker recounts seemingly unconnected stories about fellow inmates—including Harley Quinn, Catwoman, and Black Mask—as they hunted for an all-powerful weapon called the Master Engine.
• The "Puzzle" Element: Originally released as a digital-first series, each issue included a "Director's Cut Bonus Box" with additional clues intended to help readers solve the puzzle ahead of the characters. 
• Creative Team: Written by Matthew Rosenberg with main art by Jesús Merino and Joshua Hixon.
• Release Dates: Digital chapters began on June 7, 2021, followed by the print release on August 3, 2021.
• Continuity: The series takes place outside of the main DC continuity, allowing for unique interactions and status quos (e.g., Bane is still alive while Riddler is dead). 

• Protagonists: Commissioner Jim Gordon, Detective Harvey Bullock, and Batman.
• Villains: The Joker, Harley Quinn, The Riddler (deceased), Bane, Black Mask, Catwoman, and Poison Ivy.
