It's story time! The G.C.P.D have a mysterious corpse, a magical box, and a murderer's row of the city's most dangerous villains sitting in a jail cell. Now all they need to figure out is what exactly happened. Fortunately, one suspect is willing to talk. Unfortunately, it's The Joker…

One big puzzle, two winged players -- Killer Moth and Man-Bat must fly together to get a seat at Riddler's table, but from Joker's POV, there's a blood debt to be paid (and not just Riddler's!)

The mystery of “WHO KILLED THE RIDDLER” heats up as Joker, now incarcerated and under interrogation by Commissioner Jim Gordon, retells his version of events, starting with the victim himself on the hunt for an all-powerful weapon. How did the other Gotham villains get involved, and why? What does this weapon do, and why does Riddler want it? Who had skin in the game, and who could stand to lose everything? It’s a whodunit spiraling out of control, retold by the world’s most unreliable narrator. See if you can spot the clues and solve the puzzle!

DIRECTOR’S CUT BONUS BOX: Additional clues for readers: Each issue of Joker Presents: A Puzzlebox includes a BONUS BOX story, giving additional clues and insights to help you stay two steps ahead of Joker!

Joker provides the GCPD with another missing piece of the puzzle involving two faces and two masks: Black Mask has travelled halfway around the world on the hunt for one of the pieces of the MASTER ENGINE, but someone is following him...someone with a gun aimed AT HIS FACE. The mystery deepens with not one but TWO double-crosses in the hunt for who killed the riddler!

"Batman created by Bob Kane with Bill Finger; Superman created by Jerry Siegel and Joe Shuster, by special arrangement with the Jerry Siegel family."

After barely surviving in the jungles of Belize, The Joker flees to Europe! Jim Gordon pursues the madman, but the seeds of doubt begin to sprout...if The Joker didn’t gas Arkham Asylum, who did? And what’s the next move for Vengeance, daughter of Bane? Backup: Punchline’s takeover of Blackgate Penitentiary continues as her most insidious goal becomes clear: find a woman she used to call her friend in her college days and make her pay for her betrayal. On the outside, Harper Row tries to pull her brother, Cullen, back from the brink of Jokerized radicalization!

IT ALL COMES TOGETHER! We flash back to the moment the villains all met to turn over the pieces of the MASTER ENGINE to Riddler...but Riddler isn't there! And just as it's all about to boil over, we get a special suprise guest!

The GCPD is no closer to figuring out who killed the Riddler, now that all of the suspects have confessed to one crime or another, including the murder....everyone except, Joker. Did he actually do it? Is the Riddler actually dead (we've seen his body...)? The last pieces of the puzzle fall into place here.

Très bien-the Joker visits Paris! Gordon must get to Joker ahead of the Sampsons, but has the Clown Prince set an ambush for his pursuers? Plus, Barbara fights for her life after her introduction to the new Talon! Punchline backup: The search for Kelly Ness-Punchline’s former friend who is also in Blackgate Penitentiary-begins.
