The Joker Presents: a Puzzlebox

"Sixteen suspects in jail. One murder. No clues. And the only one who's talking always wears a smile... You can call the Joker a lot of things - psychopathic, murderous, disturbed, obsessed, anarchic, maybe even genuinely funny. But one thing no one would call him, regardless of what side of the law they might fall on, is dependable. The Joker will double cross his own partners on a whim, let alone anyone trying to stop him. Yet when it comes to solving one of the strangest, most perplexing mysteries to ever hit Gotham, the Joker's word is about all that the Gotham City Police Department has. A mystery with the most unreliable narrator in the DC Universe, this seven-issue miniseries finds Commissioner Gordon and the rest of the GCPD with a headline-grabbing crime on their hands, a suspect list that includes just about every villain in Gotham, and only the Clown Prince of Crime's testimony as a lead. But how much of what the Joker says can they believe? Was he behind the crime, or just a witness? Is that red stain on his shirt just a little strawberry jelly like he claims? Why isn't anyone else willing to talk? And most importantly, who killed the Riddler?" -- page 4 of cover.
