The Perfect Crime was a Gotham's Most Wanted case file undertaken by Batman on Halloween.


Batman came across a dead body chained to a wall while opera music played nearby. Batman used his deep tissue scanner and learned that the body was left there because the killer saw it as being flawed. Batman found five more victims who were killed by the same person. Batman told Alfred to find the details of the killer, revealed to be Lazlo Valentin, the ringmaster of The Circus of Strange. Alfred tracked Valentin to the Pretty Dolls Parlor. At the Parlor, Valentin called himself Pyg and summoned his lobotomized and tortured Dollotrons to attack Batman. Batman sent the unhinged murderer and his victims to jail.


  • This mission was one of the reasons why Arkham Knight got an M-rating due to how Pyg tortures his victims.
