The Perfect Crime quest in Batman Arkham Knight presents one of the most chilling investigations throughout Gotham City. Players must locate six mutilated bodies strung up across various islands while listening for distinct opera music playing in the vicinity. Resolving this mystery requires sharp detective skills and a thorough understanding of the Deep Scan tool embedded within Batman's cowl.

Locating the Mutilated Victims Across Gotham

Two victims are hidden on each of the three main islands of Gotham City, making exploration essential to starting the quest. Players can spot these locations by searching for bright spotlights shone on the victims tied to walls or structures. Listening carefully for classical opera music provides an audio cue that indicates a body is nearby.

Utilizing the Deep Tissue Scanner

Once a body is discovered, Batman must use his cowl's scanner to inspect three distinct anatomical layers. Players need to examine the skin layer, muscle layer, and bone layer to find unique medical anomalies. Identifying these specific traits helps Alfred match the body to missing person files in Gotham's database.

Uncovering the Identity of Professor Pyg

After scanning all six victims, the evidence links the crimes to the mysterious Circus of Strange. Alfred pinpoints the suspect as Lazlo Valentin, better known to comic book fans as Professor Pyg. The investigation directs Batman toward Pyg's secret hideout at the Pretty Dolls Parlor in Ryker Heights.

Confronting Pyg in Pretty Dolls Parlor

Inside the salon, Batman faces Professor Pyg along with his brainwashed minions known as Dollotrons. These enemies do not feel pain, requiring players to utilize environmental takedowns and heavy counters to subdue them. Defeating Pyg allows Batman to rescue the remaining hostages and lock up the killer at GCPD headquarters.
