The Perfect Crime is another Most Wanted mission that you can start right after taking Poison Ivy to the GCPD in Batman: Arkham Knight. Speak with Office Aaron Cash to learn about a murdered victim who was found on Merchant Bridge. Head over there and use your Deep Tissue Scanner to analyze the body for clues.
There are a total of six victims (two on each island) that you must find and investigate in any order. Each corpse requires three scans, one in each layer: skin, muscle, and bone. You can use “Aim Gadget” and “Crouch” to switch between layers. The location of the killer will be revealed once you have analyzed all six bodies.
Except for the first victim which Aaron Cash marks on your map, the remaining five bodies have to be found on your own. They can be a bit difficult to spot due to their blending environments. If you hear opera music playing in the background, it means there is a Perfect Crime location nearby. Follow the music to the body which will always be put on display under a shining spotlight.

Confront the killer – Professor Pyg
Once you have discovered all six Perfect Crime victims, the location of the killer will be revealed in Batman: Arkham Knight. Head over to the Pretty Dolls Parlor in Ryker Heights. The shop will be on the underground level.
Head inside the parlor and proceed through the backdoor to listen to the familiar opera music. Go down the steps and you will find Professor Pyg in a surgery room.
A short cutscene follows and after that, you are thrown into combat with Professor Pyg’s pain-resistant and stubborn “Dollotrons”. It is essential to be patient here since they require very lengthy Beatdowns or Environmental Takedowns to be subdued.
After you have successfully defeated the initial patients, Professor Pyg jumps into the fight himself, albeit from a distance where he periodically throws cleavers at you. Counter these cleavers to stun him and use that time to subdue the remaining Dollotrons.
Knock out Professor Pyg using an Environmental Takedown after defeating all of his patients. Then head to the panel to free his hostages who you just saved from becoming more Perfect Crime victims. Place the Professor in your Batmobile, and take him back to GCPD to be locked for good.
