Received this achievement by accident. I had Blink II and Agility II enabled.
During the High Overseer Campbell level, you are confronted with the Wall of Light in order to access the area beyond. Follow the tubes and ductwork on the side of the Art Dealer's house until you are facing the Wall of Light. There is a large sign across from you on the right side of the Wall of Light. Blink to the top right corner of the sign where it meets the corner of the roof. Then Blink or jump onto the roof.
Cross over the roof while in stealth mode. You will be directly above a watchtower. Blink onto the watchtower and remove the Whale Oil tank. The guards will immediately be alarmed. Blink onto the roof across from you - it's wide and separates the two streets. Hug the back brick wall until the guards lose interest, only takes a few seconds, and the achievement will pop.
Once the guards stop their pursuit, you can jump down and access the transition door to the Golden Cat House.
Note: Do not rewire the control panel as the system will then kill all the guards in the area and you will not get the achievement.
