To find all of the Sokolov paintings, look in the areas described below. Some areas contain more than one painting. If you're having trouble, you can use the Heart to make the search a bit easier.

High Overseer Campbell - Gain entry to the mansion's basement, which you can enter by pressing a hidden button that is located on the wall just across from the kennel's entrance. Once inside the basement, explore to find the painting.

House Of Pleasure - At the Golden Cat, question the art dealer to learn the combination for his safe. You can find three paintings in the apartment: one in the safe, one in a guarded room on the second floor, and one in the bedroom located on the third floor.

The Royal Physician - Tend to the guards on the first floor in Sokolov's house, then take the painting they were protecting.

Lady Boyle's Last Party - At the point when you are looking for a Boyle sister, do a bit of looking around. Near where you find the target of your search, you will also find a painting. A second painting, meanwhile, is located on the mansion's second floor. Look for it near center of the show room.

Return To The Tower - Look for a room with a conspicuous fireplace, on the second floor inside the tower. The painting is hanging above that fireplace, in plain sight.

The Flooded District - A ruined building with three floors is located in the Waterfront region. Ascend to the third floor and use the Blink spell to snag the painting before you head for the refinery. After you clear out the Assassins' Headquarters building, look for a chain as you are leaving.
You can climb along it to find a platform on your descent. There you will find a second painting. Then seek out a third painting in the sewers, near the Old Port District Outskirts. It is upstairs from the area where you deal with Granny Rags.
