Before you left Harper, she gave you a piece of paper. Look at the Portrait Letters note in your inventory. The spaces on the page have something to do with the paintings throughout the house. Return to the table in the tool room where you created the battery with oranges. Examine the right side of the table and pick up the rolled canvas. It's the painting of Franklin Thornton from upstairs. Insert Franklin's portrait back into the frame. Use the cleaner-soaked napkin in your inventory on every portrait in Thornton Hall (there are 7). If you find all of them, the Portrait Letters note will be filled in with anagram letters. If you're short on letters, look for Beauregard Thornton's portrait under the stairs and Jackson Thornton's portrait in the second floor hallway. Nancy will tell you when you found all of the letters for the anagrams. Use your hand cursor to rearrange the letters.
