  • The Master of Disguise case will now begin.
  • Head into the Casebook once again and this time pin the Sketching a Thief evidence


  • Now leave the Police Station and head to Knights Rd.
  • Here there will be a store named Mrs. Nini’s Atelier
  • After speaking with Mrs. Nini head into the back room and search for a painting of a man wearing a black top hat and a white suit
  • Interact with this painting and John will suggest we dress up as him
  • On the shelves behind you there will be a box full of various glasses and another one with several makeup essentials in, take them both.
  • On the next shelf there will be several black suits, select and take this one too. As well as the hats that can be found next to the black suits
  • With all four pieces of clothing, head into the Wardrobe menu
  • Select the following pieces of clothing to wear; White Suit, Top Hat, Long Sideburns, and Old Man Make-up
  • Now return to Mrs. Nini and she will think we are Uncle Giovanni

  • Regardless if you needed the trophy achievement or not we need to head to Mrs. Nini’s Atelier anyway for the story
  • However, instead of dressing up as Uncle Giovanni we need to equip the Ugly Beige Suit, Bowler Hat, Square Glasses, Pencil Moustache, and Fake Bruises
  • When you are done playing dress up, go ahead and speak to Mrs. Nini. We will now get the location of the Clothing Trader
  • NOTE: If you purchased the Digital Deluxe Edition, you can now equip the extra costumes. Costumes such as the Victorian Vampire and Consulting Detective outfits
  • Return to the Police Station and speak with Stark
  • This will conclude the Master of Disguise Case.
