In order to unlock this, you’ll need to question every suspect that is potentially involved with the murder, completing a set of 4 quests, which are:
- The Productivity Queen – Investigating The Prophet
- The Prince of Tossball – Investigating Bertie
- The Man Who Chafed – Investigating Spencer Woolrich
- Lord of Blight – Investigating Sedrick
The Productivity Queen is a missable quest (the others are not). Make sure you get it ASAP: Go down to the lobby of the hotel and speak with Bellhop Norville. He can be found standing in front of the elevators wearing a red hat. Question him about the murder and he will eventually mention The Prophet. You’ll then be given the quest.
IMPORTANT: During the resolution of these quests, make sure not to accuse any of the suspects to Ludovico until all 4 quests are completed.
