Detailed walkthrough

After taking one (or both) of Decker's quests (Dispose of Jain and/or Dispose of merchant), the Vault Dweller can choose to report Decker's crimes to the Hub police. Sheriff Justin Greene will offer them this unmarked quest if a Charisma check is passed, promising 300 caps up front, and 1000 caps upon completion of the quest.

The Vault Dweller's party (now including Sheriff Greene and Deputy Fry) fast travels to the basement of the Maltese Falcon to confront Decker and his guards.



  • After killing Decker, some (or all) of the remaining guards may surrender. They can be found later in the basement of the Falcon. If engaged in combat again, they will most likely repeat "I surrender!" once again.
  • If the Vault Dweller talks to Beth after completing this mission and mentions that they were the one who killed Decker, she will give them six stimpaks.
  • If the Vault Dweller has an Intelligence of one, taking this quest becomes impossible. An Intelligence of at least level two requires the use of Mentats.
  • If the Vault Dweller has killed Lorenzo, (without previously having killed Killian /- Gizmo) he will be unable to acquire either of Decker's quests, making this quest unavailable.
  • If Sheriff Greene is killed during the combat phase of this quest he will be categorically unable to recompense the Vault Dweller, or express how a "debt of gratitude" is owed; consequently the remaining (1000) caps can be retrieved from Deputy Kenny.
