 * 4) Kill Daren Hightower.

Detailed walkthrough
To receive this quest the Vault Dweller must first speak to Lorenzo at the Friendly Lending Company and ask him about Decker. Lorenzo will tell the Vault Dweller who to go to for work. The Vault Dweller then ought to tell Kane in the Maltese Falcon that they are looking for a job, and mention Lorenzo's referral.

After accepting the quest the Vault Dweller can collect their $500 down-payment from Kane. Then they need to go to the southwest exit grid in Downtown of the Hub. This will take them to the Heights. The Hightowers live in the building in the middle of the section. The Vault Dweller should talk to the guard outside the door, and mention that they're running late for an appointment to get into the mansion.

Then it's just a matter of walking into the merchant's bedroom and opening fire. Both Daren and his wife need to die. Talking to Mr. Hightower will result in the Vault Dweller being kicked out, so just shooting the couple is preferable. In response, all 5 of the guards will come running, armed moderately well. Three have 10mm SMGs, one has a Desert Eagle, while Leon has a 14mm pistol. Decker demands eliminating any witnesses, so they need to go too.

Another way to get the quest done is to come at night, after 7PM, and promising to go away when the guard that hassles the Vault Dweller. Instead of leaving, the Vault Dweller should go round the house clockwise, and until just around the corner so that the guard in front of the door sees them (leep facing away until guard turns). When the guard passes around the corner, the Vault Dweller should run back to the door, open it, then close it once their companions are also inside, but before the guard returns. The Vault Dweller can now kill Hightower and his wife without the guards minding, as long as the Vault Dweller ends combat mode before they go, and they don't enter the guards' field of view (sight) on their way to the exit grid. There isn't any particular advantage for doing so, except if they just want to avoid bloodshed, or are weak in combat.

The Vault Dweller can then head right on back to the Maltese Falcon and speak with Kane to get your reward. Hub Cops will not turn hostile.

Take down Decker
After getting this quest from Decker, the player can choose not to do it at any time and rat him out to the Hub Cops, Sheriff Justin Greene specifically. He'll request the player's help in raiding the Maltese Falcon and stamping out the Underground. The Vault Dweller can even do this after completing the quest and receiving their reward, as long as he succeeds a Charisma/Speech check.
