Silver's Debt

Silver's Debt is a minor Fallout 3 quest. If you tell Moriarty you don't have 100 caps to buy information on your father, he will give you a cap raising task. He wants you to find a woman called Silver and get his money back. You can find Silver at the north-west of Megaton, inside a ranch house.

You reward yourself by taking any actions you want. But best is, convincing Silver, by doing this, she'll give you 400 caps (bad karma), a nice start for the game. It is possible to receive 500 caps if you get 400 and then kill her.

It is actually possible to get the money from her right after you exit the Vault, just go left from the vault and go to her Ranch. she will ask if you are coming for the money and after some dialog, you will be given the choice of getting the money and telling Moriarty that she has in fact run away. If you choose to tell Moriarty that she is dead she will still be around, and the quest will be be ungainable, since you do in fact already have some money to pay him with.
