Skyrim:Stranger's Final Instructions (pickpocket)

You're good. You picked her pockets clean and made the switch.

Now you'll need to put those skills to the test and more. In Silverdrift Lair is a tomb that houses an ancient Nord clan. Near a large chest is a corpse with a lantern, its candle still burning. It holds a key.

When you have the key, open the chest and you'll find a sword that can raise the dead.

When you find it, bring it to the grave of the Gray Fox in Riften. It's a small, unmarked headstone on the east side of the cemetery. Complete the task, and maybe you'll even get to meet him.
