When exiting Whiterun one day my character was met by some thugs who wanted to "teach" me a "lesson." After looting them I found a note from the NPC that put the hit on me. It was from Arcadia's Cauldron in Whiterun.
... so I went back to the NPC with the note in hand expecting to be able to confront her about it. There was no such dialogue option, and she was cheerful / eager to sell me something. Is there no way to confront the people that put a bounty on my head?!
I thought about putting an axe in her back but it would be meaningless. I want the NPC to know that I figured out her plan.
