It litterally says:
''Here is the agreed upon amount. I expect you to faithfully carry out my request to teach a lesson to the thief Ylva (my character her name). You need not kill her, but I have no qualms about it if you seem it necessary.

--Forsworn Briarheart''

...So i pickpocketed the heart of a forsworn, i saw him die. Then how did he write this?

Twin brother?

I got a contract on me and didn't even steal anything but was caught picking a couple locks but still I took nothing. I'm innocent.

Radiant story at its very best, working as it's supposed to!

At the market stalls in Windhelm, the Elven woman selling armors, weapons, potions, just about any and everything, stands behind a very crowded and cluttered booth. Recently, I was trying to talk to her, and wound up stealing something from her stand instead. No reaction.

A bit later, three thugs jumped me, killed 'em, and they had a note from her. I gathered up their gear, headed back to Windhelm, and sold it all to her, and she still had no reaction. But, after that, I go around to the back of the stall so as to avoid any further misunderstandings (unless I'm short on cash, and just want to sell her the thugs equipment, then I steal something and wait....)

you should wait til she closes and follow her home then murder her in her sleep

don't worry about it i was actually atacked by some tugs that where contracted by someone i haven't even meat acusing me of stealing in a city i haven't even been into yet at the time so ye radiant AI at it's best, just like the contracts on our head by the DB before you join them...

I got a letter of inheritance from 'Apprentice Necromancer' once.

haha You're not innocent. Picking locks is breaking and entering. At least in the real world...
