Poison the drink of Advisor Lavella!
You are discreet and work efficiently. This is good. I need someone just like you. As you know, I am an advisor to a nobleman of high birth. My lord unfortunately tends to ignore my words because he puts his trust in his advisor Lavella. She is soft and tender-hearted and does not understand that sympathy and gentleness are bad advice when one is as powerful as my master. The time has come to remove her.
This is where you come in. My alchemist has concocted a potent poison from shadow herbs. I know that Lavella likes a to have a nightcap right before going to bed. Enter her house and put a few drops of this poison into her drink... Hurry up. I will reward you most handsomely.
