This quest is acquired from Hanekin Hare during the quest 'Hare Hunt'. It is the continuation of the quest line once you side with Hanekin. The first thing you should do is go to the mine shaft (marked on the map) where Hanekin will meet you. If you arrive soon after speaking with him in the woods, wait one hour using the time dial for him to appear.
Speak with Hanekin Hare and exhaust all the dialogue options. He will ask you to go back to the huntsman’s lodge to abduct Margaret. You should begin by removing any items that have high noise ratings to reduce the chances of being caught.
The guard is present at all times, both during the day and throughout the night. Whether by day or night, you will find Margaret in the front room of the lodge, as marked on the map. Take note of the patrolling guard and the route of Nicholas before you make your way into the lodge. Once there, crouch and knock out Margaret. You can then pick her up and carry her through the woods to the mine gallery, where Henekin is waiting.
When you arrive at the mine gallery Hanekin Hare will speak to you. The next step involves taking a document to Nicholas. Return to the Lodge and present him with the document, informing him that he should leave Talmberg immediately after signing it. With the document signed, return to Hanekin. After speaking with him, a cut scene will initiate in which Hanekin is cleared of his previous charges.
You will have the option to become the new Master Huntsman of Talmberg. Accepting the office will provide you with the quest 'Henry the Master Huntsman'. You will gain possession of the hunting lodge and you will be required to bring game meat to the Talmberg Chamberlain.
