However, even if you agreed to lie to Niellen, as long as you don't go back to talk to him, the clues still linger and Geralt can still investigate despite telling Margrit otherwise. If you accept, you'll earn 80 and 55, the search field disappears, and the quest can be finished by talking to Niellen back in Blackbough. You can either accept the bribe or keep searching.

After they're dealt with, Margrit appears and attempts to bribe Geralt to lie to Niellen, saying she doesn't want to lose him and he deserves better than this. Eventually Geralt finds a pack of wolves gathered around a corpse.

Now head out to the marker in the woods to find more clues about Hanna's whereabouts. In addition, the latter's children also give Geralt a bit more information about the morning Hanna disappeared. There are a couple people Geralt can talk to: the butcher's wife and the blacksmith. Talk to him and agree to look for his wife and the two will give you several people to talk to and a location to check out. In Blackbough you'll find him standing in front of a hut talking to his sister-in-law, Margrit. You just need to obtain one to read to then find Niellen in Blackbough. This quest can be picked up from several Velen notice boards, including from Mulbrydale, Midcopse, Inn at the Crossroads, and Crow's Perch.
