One of the notes pegged to the Notice Boards says Neillen’s wife disappeared. Agree to go after her and visit Blackbough. If Geralt didn’t go there yet, use the Hangman’s Alley fast travel point and then head east to Blackbough.
Interact with Neillen and then speak to two of his neighbors. Follow the waypoint to the forest and use Witcher Senses to find Hanna’s corpse, as well as some wolves. Kill these animals and Hanna’s sister will appear. Agree with her and Geralt receives 55 Crowns. Hold out for a bit and you stand to gain 65 Crowns.
Should you choose to continue, activate Witcher Senses and check out the wolf corpse marked in red. Examine the nearby claw marks and Geralt will discover that a werewolf is responsible. Time to go to its lair.
Begin by checking for blood. Follow it and Geralt will come upon a tree. Inspect the tree and then discover some fur. You will now pick up the werewolf’s scent, leading to some clothing.
Check out these clothes and follow the path until you see a hut. Go into the hut and examine the bedroom to find notes. Exit the hut and go around back to discover some blood and a door. Use Aard Sign magic to open it and you’ll not only find the werewolf, but also some wolves keeping him company.
Start off by killing the wolves and then battle the werewolf. Hannah’s sister shows up just before you decide the werewolf’s fate. If you let him live he responds by killing her. Whatever you choose, take down the werewolf, examine his body and collect Niellen’s Key. This ends the quest, and you can go back into the hut and take items from the chest in the bedroom.
