She wanted Niellen even though she’d known all along about him being a werewolf, so she brought Hannah during a time when Niellen was to transform into a werewolf. However, the incident was put in motion because Hannah’s sister was jealous of her.

You’ll find out that Niellen is the werewolf and that he was the one who killed her wife, Hannah.

Use cat potion to see in the dark and defeat the werewolf.

Find a way to get underneath the cabin.

Enter the cabin to investigate and find other clues.

You will come across shredded clothing without a blood.Follow its scent leading you deep into the woods. Look around some more until you find a tuft of fur.

As you arrive, use your Witcher Sense to find clues.They were last seen headed into the forest. Some children saw Hannah leave with a woman.Ask the neighbors about Niellen’s wife.

This is a contract to find a missing woman. At this point you'll want to make sure there are no wolves left to annoy you, and focus all of your energy into all-out aggression in order to outweigh the werewolf's regeneration with high damage output.This quest is unlocked when you visit the Crows Perch Boards. Like other werewolves, this particular monster gains the ability to regenerate HP after you get his health bar down to half.

Although they boast an offensive fighting style, their health is low, and they can be incapacitated in just a few hits - leaving them alone to focus on the werewolf is dangerous and unnecessary in the long run, especially when you consider its second phase. The werewolf is accompanied by three ordinary wolves, all of whom should be dispatched immediately. After a short amount of time elapses, the werewolf will appear. Once you arrive here, you'll be given a prompt to meditate, as Geralt often does while he waits for monsters to return to their lairs. F ollowing the trail from here brings you to a shack, which in turn leads to the werewolf's lair. If you continue along the questline after having ignored Margrit's pleas, you'll (a bit comically quickly) come across Hanna's corpse, which Geralt determines is clearly the work of a werewolf.
