The doll

The doll is a quest in the Witcher module Damn those Swamps!.

Walkthrough
After completing 'Kill the drowners', a Girl will appear in the village. To begin this quest speak to the Girl, and she will tell you that she lost her doll near the Clay Pits, and will ask you to retrieve it. If you refuse to help her, the quest will simply not progress until you do. Head to the Clay Pits southwest of the village to look around, then wait for Geralt to comment, and return to the Girl empty-handed as there is nothing there to be found. The Girl will persist that the doll is there and urge you to go back and look again. Again, there is an option to refuse, if you want to put the quest on hold.

Head to the Clay Pits again to discover a drowner. However, it turns out to be friendly, as attacking it will initiate a dialogue in which you can either express your bewilderment, or attack the drowner. If you leave the drowner be, it will hand you the doll. If you kill the drowner, its corpse turns into that of a woman, and you must loot the doll from the body (along with a red shawl if you so desire).

Return to the Girl to give the doll back to her. However, the Girl pretends that she doesn't know anything about a doll, and remarks that she shouldn't talk to strangers, before retreating to her house.

The search
A little girl asked me to find her doll. Something scared her and as she was running away she dropped her toy. I have to find a lost doll.

There is no doll.
I went to the place pointed by the girl, but there was no doll there. I couldn't find the doll.

Return
Guess I'm getting old. As the girl requested, I'll go look for her doll again. I'm going to look for the doll one more time.

Merciful / Killed
The drowner is left alone: I've came across a drowner who could speak and he claimed he's not a drowner. I don't understand what's going on. I have the doll. (50 XP) or

The drowner is killed: I've came across a drowner who could speak and he claimed he's not a drowner. I killed him and his corpse changed into the body of a woman. I've killed...something - and took the doll. (135 XP)

Gratitude
When I asked the girl about the talking drowner she suddenly changed. She claimed that she never asked me to find the doll, and she didn't know what I was talking about. Then she hid in her house. Girl denied that she ever asked me to find her doll. Кукла (квест)
