There's a lot of good stuff in here and you get it across in very few words – well done.
There are a lot of potentially good stuff in here – who's sending us on this mission? What made some go mad and others survive (for now). I would love to have more of that sweet sense of a town in knees, trapped by winter, hunger and the undead. "23 mutilated bodies inside and 7 Risen Ghouls which feast on them." I mean if that doesn't spark images I do not know what will! And the fact that I imagine my group would rip the heart from the girls chest and flee while the parents battled it out is just freaking dark. Great writing.
The wife is in the mayor's home, so the population would be 3? Or doesn't she count because she is a Ghoul? It's not a big thing, it's just a ruling I would have to do, just had me wondering if you intended something different. :)
You could consider using Italic when you write out speech, and then do bold when monsters and NPCs appear? Would maybe help me scan the text.
All in all, short sweet and super clear. Really liked it. Well done.
