You have to protect Kinelory as he makes her way around the farm (counter-clockwise inside the cliffs) to the house on the opposite side where you have to defeat the undead Apothecary Jorell. I would strongly recommend taking out as many of the mobs outside the house as possible before allowing Kinelory enters; she doesn't pull the mobs as she walks past them (at least she didn't for me) but they come running once the fight starts. Apothecary Jorell is an easy fight alone, but it's very difficult to keep Kinelory alive against Jorell and three other mobs.
Once Jorell is slain Kinelory collects items from the house and then runs (and I mean RUNS) back to Quay around the upper rim of the cliffs (clockwise). There are only a few scattered orcs on the way back, but she really books it so "stay on your paws" :-)
If Kinelory dies, abandon quest, run back to Quay and wait for Kinelory to respawn (about 5 min for me).
Edit: can't spell to save my life
