Detailed Walkthrough
Gathering Healing Supplies
As you walk through the area near Hinault farm, you may find a Breton guardsman who is wounded and in dire need of assistance. Speak with him to start this quest and to learn what has happened at the farm. House Montclair has launched a vicious surprise attack and the Shornhelm Guard, led by Lieutenant Fairfax, are doing their best to hold their ground at the Old Tower that they have commandeered as their base of operations. Many guardsmen have fallen wounded and they are in need of healing supplies if they are to keep this up for much longer. Daribert was ambushed and injured while trying to gather these supplies and as such, he asks you to complete this task in his stead while he himself warns the rest of the troops of what has happened.

The healing supplies can be found in wagons scattered across the area surrounding the farm. Gathering the supplies is a straightforward process and the Montclair troops that you will most likely encounter while doing so should pose little in the way of a challenge. 

Once you have gathered enough healing supplies, it is time to speak with Lieutenant Fairfax, who can be found at the tower that Daribert mentioned. Understandably so after the Montclairs' surprise attack on this area, he is not enthusiastic about allowing a stranger into the tower, but quickly agrees to do so anyway after you mention that you have recovered his healing supplies.

Inside the tower, you can find Heloise tending to some wounded soldiers. Pleased with the healing supplies which she believes will make a significant difference, she has another task that she requires your help with. She tells you that she is worried about the Hinault family, none of whom has been seen after the beginning of the battle. She wants to check on them, but cannot do so without your help because of the threat that the Montclairs would pose to a lone healer like her.

Aiding the Hinault Family
She needs a bit more time inside a tower to finish tending to the soldiers' wounds and to collect herself and as such requests that you meet her outside the tower. When you do so, she states that she is ready to go to the farm and will lead to straight to it.
:Heloise Menoit: ''"This is the Hinault Farmhouse. Why don't you go up and see if anyone is home?"''

When you do as she suggests, you are addressed by a scared voice that comes from within and which tells you to go away. The voice is that of Gennove Hinault, the father of the family, who demands that you return with weapons for him and his family so that they can defend themselves when he opens the door for you. Every member of the family requires a different kind of weapon, but fortunately, and as Heloise helpfully points out, all of these can be found easily due to the farm being the site of a battle. 

When you return to the farmhouse after completing your task of finding the weapons, you will find the door unlocked and an evidently distraught Heloise inside. Lying on the ground before Heloise is the dead body of Gennove, who she says was already dead when she entered the home, most likely having sacrificed his life in an attempt to allow his family to escape from attackers. She requests that you find the four remaining members of the family - Gennove's wife, daughter and his two sons - and either bring them to safety or, if they have already been killed, burn their bodies and collect their ashes so that they cannot return as bloodfiends and their surviving family members can give them a proper burial once all of this is over.

Two of the four missing persons, Jowan and Mayla, are still alive and can be found cowering, terrified, at hiding places across the farm. Both of them mention a female creature that attacked and killed their father, after persuading him to open the door by claiming that she was concerned about their wellbeing and wanted to help. Unfortunately, the other two members of the family, Marrec and Melita, have already been killed. Both of them have been transformed into bloodfiends, whom you need to kill and burn in order to advance to the next stage of the quest.

After you have rescued Gennove's daughter and oldest son and have collected the ashes of himself, his wife and his youngest son, you need to return to the tower and speak to Lieutenant Fairfax. He is concerned about Heloise, whom he has not seen since she ran off after she had briefly returned to collect her healing kit while you were looking for the weapons that Gennove had asked for, and mentions that he thinks she is ill before suggesting that you head inside the tower to check on the Hinaults. 

An Unsuspecting Vampire
Speak with Jowan, who can be find near his sister inside the tower, to inform him of the bad news and deliver his relatives' ashes to him. However, your conversation with him will be interrupted when Heloise, whom Jowan and Mayla at once recognize as the one that killed their father, enters the tower.
:Mayla Hinault: ''"Divines protect us! It's the monster!"
: Jowan Hinault: "Stay back, foul creature!"
:Heloise Menoit: "Monster? What did I..."
:Jowan Hinault: "She's a bloodfiend! She entered our farmhouse and killed our father!"
:Heloise Menoit: "No! That can't be true!"''

Heloise then storms off, crying and leaving you alone with Jowan and Mayla. You can speak with them to gain further confirmation that they are certain that Heloise, in spite of what her appearance and seemingly good intentions might suggest, truly is the one who murdered their father. In order to reach the next stage of the quest, you need to leave the tower and track down Heloise. You must follow the trail of personal artefacts that she left behind while fleeing from the tower. These items, which include a book entitled Healing Herbs of Northwest Tamriel, her healing kit and backpack and some notes of hers, are all somehow related to her profession as a healer and will lead you to a shack where you can find Heloise. 

As Jowan and Mayla's words, in combination with some other foreboding signs such as her mentioning that she could smell blood coming from the farmhouse and Lieutenant Fairfax mentioning that he thought that she was ill but didn't want to let it show, might have already led you to conclude, Heloise is indeed a vampire. Her outward appearance reflects the change that was brought about by a seemingly minor injury that she sustained from a bloodfiend. You should speak with her to learn what has happened precisely. 
 
Heloise is still very confused by what has happened but gradually remembers that she has indeed killed Gennove and has drunk his blood. Scared of the change that has come over her and not trusting herself to remain in the vicinity of others whom she might hurt, she says that she will go far away from this area and will find a hiding place where she won't be at risk of harming anybody. 

What happens next is completely up to you. You can either decide that she is too much of a danger to be kept alive or show her mercy and allow her to flee from this place and find a way to cope with her newfound vampiric nature that does not involve harming others.  After you have made your decision, you should return to Lieutenant Fairfax to tell him what has happened and to finish the quest.
