Such à beautiful house!

A couple of students rent a house for the holidays from an old man who lives in obscurity. He and she are surprised, in the middle of the day, the curtains are drawn, there is a smell of mothballs, candles are lit, no trace of electricity. He is pale, almost stiff.
At the resort, they discover a mansion, the rent would be acceptable for a studio. The park is immense, an insane number of fruit trees, a garden with abundant vegetables. They will have to clean the house. It has no running water, electricity or gas. Sewerage is not provided, perhaps a luxury that the owner could not afford.
From the first days, strange things happen, a ghost seems to haunt the place. It's a haunted house, and yet they are far from Wales. It's not Halloween. Unexplained phenomena, they are paranormal, the word paranormal is dropped. It is not a castle, at most a manor, a beautiful bourgeois house. For some, the paranormal is also an attraction Appearances in the corridors, fear rears its ugly head.
Thrills, a labyrinth where you go in circles, ghostly terror, frightening facts, spending the night in this house is worse than sleeping in a cemetery. A white lady walks into the living room. They almost want to call a Sir Stephen and a lady named Mary. This residence is an enigma. Maybe a legend exists.
A monster which is undoubtedly only supernatural walks in the middle of the garden, a pack of wolves accompanies him. He wears a harlequin mask. It's a funny idea to have such pets.
A demon is surely shaking this world, he must have escaped from Edinburgh, a survivor of the Stuart clan. It would be easier to make a nocturnal visit to an asylum than to stay in this house at the stroke of midnight.
Wandering alone at night in the catacombs would be less frightening.
The inhabitants of the village tell them that the tenants of this place do not stay more than a week, they disappear during one night. The next day, the owner appears and locks the house. They hide behind the curtains to see him. Seeing him gives them chills. Being afraid is common among people down there. A pack of zombies is probably following him, a hypothesis, he's so weird.
The terrifying being appears to be the ghost of a nun belonging to a family who lived in this mansion. It undoubtedly has a history, you have to be a historian to find it among the myths, legends and slander.
The inhabitants seem to know the reason for the mysteries surrounding the house, but they remain silent.
A village shrew, a bad tongue, a rumor-maker, gets angry because they don't leave. The custom has broken, they stay inside the devil's house, yet everyone is really afraid of them. This building is haunting.
The couple of students seem to be living a horror film, thrills guaranteed, in this abandoned house. They become ghost hunters without wanting to. They will become masters in the art of spiritualism.
Not only that, but they look for the reason for the abnormal manifestations. It's not really a fairy story, but rather an escape game.
