Marlen Haushofer - A manzárd

The attic
The woman is the wife of a lawyer and the mother of two children. For the sake of her husband, she gave up her work as a graphic designer to devote herself to the household and raising children. He has only one refuge left, where he can be alone and indulge his passion, drawing, turning his back on the gray everyday life: the attic of the house. Here you open the mysterious envelopes you receive in the mail from a mysterious stranger. The envelopes contain details of his own youthful diary, from a long-forgotten period of his life. The woman mentally returns to the former location. She was happy in the solitude of the small mountain hut - until the moment when a strange and terrifying stranger appeared in her life...

We kill Stella
A woman turns a blind eye to her husband's women affairs in order to create the appearance of perfect family harmony in front of her son. She does not intervene when the man seduces the 19-year-old Stella, the daughter of the woman's former schoolmate, who is accepted for a school year.
