After a confrontation at home, Hallam runs away to Edinburgh. The Obsession:
as Alasdair : The hotel manager and Kate's married lover. Key Themes and Style Hallam Foe (2007) - IMDb
As Hallam searches for his father, he encounters a complex and troubled individual who is haunted by his own past. Douglas is a married man with two children, but he is struggling to come to terms with his own identity and sense of purpose. The two begin to form an uneasy bond, and Hallam becomes drawn into his father's world.
The world had narrowed for him the year his mother died. Everything irrevocably altered after the funeral: the neighbors who used to bring casseroles fell silent; his father, once loud and easily readable, folded into a darker, unpredictable version of himself. Hallam’s way of coping — or of feeling safe — was to watch. To read people’s faces the way other people read books. He taught himself to notice the tilt of a shoulder that meant someone was about to lie, the way a laugh that didn’t reach the eyes belonged to a hurt that would not speak. Watching kept him feeling less alone. It kept him from falling into the same rooms of hurt that swallowed his father.
