context: Hallam Foe is a teenage loner who lives on his father's large estate near Peebles. His hobby is spying on people from his tree house. Hallam is convinced that his stepmother (Verity) is responsible for his mother's death by drowning two years earlier. Hallam's sister leaves home to attend university and it becomes clear that Verity and his father want Hallam to move on as well. Hallam initially refuses due to his suspicion of Verity, but she uses his diaries first to have sex with him and then to blackmail him into leaving. To escape his father and stepmother, Hallam travels to Edinburgh.
  Upon arrival in Edinburgh, Hallam sees Kate, an administrator at the Balmoral Hotel, located in the city centre. Kate bears a striking resemblance to his late mother. He manages to persuade her to give him a job as a kitchen porter in the hotel. Hallam makes his home in the clock tower of the hotel because of its vantage point over Kate's home in a top flat, where he can spy on her. He also spies on Kate through a skylight on her roof, clambering over the roofscape to reach his vantage point.
  Hallam learns that another senior hotel employee (Alasdair) is having an extra-marital affair with Kate. Alasdair then discovers Hallam's lookout in the clock tower. Hallam attempts to blackmail Alasdair with the knowledge of his adultery, but Alasdair dismisses him. Hallam retaliates by finding Alasdair's wife and child and thereby demonstrating the ability, if he wishes, to inform her of the affair, which forces Alasdair to give him back his job.
  Hallam eventually works his way up to being a front-of-house porter at the hotel. On his 18th birthday, Kate invites Hallam to have a few drinks after work. Whilst drunk, Hallam reveals his continuing love for his late mother. This seems to fascinate Kate, as she "likes creepy guys". A complex relationship starts to build between Hallam and Kate from this point.
  Kate first invites him home with her that night, and when she attempts to seduce him, he begins to get uncomfortable and instead they sleep in the same bed. The next day he asks her on a date and she rejects him, but later she asks him to one of the hotel rooms and they have sex.
  When Hallam is watching Kate, Alasdair confronts her and begins to act violently. Hallam comes through the skylight to save her, which results in her finding out that he had been spying. She tells Alasdair to leave. She punishes Hallam by making him stand nude and explain to her why he was spying. She feels bad for him after he tells her about his mother and she lets him stay. She puts on the dress that Hallam keeps that used to be his mother's, and when Hallam sees her he cries, and they fall asleep together.
  Hallam's father and stepmother track Hallam down at this time because Hallam had reported his suspicions about his mother's death to the police in Edinburgh. They track him down because his father has run up significant debts and needs to develop some of the land on the estate, but Hallam is entitled to consultation under his mother's will. Hallam refuses to co-operate due to his suspicion of Verity.
  Hallam's hatred of Verity consumes him entirely, and he tries to drown her in the loch by his father's house. However, his humanity takes over and he revives her. Only at this point does his father reveal that he had made no attempt to prevent Hallam's mother from committing suicide. This revelation allows Hallam to realise that his anger is in fact with his mother for leaving him. This cathartic moment enables him to move on for the first time and we leave him happy and content walking the streets of Edinburgh.
