Dana Morrow is literary lecturer who is investigating Marianna, a tragic 19th century medium, for an article. She feels lucky to be invited to the vary house where Marianna lived. The house, an isolated mansion by the English coast, is now owned by Finn, a renowned photographer who has records concerning Marianna's life. Once there, Dana finds herself amid a chaotic collection of guests who have an interest in a coming retrospective of Finn's work.
Dana remains on the edge of the group as she pursues her project. Nevertheless, she is drawn to other fringe characters, including Finn's adult son, Daniel.
Llewellyn develops each character at the mansion, making this something of a literary novel. Likable and unlikable characters have their own problems and blessings as they engage in backbiting, gossip, opinions on photography, and, in passing, mention the Gull, a serial killer haunting the cliffs of the area. He could be any one of the guests.
We follow the background and aims of each character and the relationships they maintain with one another. Consequently, we become invested in each character as we follow developments. The story seems removed from a developing murder mystery, but offhand mentions of the Gull who has claimed a new victim keep us alert. Eventually the Gull encroaches on the lives of our heroes.
From the novel's beginning we get a sense of the ominous. Individuals are vividly portrayed, as is the weather and countryside. Tension is kept alive by the attitudes of the characters as they play out their relationships. Eventually the tension reaches a crescendo as the Gull emerges, and a life and death struggle carries us through the final pages.
