Paris, 1939. Hollywood actress Drue Leyton, married to Frenchman Jacques Tartière, lives as an expatriate in love. But when her husband is dispatched to Brittany to work as a liaison for the British military, Drue finds herself alone with her housekeeper. With her career and fame 4,500 miles away, she accepts an opportunity that will change her life forever. Befriended by seasoned wartime journalist Dorothy Thompson and urged on by political operative Jean Fraysse, Drue broadcasts radio programs to the United States. Her duty: shake America from its apathy and, as Nazis encroach and France is occupied, push for resistance and help from the US. As Drue and Jean fall under suspicion, Hitler sends his own message: when Drue’s adopted country is conquered, she will be executed.

In the summer of 1973, Ruth and her four friends were obsessed with pre-Raphaelite paintings. Drawn to the cold depths of the river by Ruth’s house, the girls pretend to be the drowning Ophelia, with increasingly elaborate tableaus. But by the end of that fateful summer, real tragedy finds them along the banks. Twenty-four years later, Ruth returns to the suffocating, once grand house she grew up in, the mother of young twins and 17-year-old Maeve. Joining the family in the country is Stuart, Ruth’s childhood friend, who is quietly insinuating himself into their lives and gives Maeve the attention she longs for. She is recently in remission, unsure of her place in the world now that she is cancer-free. Her parents just want her to be an ordinary teenage girl. But what teenage girl is ordinary?

In August 1939, 30-year-old Hetty Cartwright arrives at Lockwood Manor to oversee a natural history museum collection, the contents of which have been taken out of London for safekeeping. She is unprepared for the beautiful and haunted Lucy Lockwood. For Lucy, who has spent much of her life cloistered at Lockwood suffering from bad nerves, the arrival of the museum brings with it new freedoms. But it also resurfaces memories of her late mother, and nightmares in which Lucy roams Lockwood hunting for something she has lost. When the animals appear to move of their own accord, and exhibits go missing, they begin to wonder what exactly it is that they might need protection from.
