A house in one of London’s most exclusive neighbourhoods is home to secrets, mysteries, and two love stories spanning two centuries. In 1859, independent-minded Kitty Cathcart dreams of escaping Veronica Gardens but her father’s determination to marry her off to a rich man of his choosing forces her to seek happiness and find her own voice by other means. And then the handsome but poor Alex Faraday walks through the front doors. In 2019, Oxford-educated Josie Minton never dreamt of living in a house as grand as Veronica Gardens, but the nanny’s quarters are a perfect fit for a young woman in need of a job. Wealthy financier James Cavendish and his twin girls quickly find her indispensable to their happiness, but Josie is still searching for her future. Then the great house reveals the first of its secrets, and the tragedy and romance of one era are brought into sharp relief with another.
