It’s 1941, and the Mitford household is splintered by the vicissitudes of war. To bring the clan together, Deborah invites them to Chatsworth for Christmas, along with a selection of society’s most impressive and glamorous guests, as well as old family friend Louisa Cannon, a private detective. A psychic arrives one night, and to liven things up Deborah agrees she may host a séance. But entertainment turns to dark mystery as the psychic reveals that a maid was murdered in this very same house --- and she can prove it. Louisa steps forward to try to solve the cold case. But with a house full of people who want nothing more than to bury their secrets, will she be able to unmask the murderer? And how deep does the truth lie?

Bella and Kate. Kate and Bella. From childhood they were bosom friends --- Bella sensible and cautious, Kate gregarious and just a little dangerous. Yet, in spite of their intimacy, their trust is fragile. Men came into their lives, and things changed: a black seed was set in the heart of their relationship. Over decades, acts of both cruelty and love ferment until one shocking event tests them more than ever. Neither will escape unscathed.

1937. War with Germany is dawning, and a civil war already rages in Spain. Split across political lines, the six Mitford sisters are more divided than ever. Meanwhile, their former maid, Louisa Cannon, is now a private detective, working with her policeman husband, Guy Sullivan. Louisa and Guy are surprised when a call comes in from novelist Nancy Mitford requesting that they look into the disappearance of her Communist sister, Jessica, in Spain. But one case leads to another as they are also asked to investigate the mysterious vanishing of a soldier. As the two cases come together, Louisa and Guy discover that every marriage has its secrets --- but some are deadlier than others.

It's lady's maid Louisa Cannon's wedding day, but the fantasy is shattered shortly after when she is approached by a secretive man asking her to spy on Diana Mitford --- who is having an affair with the infamous Oswald Mosley --- and her sister, Unity. Thus, as summer 1933 dawns, Louisa finds herself accompanying the Mitfords on a glitzy cruise, full of the starriest members of Society. But the waters run red when a man is found attacked. Back in London, the case is taken by lawyer Tom Mitford, and Louisa finds herself caught between worlds: of a love lost, a family divided and a country caught in conflict.

The year is 1928, and after the death of a maid at a glamorous society party, fortune heir Bryan Guinness proposes to 18-year-old Diana, the most beautiful of the six Mitford sisters. The maid's death is ruled an accident, and the newlyweds put it behind them to begin a whirlwind life zipping between London's Mayfair, chic Paris and hedonistic Berlin. Accompanying Diana as her lady's maid is Louisa Cannon, as well as a coterie of friends, family and hangers-on, from Nancy Mitford to Evelyn Waugh. When a second victim is found in Paris in 1931, Louisa begins to see links with the death of the maid two years previously. Now she must convince the Mitford sisters that a murderer could be within their midst.

Meet the Bright Young Things, the rabble-rousing hedonists of the 1920s whose treasure hunts were a media obsession. One such game takes place at the 18th birthday party of Pamela Mitford, but ends in tragedy as cruel, charismatic Adrian Curtis is pushed to his death from the church neighboring the Mitford home. The police quickly identify the killer as a maid, Dulcie. But Louisa Cannon, chaperone to the Mitford girls and a former criminal herself, believes Dulcie to be innocent, and sets out to clear the girl's name…all while the real killer may be only steps away.

It's 1920, and Louisa Cannon dreams of escaping her life of poverty in London. Louisa's salvation is a position within the Mitford household at Asthall Manor, in the Oxfordshire countryside. There she will become nursemaid, chaperone and confidante to the Mitford sisters, especially 16-year-old Nancy, an acerbic, bright young woman in love with stories. But then a nurse --- Florence Nightingale Shore, goddaughter of her famous namesake --- is killed on a train in broad daylight, and Louisa and Nancy find themselves entangled in the crimes of a murderer who will do anything to hide their secret.
