High-spirited Lydia expects a very dull visit, but her sojourn to the village of Diddlington is not as idyllic as she anticipates . . . A charred and bludgeoned corpse is found in the woods, and suspicion falls on Lydia's aunt's suitor, an intriguing Frenchman. Convinced of his innocence, Lydia enlists the help of her new friend, John Savidge, to catch the real killer.

Marianne Edgewood is perfectly capable of running Brindale Castle, if only the task would be left to her. A centuries-old house of stone is solid, unchanging, whereas people are not to be relied upon. It matters little that a stranger inherited the castle. She must simply find a way to stay.

A murdered opera singer. A duke drenched in her blood. For Bow Street Officer Hugh Marsden, the brutal killing is a straightforward case. Ever since his exile from polite society, the chance to arrest a high and mighty peer of the realm has never presented itself. Hugh won't snub the opportunity now. But Audrey Sinclair, the Duchess of Fournier, is certain her husband is wrongly accused, and she's determined to prove it to the arrogant Bow Street officer, even if she must employ her most peculiar ability—or perhaps curse—to guide her investigation. After all, a duchess can do as she pleases.

Miss Amelia Fleming has a very good reason to hate the Earl of Langley. A year ago, her father drowned in the Thames after losing a fortune to Langley at cards. Now her family is broke, her fiance has broken their engagement, and the debt still hasn't been paid. Someone has to deal with the earl, but Amelia's brother doesn't have the nerve and her mother has fled to France. It's no business for a gently bred young lady, but the Earl of Langley is about to learn that Amelia Fleming is not your typical young lady . . .

Miss Marianne Beaumont, a spinster, and her younger sister are on their way home from a night at the theater when they come upon a townhouse fire. They stop to help the victims, including Mr. James Harcourt, a confirmed bachelor, and his parents Sir and Lady Harcourt. Although Mr. Harcourt distrusts the beau monde, he accepts Marianne’s ministrations. That should have been the end of their association, but then a folded piece of paper shaped like a chameleon slips out of his mother’s sleeve. It’s an ornament Marianne has come across only one time before—next to her father’s dead body.

Tabitha, Lady Chesterton, the Countess of Pembroke, is newly widowed at only 22 years of age. With no son to inherit the title, it falls to a dashing, distant cousin of her husband's, Jeremy Chesterton, known as Wolf. It quickly becomes apparent that Wolf had consorted with some of London's most dangerous citizens before inheriting the title. Can he leave this world behind, or will shadowy figures from his past follow him into his new aristocratic life in Mayfair? And can Tabitha avoid being caught up in Wolf's dubious activities?

Twenty-six-year-old Beatrice Hyde-Clare is far too shy to investigate the suspicious death of a fellow guest in the Lake District. A spinster who lives on the sufferance of her relatives, she would certainly not presume to search the rooms of her host's son and his friend looking for evidence. Reared in the twin virtues of deference and docility, she would absolutely never think to question the imperious Duke of Kesgrave about anything, let alone how he chose to represent the incident to the local constable. And yet that's exactly what she does.

When 17-year-old Marie Sinclair travelled to Strathlinn in Scotland in 1920 to visit her brother and his new family, all she was looking for is rest and recuperation after the death of Lady Hanley, for whom she had been caring for over the past 18 months. But when her pregnant sister-in-law is rushed to hospital, Marie is forced to take on a far greater role in the lives of her Scottish family. And who is Mark Blackford, the new, young Estate owner? Meeting him on the train to Strathlinn, Marie's life becomes entwined with his, as friend, help-meet, and, maybe, something more?

Hours later, the man’s cold body lies in the city mortuary, alongside the woman he couldn’t save. And his sister, unconventional nurse Gemma Tate, tracks down troubled police inspector Sebastian Bell to unravel the truth. Sebastian has enough pressure to solve the murder of an aristocratic heiress without Gemma meddling in his case. But the cryptic sentences she brings him from her brother’s notebook could be a crucial lead. If only they knew what “milky way” meant.

When the family receives a second photograph of their daughter, who is quite obviously dead, their simple inquiry becomes a murder investigation. But this is no routine investigation as another photograph is received, and another body is found. As more bodies turn up, and with no known motive, Brodie and Mikaela must confront the fact that the murderer is brilliant, disturbingly talented, and quite possibly insane. What drives this cold-blooded killer to capture the last moments of their victims with such haunting clarity?

Reverend Augustus Shackleford's mission in life (aside from ensuring the collection box was suitably full every Sunday) was to secure advantageous marriages for each of his eight daughters. A tall order, given the fact that in the Reverend's opinion they didn't possess a single ladylike bone in the eight bodies they had between them. Quite where he would find a wealthy titled gentleman bottle headed enough to take any of them on remained a mystery and indeed was likely to test even his legendary resourcefulness.

When Lady Henley Killigrew's father dies and his title of earl passes to a not-so-friendly cousin who wants her and her two younger sisters out of their elegant London townhouse, she takes them to Moonstone Cottage, a lovely manor house they inherited from a maiden aunt in the Cornwall seaside village of Moonstone Landing. But their funds are limited, and the new earl is a stingy guardian who will not loosen the purse strings to allow her to properly maintain herself and her sisters in their new home. The only way to save them all is for her to marry.

Nothing can tempt him to remain, not even Lily, the beautiful bluestocking determined not only to restore relations between him and his grandfather, but to turn Ewan into a proper gentleman.

Jostling for attention are two lords.
