As much as Beatrice Hyde-Clare relished the challenge of figuring out who murdered a fellow guest during a house party in the Lake District, she certainly does not consider herself an amateur investigator. So when a London dandy falls dead at her feet in the entryway of a London Daily Gazette, she feels no compulsion to investigate. It was a newspaper office, after all, and reporters are already on the case as are the authorities.

Having solved the two murders that somehow fell in her path, Beatrice Hyde-Clare is on the lookout for a third. Through a absurd quirk of stupid fate, the shy spinster has fallen in love with the thoroughly unattainable Duke of Kesgrave and is desperate for something, anything, to occupy her mind. A dead body would do nicely.

Having long abandoned any hope of making a match, 26-year-old Beatrice Hyde Clare finds herself a little overwhelmed by her engagement to the Duke of Kesgrave. Cloying society matrons clamor for her attention while her aunt reels off an endless list of servants she will have to oversee. Even the most intrepid female would quake at the prospect of managing eight footmen! Fortunately, Bea knows the perfect distraction - an intriguing mystery - and pays a call on the Countess of Abercrombie, who had promised her that very thing only the evening before.    

Having inexplicably nabbed the duke of Kesgrave, 26-year-old spinster Beatrice Hyde-Clare is determined to marry him at once, and no amount of hand-wringing from anxious family members, worried friends, and well-meaning acquaintances will convince her to delay. Except, maybe, she is a little swayed by her uncle’s efforts to make amends for treating her with cold indifference during her childhood.

The former Beatrice Hyde-Clare is having a little trouble adjusting to her new situation. Now installed as the duchess of Kesgrave in elegant splendor in Berkeley Square, she is confounded by the stately residence’s seemingly endless array of rooms. And every time one of the maids addresses her as "your grace", she flinches.

When the curse changes inside Hannah, the mission to find a cure intensifies. Meanwhile, Hannah and Wycliff continue to investigate Unnatural murders, even as the cases circle closer and closer to home. 

Since the new Duchess of Kesgrave cannot be swayed from her unfortunate interest in dead bodies, Lady Abercrombie decides to confront the matter head-on by hosting a murder mystery dinner party. Gathering together several of society’s most influential members, she concocts an amusing puzzle-play, assigns roles, and stands back to allow Bea to impress them all with her ingenuity.

Despite suffering a few initial setbacks, the former Beatrice Hyde-Clare has settled into her new position nicely. Thanks to Lady Abercrombie’s machinations, she has secured the admiration of society and finally earned the respect of her staff. Even the lessons in defending herself, which her husband, the Duke of Kesgrave, insists she take if she wants to continue in her dangerous avocation, are going well. But then she learns from a most unlikely source that Kesgrave’s malevolent uncle is scheming to destroy her happiness.

Onetime adventurer and now amateur sleuth Lady Eleanor Swift is attending the annual royal regatta with her new pal Tipsy Fitzroy. Tipsy has Eleanor trussed up like a debutante in a new dress, determined to turn her into a proper society lady. Even Eleanor’s favorite companion, Gladstone the bulldog, has a new outfit for the occasion. But the sparkling prize-giving ceremony is interrupted when the devilishly handsome host gulps his glass of champagne on stage and collapses to the floor. The victim is none other than the king’s cousin, Lord Xander Taylor-Howard.

Winter, 1933. Kitty Underhay is enjoying a restorative break from sleuthing on a visit to her family at Enderley Hall. The only thing marring her peace - aside from the uncomfortable sensation she has of being watched - is the obvious history between her beau, ex-army captain Matthew Bryant and another guest, the beautiful Juliet Vanderstafen. So, when the parish clerk is found dead on her front doorstep, Kitty leaps at the chance of distraction. 

The newly married Lord and Lady Wycliff are cordially invited to a house party - to be mocked and ridiculed as entertainment. Wycliff insists on attending to discuss business with the host, while Hannah longs to hide in the library with its rare volumes on the Fae. Bound to Wycliff even beyond death, Hannah wonders how she will survive the week, when a guest unexpectedly expires.

November 1933. Amateur sleuth-cum-dutiful granddaughter Kitty Underhay stifles a sigh of boredom as she attends the annual Hoteliers' Association Dinner and Dance on behalf of her grandmother, the proprietress of the Dolphin Hotel. She hopes the company of ex-army captain Matthew Bryant will enliven the otherwise dull evening. That is, until bullish and overbearing local councilor Harold Everton drops dead into his bowl of consommé. 

A new unnatural horror is about to rattle Hannah Miles' quiet existence, and it's not the short-tempered viscount prowling the hallways. Someone is creating a monster by stitching together pieces of different people. When a limb makes an escape attempt, Viscount Wycliff is called to investigate. All of London knows there is one mad scientist among them capable of creating such an ungodly monster...Sir Warren Miles.

The year 1934. Kitty Underhay steps out of the battered Rolls Royce and onto the graveled driveway of Thurscomb Castle in deepest Yorkshire. She’s honored to be a bridesmaid at her cousin Lucy’s wedding to the reluctant Lord Rupert Woodcomb, but as family and friends gather for welcome drinks, Kitty dodges intrusive questions about her own marital status by taking a stroll about the castle grounds. As she passes through the manicured gardens, a fatal shot rings out....

Summer 1933. Fresh from the discovery that she has family living nearby, Kitty Underhay has packed her carpet bag, commandeered a chambermaid and set off on a visit to stately Enderley Hall. She’s looking forward to getting to know her relatives, as well as the assembled group of house guests. But when elderly Nanny Thoms is found dead at the bottom of the stairs after papers of national importance are stolen, Kitty quickly learns that Muffy the dog’s muddy paws on her hemline are the least of her problems.
