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. 

Late summer 1933. After a quarrel with too-plucky-for-her-own-good amateur sleuth Kitty Underhay, dashing ex-army captain Matthew Bryant is nursing his wounds, and a tumbler of brandy, when there’s a heavy knock at the door and he finds himself arrested for murder. The body of aspiring actress Pearl Bright has been found, strangled with one of Matt’s own bootlaces, and the evidence seems to be stacked against him. The local constabulary might have locked Matt up, but before they can throw away the key, Kitty hears the news and hies to his aid, determined to prove his innocence. 

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. 

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. 

England, 1920. Eleanor Swift has spent the last few years travelling the world: taking tea in China, tasting alligators in Peru, escaping bandits in Persia and she has just arrived in England after a chaotic 45-day flight from South Africa. Chipstone is about the sleepiest town you could have the misfortune to meet. But then, from the edge of a quarry, through the driving rain, Eleanor is shocked to see a man shot and killed in the distance. Before she can climb down to the spot, the villain is gone and the body has vanished.

It's 1920, and Christmas is coming. Major Lennox finds a body on his doorstep - why on his doorstep? Was it to do with the Countess? Was it about the ruby necklace? Lennox goes to Melrose Court, home to his uncle, Lord Melrose, to uncover the mystery. But then, the murders begin, and it snows, and it all becomes very complicated.

Autumn, 1920. Lady Eleanor Swift, accidental amateur detective and retired explorer, is determined to take a break from investigating murders. So when a local politician dies suddenly at an elegant dinner party at Farrington Manor, she tries her hardest not to listen to the raft of rumors around the village that he might have been poisoned by the fudge. It’s the anniversary of the disappearance of her beloved parents, and she’s promised herself not to get mixed up with any more mysteries. She isn’t sure they’d have approved.  

Who killed Sir Crispin Gibbons? A wedding invitation and news of mischief that could be murder takes Lennox to the Earl of Bloxford's country estate. He, soon, finds himself in a world of purloined artworks, forgeries, and a priceless Bloxford beauty. But who are the Bloxford beauties? And why are they the focal point around which death swirls?

A centuries-old skeleton is discovered in a lonely Scottish Castle. It wears a crown and hides a curse. Swift, the detective friend of Major Heathcliff Lennox, now lives at Braeburn Castle, and it was he who uncovered the skeleton. As ghosts are heard and treasure-seekers appear, the murders begin. Lennox must go to Braeburn and investigate as Halloween draws near.

There's a damsel in distress and accusations of attempted murder flying around, but it's not in the comfortable confines of the English countryside; it's in the very distant city of Damascus. Lennox must go and investigate, although he's not too keen on exotic locations, and his old retainer Greggs is distinctly averse to the very idea. Nevertheless, ex-Chief Inspector Swift persuades them, and they reach the ancient city to discover a movie crew, a spy, and a couple of mysterious ladies.

Winter, 1920. Amateur sleuth Lady Eleanor Swift is feeling festive. She is playing host to the entire village at Henley Hall. She’s also purchased perfect presents for each of her household - not forgetting the biggest bone in the butcher’s shop for her partner in crime, Gladstone the bulldog - and is looking forward to celebrating her first English country Christmas. As snowflakes fall, Eleanor is cheering on contestants in the traditional Christmas fun run in the grounds of the hall. But tragedy strikes when one of the runners drops dead at the finish line.

A scoundrel lies dying, and he makes his confession; his sins were despicable, and he wants to atone for his wasted life. He bequeaths an invaluable gift to Monks Hood Abbey, an ancient monastery set in a lonely corner of the Yorkshire moors. But sin throws a long shadow and corruption crawls in its shade. Strangers come forward and lay claim to the monks' inheritance.

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....

1934. Accidental amateur sleuth Kitty Underhay is being escorted by ex-army captain Matthew Bryant on an errand of mercy, as she takes a basket of grapes to her nemesis Mrs. Craven, who is recuperating from a recent operation. But their arrival at Elm House Nursing Home coincides with the mysterious death of Lady Wellings, a long-term resident.

August 1911. Emily Hardcastle and her inimitable lady’s maid Florence Armstrong are enjoying a fine summer until Harry, Lady H’s brother, turns up out of the blue with a mystery for them to solve. A routine parachute test at a local aeroplane factory has gone horribly wrong - with pilot Dickie Dupree plummeting to his death. Harry is certain there is more to this ‘tragic accident’ than meets the eye, having discovered that someone at the airfield is leaking top secret intelligence to foreign rivals.
