That is, until bullish and overbearing local councilor Harold Everton drops dead into his bowl of consommé. 

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.

The year 1934. Kitty Underhay steps out of the battered Rolls Royce and onto the graveled driveway of Thurscomb Castle in deepest Yorkshire.

Kitty Underhay is looking forward to a week of long lunches and wedding planning with her husband-to-be, Captain Matthew Bryant. But the plan is derailed when he is called on to collect a former comrade-in-arms, arriving on the 15:50 from Paddington. As the train bearing Simon Travers pulls up to the platform, a piercing scream rises over the screech of its brakes. Travers is dead in his seat, a dagger in his heart. Only a few individuals had access to Travers’s compartment, and Kitty must find out which of these seemingly benign passengers is, in fact, a cross-country killer.

Spring, 1921. Lady Eleanor Swift, explorer extraordinaire and accidental sleuth, hasn’t had a vacation since she arrived in England a year ago. So she books into the Grand Hotel in the fashionable resort of Brighton for some fresh air, fish and chips, and, of course, a dip in the ocean. Eleanor is enjoying her view of the waves and trying to find her bathing suit when calamity strikes: A guest has been found dead at her beautiful hotel. The distraught manager, who can’t afford a scandal, asks Eleanor to solve the case as swiftly as possible.

A scoundrel lies dying, and he makes his confession; his sins were despicable, and he wants to atone for his wasted life.

Strangers come forward and lay claim to the monks' inheritance.

The victim is none other than the king’s cousin, Lord Xander Taylor-Howard.

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.

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.

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.

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.

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.

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.
