A sudden interest in the occult swept through the English village of Plummergen, with Ouija boards replacing the best china in many a cozy cottage. It might be quite the thing for maiden ladies and persnickity aunts, but it wasn't Miss Seeton's cup of tea...until Scotland Yard requested she go undercover to investigate some sinister shenanigans in the Kentish countryside. A flim-flam was afoot in the local witches' coven...and magic could be a prelude to murder most foul.

When a flood of perfectly faked banknotes hits the market, retired art teacher Miss Emily Seeton, the Yard's famed ‘MissEss', is chosen to investigate a respected Geneva bank. Somehow, the forger is also mixed up in the theft of valuable paintings, so it's ‘set an artist to catch an artist.' But Miss S. is new to air travel – surely the names Geneva and ‘Genova' must be the same place? Bamboozling both the crooks and the police who vainly try to keep tabs on her, innocently humming the fraudsters' musical password, she trips gaily along the dangerous trail. Serene amidst every kind of skullduggery, this eccentric English spinster steps in where Scotland Yard stumbles, armed with nothing more than her sketchpad and umbrella!

After her father's death, Kate was left an orphan, striving to make ends meet as a governess until her Aunt Minerva rescues her from poverty. Kate hardly knows what to expect at the grand house of Staplewood. Her uncle lives in one wing, while her handsome, moody cousin, Torquil, occupies another; guests are few and far between, but even family dinners are rigidly formal. And, over it all, Minerva's word is law. But the sudden arrival of Cousin Philip throws Minerva's control over the household into doubt, and Kate begins to suspect the shocking reason for Minerva's generosity. 

When Miss Seeton walks out after a performance of Carmen and witnesses a real-life stabbing, all she can recall is a shadowy figure. But how could she have guessed that her latest artistic endeavor is a picture-perfect portrait of the killer? Her sketch puts her in a perilous position, for back at her recently inherited cottage in Plummergen village, she's fated to be a sitting duck...for murder most foul!

A former CIA operative turned art dealer waits in Italy, wounded and in hiding, for the cavalry. According to his SOS, only Mrs. Pollifax will do....

The first informant is murdered just after Mrs. P. identifies him in Fez. Worse, she has the frightening sensation that her associate is not who or what he says he is.

Her favorite teacher, Mrs. Wadsworth, has asked that Eleanor talk about her intrepid travels around the globe - travelling the Silk Road by bicycle, crossing the Himalayas and even befriending the Maharaja of India.
