a quiet life???
This is a short story collection like Sir Arthur Conan Doyle and Agatha Christie have for Holmes and Poirot/Marple.
The characters remind me of the Phryne Fisher books. There are four stories in Book 1
A Quiet Life in the Country
Lady Emily Hartcastle and her maid Miss Florence Armstrong are enjoying some time in the country in the small
town of Littleton Cotterell when they come across a dead body. They find out that it is Frank Pickering, a local man
and it is thought that he committed suicide. But investigating, it seems that he has been murdered. Who
did it and why?
The Circus comes to town
Lady Hartcastle meets an old friend George who is the manager who for a circus that has come to
town. The next day, the juggler Hubert 'Huey' Parving is found dead mawled in a cage and then
others began to die. Who is behind this?
The Case of the Missing Case
Lady Hartcastle and Flo go to the engagement party of young Clarissa Farley-Strouds. The
next day, Nelson Holloway, the trumpet player with that night's entertainment - Roland Richman's
Ragtime Revue. Who killed him? As they investigate, the clues lead them to possible cursed
stolen jewel.
The Half-Death of Gunther Ehrlichmann
Florence recounts her life before and after meeting Lady and Lord Hartcastle as she and
Lady Hartcastle along with Lady Hartcastle's brother hunt down a killer.
Each story is tied into the other, but exciting! Must read!

Fun Seeing Where it All Begins for the Fantastic Amateur Detecting Duo
Format: Audiobook
I started with book three in this series, progressed forward, and finally took the opportunity to go back and get the first book in the series. The whimsical, cozy mystery paired with historical Edwardian setting was light and whimsical.
Actually, when I started listening, I realized that the first book introduced Lady Hardcastle and her ladies' maid, Florence Armstrong along with their new home and the other regular characters, in such a way that it didn't feel like the first book so much as the first of the stories that had been recorded. There are hints of their unusual, dangerous work abroad and no big explanation why the pair happened to be set upon 'a quiet life in the country' or why Lady Hardcastle and Florence have a relationship that is nearly family rather than an employer and servant from separate classes. The author trickles out the details and the reader/listener must catch them and piece them together as they go. Because I had experienced later books, those pieces stuck out easily to me. The meeting with Inspector Sunderland and the local villagers and neighborhood was fun.
There are two murder mysteries that have interesting crossover people and facts. One seems to involve a dead man from the village cricket team whose death was meant to appear like a suicide and then later, the death of a rag-time band trumpeteer that played at the engagement party of the local squire's daughter. A theft is tossed in for good measure.
I figured out one of the murders and part of the theft and the second murder, but the ultimate solution took me by surprise. Loved seeing the intrepid Flo able to get in some of her martial arts ability and spend time trailing along as they teased out the solution along side Inspector Sunderland.
Elizabeth Knowelden is an absolute gem of a narrator and the voice of this series for me. She laid out the Edwardian country village world, the variety of genders and accents, and kept the pace and tone for this series just right.
All in all, I thought this first entry was as fabulous as the later books and do not hesitate to put it out there as a good bet for historical cozy mystery lovers.

A story about what's left behind after death, both emotionally & spiritually - oh, and evil puppets
Format: Kindle
It takes a bit for Grady Hendrix's How to Sell a Haunted House to get to the "haunted" part of that title, but that's okay, really; what Hendrix is interested in here, as much as anything, is haunting in terms of the literal things left behind by death - the traumas that are left for those who survive, the guilt, the shame, the baggage, and all of the other things left behind by those who went before us. And, in the case of Louise and Mark Joyner, puppets. Lots and lots and lots of puppets. Oh, and one of them might be alive and malevolent, turning all of that metaphorical trauma into a very real presence (and, without getting into spoiler territory, all without losing that symbolic weight) - and one that allows Hendrix to bring real horror into the story of an estranged pair of siblings forced back into contact in the weight of their parents' death, and the reckoning that they have to go through as they deal with painful memories and a nightmare puppet. The end result can feel a little cluttered at times (although, by the end, it turns out to be a lot more interconnected and structured than you might realize along the way), and it doesn't help that it features some very fraught family interactions that cross from "painful" to "infuriating" very quickly. But as ever with Hendrix, there's more heart and emotion here than you might expect, and while it's all handled in his usual slightly off-kilter and unique sensibility, it still knows how to deliver the goods both on a horror front and a character one. I'd put it among the weakest of Hendrix's efforts overall, but there's a caveat here, and it's that I don't think anything he's read has ever been anything less than entertaining and solid overall, so even a weaker entry? Still a good time and a good read.
