Well written. Funny...out loud gafawing funny. Fun. Well crafted plot. Wonderful characters.
Format: Kindle
What a lovely surprise! A well written, well plotted. Funny. Fun. Mystery with two fresh and fine friends...Lady Hardcastle and Flo Armstrong , her erstwhile Lady's maid, Servant, Strong Right Hand Woman and friend...and...Inspector Sunderland, who finds the two so innovative and essential to the investigation of Two Murders and Some serious thefts that he is determined, and says so, that whenever they can he desires them to assist in future! I so enjoyed this first book in the series I invested in the next four...so far!...in the series. What fun...the women and now the Detective Inspector, as well, have such comical and engaging exchanges one finds herself (me) laughing so heartily she needs to pause and wipe her eyes repeatedly as she reads the story! Would highly recommend this series to anyone who loves a good, well plotted mystery and a giddy, heartfelt laugh...well, series of laughs, at the same time. Dialogue is often funny...though murder and mayhem are not!...and this is a careful blend of both....just sayin'. What a wonderful edition to a huge genre of cozy and some not so cozy mystery books. I recommend this series.

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.
