Dear listeners,

Welcome to the first reading recommendations newsletter of 2026! Once a month, I pop into your inbox to share what the Shedunnit team — that is, me and my production assistant Leandra — have been reading while we are making the show. Perhaps you will find some inspiration for what you might read next here? I hope so.

Caroline Has Read: A Case of Life and Limb by Sally Smith

If you're a reader of my personal blog/newsletter, you might remember that in December 2024 I received Sally Smith's debut historical crime novel, A Case of Mice and Murder, as a Christmas present and had read it by the end of Boxing Day. Imagine my delight when I opened a present from my husband this Christmas and found the sequel! I once again dedicated most of the 26th to reading it in full and had a lovely time. I'm not sure that Smith writes "cosy crime" precisely, but I certainly had a very cosy time with this crime novel.

Once again, Smith takes us back to the Inner Temple in London in the early 1900s, with her barrister-detective Gabriel Ward as our guide. This time, the case he must unravel mostly takes place within the walls of the Inner Temple (an ancient and peculiar community of lawyers in the City of London) as various residents have been receiving unpleasant parcels containing body parts. I liked this inward focus, since I find the setting one of the most fascinating things about this book. I also enjoyed Gabriel's gentle character growth over this book as he begins to admit that he can make space in his rigid routines for the occasional friend or pet. Long may his adventures continue.

Caroline Will Read: Curiosity Killed the Cat by Joan Cockin

The Shedunnit Book Club is reading this 1949 detective novel about a murder in a village taken over by the Ministry of Scientific Research during WW2 as our book for February, so I will be reading this one shortly so I can make the bonus episode about it. I'm very intrigued — Cockin seems like a fascinating person and I have high hopes for her crime fiction.

Leandra Has Read: Nobody's Baby by Olivia Waite

In this second instalment of the Dorothy Gentleman sci-fi mystery series, a baby is discovered on board the HMS Fairweather. As the passengers are hundreds of years into their trip to a new Earth with medical intervention preventing procreation, such an occurrence should be impossible. Ship detective Dorothy Gentleman not only has to uncover how this child came to be but also why the mother doesn't remember having him. Could something more sinister be at play?

I received an advanced reader's copy of Nobody's Baby from the publisher, and as I enjoyed my time with the first book, Murder By Memory, I looked forward to this being my first read of 2026. It's the perfect series of novellas for those who gravitate toward cozy mysteries. It's more character-driven than plot-driven, and the setting of this luxury interstellar liner takes centre stage. It was a light, relaxing way to start of my 2026 reading.

Leandra Will Read: Lud-in-the-Mist by Hope Mirrlees

As the Shedunnit Book Club is celebrating the hundredth anniversary of The Murder of Roger Ackroyd in January, I have been slowly reading a 1926 fantasy classic with a friend. We started this title before the December holiday season but then set it aside until the new year. It follows numerous inhabitants of the fictional city, Lud-in-the-Mist, who are slowly realising that they have a fairy problem. While the city borders the land of Faerie, it has been decades since they've severed their connections with their neighbours. In recent weeks, however, children are suspected of eating fairy fruit, the ex-mayor witnesses blood trickle down from the lid of a coffin, and Master Nathaniel Chanticleer keeps hearing "the Note". I am about halfway through this narrative and thoroughly enjoying it. The writing is lush, filled with beautiful descriptions, but it's also whimsical and packed with odd, humorous moments. I hope the final half is just as strong!

That's how we're starting the year, book wise! What are you going to be reading? You can let us know by replying directly to this email or by leaving a comment to join the conversation with other readers. We're also going to be recording a bonus episode shortly just for Shedunnit Book Club members all about our reading intentions for 2026, so if you aren't already a member, you might like to join in time to hear that in early February.

Until next time,

Caroline

Dear listeners,

One of the many things that fascinates me about Agatha Christie's detectives is that I don't think she knew at the beginning how many times she would end up writing about them. The idea of the crime series built around a central sleuthing personality is so embedded now that I suspect most debut novelists have half an eye on the sequel potential of their protagonist even as they are constructing their first case. Not only did Christie not begin her first novel expecting to become a professional writer with a career spanning decades, she also didn't have ten Poirot sequels already in mind.

This is surely especially true of Mrs Oliver, who first shows up as a minor character in the Parker Pyne story "The Case of the Discontented Soldier", written in the early 1930s. I don't think Christie knew then that she would go on to write seven novels featuring this character, one of which has her as the sole detective. The evolution of Mrs Oliver (who acquires her first name, Ariadne, in her first novel length appearance) is fascinating, therefore. She grows and changes to meet the demands of each new novel that Christie wanted to put her in, rather than being a fixed personality that is slotted in, ready made, to new stories.

In the latest episode of Shedunnit, I've gone more deeply into the form and function of Ariadne Oliver in Christie's mysteries, and looked at the relationship between creator and character. Ariadne is often described as being a stand-in or self-insert for Agatha Christie herself. But is that really true?

Let's take a look at the full Ariadne Oliver canon.

Cards on the Table (1936)

This is a clever piece of formal experimentation that puts me in mind of some of Anthony Berkeley's 1930s detective fiction. An eccentric host invites four people he suspects of having got away with murder and four detectives to his house for dinner and cards. By the end of the night, he is dead, stabbed by one of his guests. Who did it? The personalities at the party, as revealed by their bridge playing, is vital to the solution of the case. It's something of a detecting super-group, with Christie bringing together four detectives she had used separately in other works: Hercule Poirot, Mrs Oliver, Colonel Race and Superintendent Battle. I like this book both for its cunningly-handled murder scenario and because it sets up what was to become a close and long-term relationship between Mrs Oliver and Poirot.

Mrs McGinty's Dead (1952)

After leaving Mrs Oliver in stasis for 16 years, Christie brought her out to act as a secondary to Poirot in this village mystery about the brutal murder of a cleaning lady. She is there by coincidence, not design, being introduced as an acquaintance of one of the households. She is working on a stage adaptation of one of her novels with someone who lives there — a reflection of the fact that Christie herself was also moving more into theatrical writing in the early 1950s.

Dead Man's Folly (1956)

This time, it is Mrs Oliver who calls in Poirot, but not initially to investigate a murder. She is staying at a country house (Greenway in disguise) and has been asked to create a murder mystery treasure hunt for the village fête. She is feeling uneasy about the process, but can't quite put her finger on why — a Mrs Oliver trademark. Certain aspects of her mystery are being changed as if someone is manipulating her for their own nefarious reasons. Not long after Poirot joins her, the murder mystery game becomes a real murder and we get to see Mrs Oliver in a more active sleuthing role. I especially like the evolution of her much discussed "women's intuition" from earlier stories. We see how seriously Poirot takes Mrs Oliver's feelings that something is not right in this book.

The Pale Horse (1961)

This is the only full-length novel in which Mrs Oliver appears without Poirot. She is consulted by the book's narrator, Mark Easterbrook, about another murky suspicious circumstance that may or may not be criminal: the possibility that a group of creepy women living in an old pub are running a magical "assassination to order" business. Through Mark's eyes, we get to see some of Mrs Oliver's creative process for her fiction and we learn that she had written 55 novels and counting. She gives him good advice about confronting evil. This book is also a key crossing-over point in the Christie canon. One of the characters from Cards on the Table recurs as a way to connect Mrs Oliver to the social circle and the area where the Pale Horse pub is. Also based here is the vicar's wife Mrs Dane Calthrop, who appears in 1942's The Moving Finger as the person Miss Marple is staying with while investigating poison pen letters in Lymstock. Thus, this novel confirms that Poirot and Marple exist in the same fictional universe, since via Mrs Oliver they now have a friend in common. I highly doubt that Christie thought or cared about such a detail, but I enjoy thinking about it.

Third Girl (1966)

This is a less successful crime novel (Christie tries to write about drugs and youth culture, topics that don't suit her) but we still get some good Mrs Oliver moments, such as her request to Poirot that he be the guest speaker at the "Detective Authors' Club" annual dinner, thereby confirming that she is a member of a Detection Club equivalent. Christie, by the way, was the president of the real-life Detection Club when she published this novel. This book also contains some good examples of Mrs Oliver's compassion, particularly for girls and young women, and perhaps my favourite sequence hers of all, where she briefly turns shoe-leather detective and trails a suspect across London.

Hallowe'en Party (1969)

These days, I think people mostly read this book for the seasonal vibes rather than the mystery, which is probably as it should be. The opening chapter where Mrs Oliver is helping out at her friend's children's Halloween party is lovely. The book is interesting for the scholar of Ariadne Oliver, though, because as in Dead Man's Folly she has to confront the fact that her presence might have precipitated an until-then theoretical murderer into taking practical action. Once again, Mrs Oliver summons Poirot onto the investigation, confirming that their connection remains close and strong 35 years on.

Elephants Can Remember (1972)

My overwhelming feeling about this book is that it is very sad. Its subject matter is deeply tragic — more so than the average Christie mystery — and its thematic focus on ageing and memory is melancholy, too. Mrs Oliver wrestles (as Christie probably was too, four years before her death) with feelings about being an old woman, the world having changed around her, and not being able to rely on her own memory as she once did. I don't love this novel or yearn to re-read it often, but as I looked at it again for this episode I came to see it as a fitting conclusion for a character who had spanned so much of her creator's career and become a vessel for many of her own preoccupations.

I hope you'll enjoy listening to this episode — Agatha and Ariadne — and I'll be back with you next Wednesday with our monthly reading recommendations.

Until then,

Caroline

Dear listeners,

For the final Shedunnit episode of 2025, I am asking all six of the guests who joined me for Green Penguin Book Club episodes this year to take a nostalgic look at the place the series has in their own lives. In particular, I asked them to remember what their first Green Penguin encounter was. We talked about everything from the joys of the Puffin Club to the fun of coming across unknown titles in bookshops.

As several of them pointed out in the discussions you'll hear in this new episode, the Penguin series is often an early way of discovering new titles and authors for a young reader. As long as you aren't after rare titles or first editions, secondhand Penguin paperbacks tend to be pretty easy and cheap to come by. Plus, you have the guarantee that somebody knowledgable back in the day thought the book was worth republishing, even if it isn't very well known today.

What was your first Green Penguin? Do you remember? I think mine was a loved-to-death copy of The Labours of Hercules by Agatha Christie, a short story collection I have always loved because it was among the first mysteries I ever read.

I went looking in my own Green Penguin collection to see if I had any of the books my guests named so that I could show them to you, with mixed results.

I do have The Plague Court Murders by Carter Dickson (aka John Dickson Carr), which Tom Mead named as one of his most prized Penguins:

And I also have The Big Sleep by Raymond Chandler, which Sergio Angelini talked about (even though I have — gasp! — yet to actually read it):

But otherwise I drew a blank on their specific titles! I do have some others by authors they named, though, such as this Margery Allingham, another favourite of Sergio's:

Plus this book by J.J. Connington, which I think is brilliant:

Lastly, I pulled out my slightly battered copy of The Documents in the Case by Dorothy L. Sayers and Robert Eustace, because that's going to be the subject of the next Green Penguin episode in January:

I will see you in two weeks for the start of a brand new year of Shedunnit! I think you're really going to like the first episode I've got lined up...

Until then,

Caroline
