Book cover of Undertaking Irene

KJ Sweeney Author Of The Body at Back Beach

From my list on adventures of female amateur sleuths.

Why am I passionate about this?

I’ve loved murder mysteries since I first discovered the genre. As a child, I loved watching Morse, Miss Marple, and other detectives as they got to the bottom of whodunit. I was hooked. It wasn’t long before I started to read books starring these detectives. I really love the way that female amateur detectives often have far more ideas of what’s going on and why things have happened than the men who populate the books. What woman can’t resist reading about another woman who just gets to the bottom of it all? I know I can’t, but these books are some of the very best in the genre.

KJ Sweeney Why KJ loves this book

I can’t resist a book that can make me laugh and has a great storyline. This murder mystery has books in bucketfuls. I love the way that humor is woven into the story.

I think that the thing that really makes this story such a great read is the different characters that fill the pages. I fell in love with the main character, Jane, and her love interest, the padre, and I, of course, completely loved her dog, Sexy Beast.

What is this book about?

Jane Delaney does things her paying customers can’t do, don’t want to do, don’t want to be seen doing, can’t bring themselves to do, and/or don’t want it to be known they’d paid someone to do. To dead people.

Life gets complicated for Jane and her Death Diva business when she’s hired to liberate a gaudy mermaid brooch from the corpse during a wake—on behalf of the rightful owner, supposedly. Well, a girl’s got to make a living, and this assignment pays better than scattering ashes, placing flowers on graves, or bawling her eyes out as a hired mourner. Unfortunately…

Book cover of Picnic at Hanging Rock

Debbie Young Author Of Dastardly Deeds at St Bride's

From my list on fiction set in boarding schools.

Why am I passionate about this?

As the author of comedy cosy mystery novels, including a series set in an eccentric boarding school for girls, I’m always attracted by the notion of closed, clearly-defined worlds as colourful settings for stories of crimes and misdemeanours. Having worked for 13 years in a girls’ boarding school, where I loved being part of its lively and spirited community, I am very familiar with the quirks and foibles, as well as the practicalities, of boarding school life, and I really enjoy reading other people’s impressions and interpretations of boarding schools of all kinds. 

Debbie's book list on fiction set in boarding schools

Debbie Young Why Debbie loves this book

Finally, a serious, sombre book, and a modern classic. Set at a strict boarding school for girls, Appleyard College in Australia, it tells the story of an ill-fated outing to a local beauty spot at which a teacher and two pupils go missing. Lindsay brilliantly sets up the mystery with all kinds of backstories, and (plot spoiler alert) it’s never truly resolved, but the haunting story lingers with the reader long after they’ve finished the book. This has also been made into a film, but as always, it’s worth reading the original story – Lindsay’s writing is as evocative as any film.

**A BBC BETWEEN THE COVERS BIG JUBILEE READ PICK**

'A sinister tale' Guardian

The classic, atmospheric Australian thriller about the mysterious disappearance of a group of young girls.

Book cover of The Troubled Man

Fay Sampson Author Of In the Blood

From my list on crime novels that have a rich dimension.

Why am I passionate about this?

I don’t warm to crime novels where the only point is to find whodunnit. Those that resonate with me are the ones that have an extra dimension. It may be taking me into a world I am unfamiliar with, like bell-ringing or a theatre troupe. Or it could be a richly-evoked setting, like Donna Fletcher Crow’s Celtic Christian background. Or a character whose very flaws make them more gripping, such as Rebus or Wallender. I want to come away feeling enriched and not just pleased that I guessed that it was the butler with the candlestick.

Fay's book list on crime novels that have a rich dimension

Fay Sampson Why Fay loves this book

Mankell’s troubled hero, Kurt Wallender, hits new depths in this final novel. Things have not been well. His handgun left on the seat of his car was to be picked up by a child. Past conversations with his artist father, who paints the same landscape 7000 times while his memory deteriorates. Wallender now has to face the realization that he, too, is losing his memory. I felt for him on this difficult journey.

But there is still a last case to be solved. The father of his daughter’s fiancé goes missing on his morning walk. Dark secrets from Sweden’s Cold War past threaten to resurface. Wallender has to battle with deteriorating health to solve the mystery, fearing the truth may not be welcome. For me, his integrity shines through.

Every morning Hakan von Enke takes a walk in the forest near his apartment in Stockholm. However, one winter's day he fails to come home. It seems that the retired naval officer has vanished without trace.

Book cover of All the Missing Girls

Ellen Won Steil Author Of Fortune

From my list on satisfying your dark, suspense craving.

Why am I passionate about this?

I’ve always loved dark stories. There is something especially human about being lured by that part of us we bury. How secret desires and thoughts get teased out in ways we don’t really experience in real life. Which is why I write suspense novels. Sometimes you just want to go there! Here are some books that I find hit that fix.

Ellen's book list on satisfying your dark, suspense craving

Ellen Won Steil Why Ellen loves this book

No matter how much you may love a certain genre, you can inevitably fall into a reading slump. Too much of a good thing, right?

I will begrudgingly admit, the “missing” or “murdered girl” trope can sometimes get a bit dull without a new touch. Which is why when I came across Megan Miranda’s adult debut told entirely in reverse (from Day 15 to Day 1) was I ever floored with delight!

How absolute genius is it to take a twisty, shocking story about the disappearance of two girls, decades apart but give it to reader backwards? I found myself deeply engrossed not only in the propulsive story but intrigued by the unique way I had to process the timeline.

Book cover of Missing, Presumed

Sara Davis Author Of The Scapegoat

From my list on detective novels that keep you page turning.

Why am I passionate about this?

I love reading mysteries, ever since I started back in junior high with Hercule Poirot, I have loved an atmospheric murder and ensuing investigation. As I’ve gotten older and started writing my own books, though, I’ve gotten pickier about what kinds of detective novels I can stick with—I now require that they also be excellent on the sentence level, which isn’t always easy to find. I also find that I gravitate towards books that have pockets of dry humor from time to time and a unique investigator.

Sara's book list on detective novels that keep you page turning

Sara Davis Why Sara loves this book

I loved this book (the first in a trilogy) mostly because of its main character, Detective Inspector Manon Bradshaw. She’s investigating the disappearance of a beautiful graduate student at Cambridge, but the book is full of wry humor about Manon’s own predicament, which is that she is single and unhappily internet-dating.

She also loves snacks; there are lots of good snacks in the book. All three of the books in the series are really, really gripping and good. Steiner (who died in 2022) is a genius at writing about the feelings between people.

Book cover of The Silver Serpent

Jon Glass Author Of Worcester Glendenis, Kid Detective

From my list on middle grade detective fiction.

Why am I passionate about this?

As a child I loved reading detective stories, and I still retain strong memories of Tintin and Sherlock Holmes, after which I graduated to Agatha Christie. As an adult my tastes changed and I lost interest in mysteries (with the exception of Edgar Alan Poe). However recently my interests have reversed, partly because I became a grandfather, and partly for the reason that I teach ethics to primary school children, as a volunteer. So it’s possible that Worcester Glendenis is a re-incarnation of me, but as the 12-year-old I wish I had been (as far as my memory can be relied upon to go back 60 years): more emotionally mature and more extrovert.

Jon's book list on middle grade detective fiction

Jon Glass Why Jon loves this book

This book is very arty by which I mean it introduces the young reader to the world of art and art galleries. There is also a strong dose of spy-type intrigues.

A very snooty older man gets satirised for his arrogance, which I think is a nice twist for the reader and a good change from the bossy types who often appear. The father-daughter relationship is well done.

Book cover of The Searcher

Aime Austin Author Of Judged

From my list on crime fiction that made me love the human race.

Why am I passionate about this?

I’m agnostic to book genre. If I see it, I will try it. I read all over the place. I just finished a book on online dating and race, the buzzy fiction of the moment, and a self-help book. There are two genre’s that are my absolute favorites, though, women’s fiction, and police procedurals. I’ve read Elizabeth George, Julia Spencer Fleming, Michael Connelly, and Tana French since they started publishing. While I enjoy the whodunit nature of the books, my favorite parts are those quiet moments of pure, unfettered relations between people who care for each other in an otherwise chaotic world. It’s what I write and what I read.

Aime's book list on crime fiction that made me love the human race

Aime Austin Why Aime loves this book

Irish author Tana French is known for her Dublin Murder Squad series and is what some call a literary crime writer.

The Searcher, a standalone novel, explores themes of restorative justice. Chicago cop Cal Hooper retires to rural Ireland where he undertakes the renovation of a dilapidated cottage. While he toils, he’s joined by a nearly silent teen Trey.

It’s another book where an adult and child don’t realize they need each other, but so quietly and beautifully help heal each other’s wounds.

This was my absolute favorite book in this author’s canon. It’s not perfect, but it’s perfectly imperfect.

Book cover of The Story She Left Behind

Linda Rosen Author Of Abandoning the Script

From my list on novels that circle around long-held family secrets.

Why am I passionate about this?

I’ve heard many stories from friends who, as adults, discovered that the person they always believed to be their mother or father was not, and saw what it did to their sense of self. I became fascinated by the how and why a family would perpetuate such a lie, and it made me wonder about the difference between a secret and a lie, and if there is one. This set me off writing novels about family secrets, and reading many more. I enjoy exploring what such devastating news does to a person, and to the entire family, once the secret is discovered.

Linda Rosen Why Linda loves this book

I was drawn in immediately by the prose, tone, and atmosphere, not to mention the mystery.

I wanted to just sit and read this book and forget everything else I had to do. How can you not love a story about a legendary book, a lost mother, and a daughter's search for both of them?

And I loved the settings: London, England’s Lake District, and South Carolina’s Low Country. They’re so vivid, I felt as if I was there with the characters.

Paula Charles Author Of Hammers And Homicide

From my list on cozy mysteries with strong family ties.

Why am I passionate about this?

I’m a cozy mystery writer and reader who loves to suss out family dynamics in the books I’m devouring. My love of genealogy and turning family stories into fiction played a large role while writing my first book, Hammers and Homicide. Wherever my husband and I travel, we search for ancestors in ancient cemeteries and try to find out more about their stories. You’ll find a few of them between the pages of my books. I hope you’ll enjoy these books, all featuring some level of family ties, as much as I did!

I can’t even tell you how much I love Aunt Ginny in Libby Klein’s Poppy McAllister Mystery series! She is an absolute hoot. While I love the whole series, the first introduction to Aunt Ginny in this book remains my favorite. 

Poppy is newly widowed and a grief-stricken disaster when she receives an invitation to her high school reunion. She heads home to Cape May and her eccentric Great Aunt Ginny’s house. As they do in cozy mysteries, a murder happens, and Poppy and Aunt Ginny are on the case.

Poppy and her aunt’s relationship, paired with Aunt Ginny’s crazy antics, always leaves me wiping tears of mirth out of my eyes. Such a fun read!

Book cover of Bluebird, Bluebird

LeRenyae Watkins Author Of Contempt

From my list on crime novels where the system is the real villain.

Why am I passionate about this?

I write what I call civic noir, crime fiction where the real antagonist isn’t a person but an institution: a courthouse, a precinct, a city hall that already knows how the story ends. I’m drawn to these books because the most frightening thing in them is never the gun; it’s the machinery, the procedure, the quiet way a system decides who’s guilty before anyone enters a courtroom. As a writer, I’m less interested in the villain than in the architecture that produces him. These five novels taught me how to make a building feel dangerous, and how to keep ordinary people from disappearing into the gears.

LeRenyae's book list on crime novels where the system is the real villain

LeRenyae Watkins Why LeRenyae loves this book

Locke does the thing I’m always chasing. 

She makes the law itself the source of suspense. Her Texas Ranger, Darren Mathews, carries a badge that protects him and endangers him in the same gesture, and every door he opens with it might be the one that gets him killed. I love that she refuses easy heroes. Everyone in that little town off Highway 59 is wired into the same old order, and justice has to be smuggled out past it. 

She taught me a murder mystery can be a way of asking who the system was built to serve, and that the quietest scene is often the most dangerous one.
