Book cover of Devil in a Blue Dress

Ashley Clifton Author Of Twice The Trouble

From my list on literary novels masquerading as crime novels.

Why am I passionate about this?

Flannery O’Connor once said that all fiction is ultimately about the “mystery of personality.” I agree. In fact, I have always suspected that all good novels, genre-based or otherwise, are secretly mystery novels, if only in the psychological sense. Conversely, many so-called genre novels have just as much depth, insight, and realism as any literary work. I have read a lot of genre and literary fiction in my time, and I have long been fascinated by works that blur the line between the two. My favorite kind of book is one that feels like a genre novel (that is, it has a great plot) but also has the depth and vividness of a literary novel.

Ashley's book list on literary novels masquerading as crime novels

Ashley Clifton Why did Ashley love this book?

What I really love about this novel is the voice of the main character, Ezekial “Easy” Rollins. Easy is not your typical P.I. A recently fired machinist in post-war Los Angeles, he’s just a guy trying to pay his bills. But he’s also a black man from the South trying to survive in a white, west-coast world. When a white gangster hires him to find a missing girl, Easy senses that he’s in extreme danger, but he has no choice but to take the job.

Told in the first-person, this book captures all of Easy’s doubt, dread, and defiance as he unravels the mystery.

What is this book about?

Devil in a Blue Dress honors the tradition of the classic American detective novel by bestowing on it a vivid social canvas and the freshest new voice in crime writing in years, mixing the hard-boiled poetry of Raymond Chandler with the racial realism of Richard Wright to explosive effect.


Book cover of The Cuckoo's Calling

Maurice Holloway Author Of Steal a Diamond

From my list on detective books with the most memorable protagonist.

Why am I passionate about this?

I have a passion for writing, and whenever I can, I try to help new writers improve their expertise so that one day they’ll complete their first book. My first book, born from a few-hundred-word short story at my writing group, turned into a three-book thriller series called FAVOURS. Since then, I’ve branched out by publishing a rom/com, a humorous ghost story as well as a standalone thriller. Agatha Christie published her first book as the result of a dare, which proves you can do it if you really want to.

Maurice's book list on detective books with the most memorable protagonist

Maurice Holloway Why did Maurice love this book?

As a multi-genre author, I was interested to see how the creator of a world-famous boy wizard was going to change her name and turn her hand to crime writing. I relished the result: the first outing for a new private investigator, a character called Cormoran Strike.

Known simply as Strike, he is a P.I. with a handicap (aren’t they all?). Not just the common ones; excessive drinking, difficult relationships, and so on, Strike lost half his right leg whilst serving in Afghanistan. Retiring from service, the ex-MP becomes a private investigator. He has few clients, no money, and is scruffy and unkempt because he sleeps in his office. But he does have a motto, "Do the job and do it well."

In social relationships, Strike isn’t a likable character; demanding and sometimes just plain rude. He has lost his last assistant. I warmed to him the more his traits…

Book cover of Vanished

Rebecca Hartt Author Of Returning to Eden

From my list on Christian military romance about overcoming fear.

Why am I passionate about this?

My passion and expertise for writing Christian Military Romance stems from the fact that I was a military wife—twice. My first husband, an Army officer died eight years into our marriage. I then married a petty officer in the Navy—all this on top of growing up all over the world as my father worked in the foreign service. As someone who views the world through the lens of faith and who relies on God to overcome hardship, I'm convinced that the elite warriors who protect us and who fight giants on our behalf must also rely on faith. Tie all those elements together, and, voilá, you have a Rebecca Hartt Acts of Valor book!

Rebecca Hartt Why did Rebecca love this book?

Two sentences into Vanished, and I was hooked!

I have to admit, I’m a tough sell when it comes to the genre I write. But Ms. Hannon is an excellent writer. She never “tells”; she “shows”. Her characters are motivated by their faith, just like I am. While Irene Hannon does not feature military heroes in her stories, her police detectives display the same level of discipline and willingness to take on danger.

She has done her research and portrays realistic investigations. Her heroine is a mature, complex individual—someone I would like to meet and befriend. And the romance that blossoms between Moira and Cal is natural and touching.

This is also a second-chance romance, which gets me every time. The only way it could be better would be to throw a kid into the story.

Reporter Moira Harrisons is lost. In the dark. In a thunderstorm. When a confusing detour places her on a rural, wooded road, she's startled by the sudden appearance of a lone figure caught in the beam of her headlights. Though Moira jams on her brakes, the car careens across the wet pavement--and the solid thump against the side of the vehicle tells her she hit the person before she crashes into a tree on the far side of the road.

A dazed Moira is relieved when a man opens her door, tells her he saw everything, and promises to call…


Book cover of Case Histories

Jenny Twist Author Of A Gift for Murder: A Tommy Ross mystery

From my list on crime fiction with memorable plots and characters.

Why am I passionate about this?

I’ve been reading crime fiction all my life. I love following the detective sifting through the evidence—the clues, the false trails, and the eventual denouement. It was a crime fiction book that made me realise that history is not fixed but is, in fact, detective work. It changes as more evidence is discovered or a new interpretation is accepted. That book made me decide to take history as my subject at university and I spent six deliriously happy years examining evidence, evaluating it, and, reaching conclusions. Amongst my case studies were the princes in the tower, the gunpowder plot, and witchcraft. Happy days!

Jenny's book list on crime fiction with memorable plots and characters

Jenny Twist Why did Jenny love this book?

All Kate Atkinson’s books are beautifully written, with wicked observation, but what I love about them most is the reality of her characters. 

None is more addictive than her detective, Jackson Brodie. I chose this book, not just because it’s the first in the series, but because it moved me so much. I have read it over and over again and each time it makes me cry. I want to take Theo, who still yearns for his murdered daughter, into my arms and comfort him. 

Like me, you will want to know what happened to the little girl who disappeared from her own garden one night and what possessed one woman to kill her husband with an axe. 

Through it all runs a subtle humour, which will make you laugh out loud. 

It is, for me, the perfect book.

Book cover of Why Kings Confess

Karen Hanson Stuyck Author Of Death of an Unfortunate Woman

From my list on strong women solving mysteries in Great Britain.

Why am I passionate about this?

I grew up loving stories set in the 1800s. I read Little Women six times, determined to become a writer just like Jo March. Eventually, I became one, writing everything from newspaper articles to medical brochures, short stories, and nine mystery novels. I set my latest book in 1819 Regency England. The myriad rules governing every aspect of proper behavior for “gently bred women” meant that any female refusing to conform faced scandal and ostracism from society. Any woman who managed to forge a life of her own design had to be strong, determined, and feisty—just the kind of female I want to read and write about.

Karen's book list on strong women solving mysteries in Great Britain

Karen Hanson Stuyck Why did Karen love this book?

Unlike my other book choices, Why Kings Confess has a male protagonist, Sebastian St. Cyr. In my opinion, a very good historical mystery series got even better when Sebastian married Hero Jarvis, the brilliant and outspoken daughter of Sebastian’s mortal enemy, Lord Jarvis, a ruthless advisor to the crown. Hero writes searing investigative articles on societal injustice and, despite being heavily pregnant, participates actively in Sebastian’s work. In this book they investigate the brutal death of a man who was part of a secret delegation sent by Napoleon to determine the possibility of peace with Britain. The author is a historian who manages to seamlessly incorporate a lot of fascinating information about Regency England.

What is this book about?

The gruesome murder of a young French physician draws aristocratic investigator Sebastian St. Cyr and his pregnant wife, Hero, into a dangerous, decades-old mystery as a wrenching piece of Sebastian’s past puts him to the ultimate test.

Regency England, January 1813: When a badly injured Frenchwoman is found beside the mutilated body of Dr. Damion Pelletan in one of London’s worst slums, Sebastian finds himself caught in a high-stakes tangle of murder and revenge. Although the woman, Alexi Sauvage, has no memory of the attack, Sebastian knows her all too well from an incident in his past—an act of wartime…


Book cover of March Violets

David Miller Author Of Solved: How the World's Great Cities Are Fixing the Climate Crisis

From my list on books that evoke a place and take you there.

Why am I passionate about this?

I love cities, and as a former Mayor, I understand their vibrant complexity. Like all of us, I am deeply worried about planetary breakdown, but unlike most, I’ve had the privilege of seeing firsthand the great work that leading mayors are undertaking globally to address the climate crisis. It's my belief that if more of us knew what is happening in some cities, and therefore what is possible in all, we would not only see that it is possible to avoid climate breakdown but fuelled by that hope, we would demand change from those we elect. You can hear more in the podcast I lead, Cities 1.5, or read more in my occasional newsletter on substack.

David Miller Why did David love this book?

This is a noir-style detective novel set in Berlin in the 1930s. The protagonist, private detective Bernie Gunther, is a disaffected police officer who has left its service because of the Nazi takeover of public institutions - and all the corruption and brutality that come with it.

I loved the book, the first of a trilogy, and I immediately read the next two because of its main character, Berlin. I have been visiting Berlin for 40 years and am fascinated by its seedy, gritty, and tragic history and its resilience as a city. Berlin Noir evokes the Berlin of the 1930s in a way that only fiction can do. Brilliant.

Glen Hirshberg Author Of Infinity Dreams

From my list on loners whose passions lure them to other people.

Why am I passionate about this?

All my life, I’ve been fascinated by interest-driven people and the subcultures they discover or form around themselves. Though my writing ranges from mainstream literary work to music criticism to speculative fiction in many different flavors, I’m best known for what one longtime reader referred to as my “oddly personable brand of horror.” Call them people-and-their-ghosts stories. I’ve written six novels and four collections, which have earned me the Shirley Jackson and International Horror Guild Awards, among other honors. I’ve also taught writing at the graduate, university, and secondary level for more than 25 years.

Glen's book list on loners whose passions lure them to other people

Glen Hirshberg Why did Glen love this book?

Really, almost anything in the Nero Wolfe/Archie Goodwin series would fit here. A lazy, blustering, brilliant recluse, Nero Wolfe is perpetually badgered, kicking and grumbling, back toward humanity either by his passions—American cuisine, beer, books, orchids—or by Archie, his leg-man/lacky/surrogate son. I picked this specific novel because it involves a murder amid a gathering of world-class chefs; the cooking banter alone is worth the price of admission (which will be cheap; how and why have these books somehow fallen off our collective cultural radar??). None of Nero’s adventures among his fellow human beings make him want to venture out of the fortress he has made for himself inside his Manhattan brownstone. But they’ll make you want to hole up in his company. The man himself thinks he just wants to be left alone with his interests and comforts. But what he creates and relies on to sustain him feels pretty…

Book cover of Some Buried Caesar

Chuck Greaves Author Of The Chimera Club

From my list on crime fiction with a droll sense of humor.

Why am I passionate about this?

I’ve been a crime-fiction fanatic since devouring my big sister’s Nancy Drew mysteries as a pre-teen in 1960s Long Island. They proved a gateway drug to Sherlock Holmes, Nero Wolfe, and Phillip Marlowe, and eventually, after 25 years as an L.A. trial lawyer (with a client list that included Richard Pryor), to my own debut novel, Hush Money, in 2012. I’ve just published The Chimera Club, my seventh novel and the fourth installment in my award-winning Jack MacTaggart series of legal mysteries, and I’m delighted to share my views on crime fiction, and humor, with like-minded readers.  You can learn more about me, and about Jack, by visiting my website.

Chuck Greaves Why did Chuck love this book?

Back in 2012, I had the honor of being a luncheon speaker at New York’s annual “Black Orchid Weekend” gathering of fans – and I mean fanatics – of Rex Stout’s iconic Nero Wolfe detective novels.  I was among my tribe, having cut my teeth on the Wolfe canon as a nerdy teenager to whom Stout’s books were a revelation: compact tales of crime and punishment starring a corpulent, agoraphobic gourmand and orchid fancier whose formidable (and unabashedly Sherlockian) powers of deduction were wielded from behind a desk in his brownstone on West 35th Street with the aid of a two-fisted Boswell named Archie Goodwin. While the yarns themselves are feasts, it’s Archie’s decidedly arch humor that provides the special sauce. Forced to choose, I’ll recommend Some Buried Caesar, Stout’s sixth Wolfe installment (of 33 novels and 39 novellas), originally published in 1939. It finds Wolfe in unfamiliar territory,…

Book cover of Gobbelino London & a Scourge of Pleasantries

Jinn Nelson Author Of Traveler

From my list on underrated humorous fantasy with happy endings.

Why am I passionate about this?

As a fantasy writer, I love to play with possibilities and invent new words for our experiences. I find that humorous fantasy is especially powerful in this regard because it pairs possibilities with absurdity, coming at reality sideways or backwards, putting everyday life into a new and more interesting light. Humor has the unique ability to transcend genres, from thrillers to cozy mysteries. It helps you process difficult emotions, or lift your spirits when the world feels a little too dark. These are some of my favorites within this category, and they all happen to be the first books in a series (you’re welcome). I hope you enjoy them as much as I do!

Jinn Nelson Why did Jinn love this book?

I haven’t found many fantasy books with a talking cat as a lead character, much less as a private investigator, so I was excited to read this one.

Gobbelino and his human Callum run a detective agency; they’re hired to find an evil tome of power that is making a mess of reality.

The descriptions of chaos from Gobbelino’s perspective are especially imaginative; I saw scenes in my mind like a mashup of live action and animation, which was really fun.

Callum and Gobbs have a strong dynamic as partners, aloof yet deeply loyal to each other, which is a strong emotional theme that resonates throughout their capers.

Why am I passionate about this?

As a writer of gay mystery, I try to read as widely as I can—both to learn from writers who have gone before me and for the pleasure of the books themselves. I’m always thrilled when I find writers like the ones I’ve shared in this list: people who think deeply and carefully about the complexities (and, occasionally, the agonies) of being a gay man, while, at the same time, weaving in the suspense and puzzles inherent in mysteries.
