Book cover of The Silence of the Lambs

Christine Daigle Author Of Heavy Are The Stones

From my list on books with minds as twisted as their crimes.

Why am I passionate about this?

I’ve always been fascinated by the darker corners of the human mind, such as what drives people to commit unspeakable acts and how others find the strength to face them. As both a neuropsychologist and a thriller author, I explore those questions on the page, weaving together my background in psychology with my love of twisty, character-driven stories. Books where the crimes are as twisted as the minds behind them have shaped my own writing, including my latest novel, Heavy Are the Stones. I read them not just for the suspense, but for the unsettling and raw truths they reveal about us all as humans.

Christine Daigle Why Christine loves this book

Hannibal Lecter’s silky smooth menace still chills me like no other villain on my shelf.

Silence of the Lambs taught me how to write a terrifying villain with more than enough charisma to start a devoted cult. Every reread of this book hooks me with that hypnotic voice. Hannibal’s character is so persuasive and razor-sharp, I catch myself sympathizing before the dread slams back in.

I love how Thomas Harris forces me to straddle the line between fascination and horror, then shoves me into Clarice Starling’s head for that heart-hammering showdown with Buffalo Bill.

Decades later, for me, no thriller matches its psychological intrigue. It’s a timeless classic that keeps my lights blazing and my imagination deliciously unsettled.

By Thomas Harris ,

Why should I read it?

22 authors picked The Silence of the Lambs as one of their favorite books, and they share why you should read it.

What is this book about?

As part of the search for a serial murderer nicknames "Buffalo Bill," FBI trainee Clarice Starling is given an assignment. She must visit a man confined to a high-security facility for the criminally insane and interview him.

That man, Dr. Hannibal Lecter, is a former psychiatrist with unusual tastes and an intense curiosity about the darker corners of the mind. His intimate understanding of the killer and of Clarice herself form the core of Thomas Harris' The Silence of the Lambs--an unforgettable classic of suspense fiction.

Book cover of The Alienist

David Cairns Author Of The Case of the Hydegild Sacrifice

From my list on exploring the historical, cultural, and psychological landscapes of 1800s America.

Why am I passionate about this?

Over the years, I’ve lived and worked in the US, and I find it endlessly fascinating. With its mix of cultures, regional identities, and historical tensions, it often felt like several nations merged into one, forged initially against Britain with the help of France. Living there and reading extensively about its history gave me a personal perspective on the forces shaping the nation. 

Researching the year 1865 around Abraham Lincoln’s assassination, I discovered far more than I expected, deepening my understanding of the era. I wanted to share a selection of American novels—works that influenced my thinking or mirror the historical mystery and adventure central to that period.

David Cairns Why David loves this book

Blends psychological thriller, historical fiction, and detective mystery, set in New York City in 1896.

Journalist John Schuyler Moore and psychologist Dr. Laszlo Kreizler, aided by a young Theodore Roosevelt, investigate brutal murders that shock the city. Carr’s meticulous research brings Gilded Age New York vividly to life, from opulent drawing rooms to grim tenements.

The novel explores the roots of criminal profiling and human darkness, reflecting techniques I use in my own book's character’s investigations, including incorporating real historical figures for authenticity.

10 authors picked The Alienist as one of their favorite books, and they share why you should read it.

What is this book about?

The internationally bestselling historical thriller, now a major Netflix series starring Luke Evans, Dakota Fanning and Daniel Bruhl.

Some things never change.

New York City, 1896. Hypocrisy in high places is rife, police corruption commonplace, and a brutal killer is terrorising young male prostitutes.

Unfortunately for Police Commissioner Theodore Roosevelt, the psychological profiling of murderers is a practice still in its infancy, struggling to make headway against the prejudices of those who prefer the mentally ill - and the 'alienists' who treat them - to be out of sight as well as out of mind.

But as the body count…

Christine's book list on books with minds as twisted as their crimes

Christine Daigle Why Christine loves this book

I enjoy mysteries that tie my brain in knots, and With A Vengeance had more twists than a pretzel.

Right from the start, the premise flips the genre on its head where the main character, Anna Matheson, who wishes everyone she has gathered together was dead, is also the one who must save them. I loved that Riley Sager set the entire locked-room mystery inside a moving train where every passenger is a suspect, yet somehow maybe none of them are guilty.

I spent the whole ride toggling between motives and alibis, sure I’d cracked it, only to be blindsided by another twist. Sager’s color-coded cast felt like walking Clue pieces, vivid enough that I swore I would find Mr. Plum in the Conservatory with the candlestick. But I certainly didn’t make the correct guess, and there’s nothing I love in a book more than a surprise ending!

The way…

Christine's book list on books with minds as twisted as their crimes

Christine Daigle Why Christine loves this book

Eriq La Salle is best known for his role as Dr. Peter Benton on the hit TV show ER, but Laws of Depravity shows that he’s a magnificent writer as well as a prolific actor.

I have read a lot of crime fiction, yet Laws of Depravity stopped me cold and made me question whether “the killing of devils is a condemnable act.” Growing up a preacher’s kid, I’m fascinated by the ways people use religion as an explanation or shield for both wonderful and terrible acts.

Lasalle doesn’t shy away from looking at the darker side, and that made me brave enough to take a closer look in my own work. La Salle has delivered a highly character-driven book that profiles the detectives and civilians as much as the killer while still maintaining that thrilling pace. Every morally gray twist felt earned, and the surprises kept coming right up…

30 years. 36 priests butchered. His bloodiest masterpiece is yet to come.

Every ten years, for the past 30 years, a dozen clergymen are killed, brutally murdered in twisted scenes emulating the deaths of Jesus and his disciples. It is the work of a serial killer known as "The Martyr Maker." And in 2011, he set his mark on New York City.…

Bryony Best Author Of Bloodshed in the Hampshire Cabin

From my list on thrillers that aren't predictable or snail-paced.

Why am I passionate about this?

I have a wealth of knowledge and experience for living through tragic situations from my young adult life. I have overcome a traumatic childhood, alcoholism, drug addiction, and mental health. I find psychology fascinating; I have personally had many attempts by others to take my life. I have survived violent attacks, stalkers, and abuse. I love thriller books that have psychology embedded alongside many life lessons.

Bryony Best Why Bryony loves this book

This book had me hooked from the very beginning, it is exciting and shocking.

Many books can have slower chapters than others but there were no slow chapters in this book. The ending was not super predictable like some thriller books can be, and the characters were rich with great background stories.

I devoured this book and if you read one thriller book this year then make sure it is this one. The MC is a detective who is being taunted by a serial killer and the story felt current and not outdated. I am a fan of Criminal Minds and Psychology and if you are too then give this book a read.

Book cover of Don't Talk to Strangers

Christopher Swann Author Of Never Back Down

From my list on crime fiction featuring powerful female characters.

Why am I passionate about this?

I love crime fiction, but the genre can be very much a boys’ club where women are sometimes reduced to femmes fatales or victims who need to be saved. When I look at my bookshelves, I realize how many of the books I’ve read are written by men about men. There’s nothing wrong with stories about men, but I have a lot of strong women in my life, and I’ve learned so much from listening to their perspectives. As a writer, I like pushing myself to try and create strong female characters who find themselves ensnared in a crime and have to figure their way out.

Christopher Swann Why Christopher loves this book

Amanda Kyle Williams quit school at sixteen, was diagnosed with dyslexia at twenty-two, and read her first book at twenty-three. She overcame addiction and wrote while working odd jobs, becoming a best-seller with her Keye Street series.

My wife heard Amanda speak at a dyslexia conference and told her about her husband who wanted to write books; later when I met Amanda at the Decatur Book Festival, she smiled and said, “Oh, yeah, you’re the writer.”

I love her protagonist Keye, a private investigator in Atlanta and former FBI profiler. She’s funny and gutsy and wrestles with her own demons. Don’t Talk to Strangers, the third in the series, is as good as the first two. Amanda died of cancer in 2018, but she left behind a tremendously inspiring legacy in both Keye and her own incredible story.

Book cover of Rain Will Come

Elle Mitchell Author Of Another Elizabeth

From my list on dark fiction serial killer.

Why am I passionate about this?

My interest in serial killers began when I was a teen watching horror movies with my mom. I learned all I could about them—even became a horror special-effects makeup artist. Eventually, I had to quit due to my connective tissue disorder (Hypermobile Ehlers-Danlos Syndrome). It put me on a path of writing. I love digging into the darker side of humanity—murder or mental illness. The story of a serial killer who could challenge the reader to see disability in a new light came to me, and I had to write her story, if not just so I could dive into the psyche of another serial killer.

Elle's book list on dark fiction serial killer

Elle Mitchell Why Elle loves this book

The biggest strength of this book is a large spoiler, which is a shame. I’d love to gush about it. You (should you choose to read it) get to learn about it as the work unfolds, though. For that, I’m jealous. Who doesn’t love to enjoy something so fun for the first time? The choice of victims and the reason for the kills makes the serial killer so compelling I rooted for the detective to always be one step behind. I loved him, don’t get me wrong. He is flawed and damaged, and I wanted him to succeed eventually. Thomas Holgate makes it easy to do that—want them both to “win”—as both have a point-of-view. The book was fun, interesting, and just a little brutal.

Why am I passionate about this?

A few years ago (okay, decades, really), I left the seminary to become a young evangelist, then a denominational youth director, a college public relations director, a guest lecturer, an adjunct professor, and a pastor in three churches. And now I write. 

I was in Israel when terrorists landed on the beach, intending to attack a hotel filled with travelers. Maybe my hotel. Their mission was thwarted, but I started thinking about terrorists attacking my homeland. And then it happened. Over the years, I’ve studied issues involving terrorism and even graduated from the Seattle FBI Citizens Academy. This is why I write inspirational thrillers today.

Book one in the Lacey Flint series, Now You See Me, got me hooked on the author and British mysteries. The writing style is evocative and deeply atmospheric, reminding me of gothic novels with a modern aspect.

I liked Lacey as a character, but what I found most compelling was the plot, which was a literary spider web. Although it was too graphic for my taste in places, the story was riveting enough to keep me engrossed until the very last page. I could barely keep track of all the twists and turns. By the time I finished reading, I had applauded the mind that could come up with such a complex story.
