The best psychological thrillers balance suspense with insight into motive, obsession, and the unsettling psychology behind violent crime.
If you’re fascinated by dark psychology, mind games, and stories that get inside a killer’s head, these psychological thriller picks will keep you hooked until the final page.
Here are some of the most chilling serial killer thrillers and psychological suspense novels to add to your reading list:
Blood Sugar
by Sascha Rothchild

“I could just kill you right now!” It’s something we’ve all thought at one time or another. But Ruby has actually acted on it. Three times, to be exact.
Though she may be a murderer, Ruby is not a sociopath. She is an animal-loving therapist with a thriving practice. “She’s felt empathy and sympathy. She built long-lasting friendships and relationships and adores her husband, Jason. However, the homicide detectives at Miami Beach PD doubt her happy marriage. When we meet Ruby, police are interrogating her, accusing her of Jason’s murder. Which, ironically, is one murder that she did not commit, though her vicious mother-in-law and a scandal-obsessed public believe differently. As she undergoes questioning, Ruby’s mind races back to all the details of her life that led her to this exact moment, and to the three dead bodies in her wake. Because though she may not have killed her husband, Ruby certainly isn’t innocent.
Alternating between Ruby’s memories of her past crimes and her present-day fight to clear her name, Blood Sugar is a twisty, clever debut with an unforgettable protagonist who you can’t help but root for—an addicting mixture of sour and sweet.

How to Kill Your Family
by Bella Mackie
I have killed several people (some brutally, others calmly) and yet I currently languish in jail for a murder I did not commit.
When I think about what I actually did, I feel somewhat sad that nobody will ever know about the complex operation that I undertook. Getting away with it is highly preferable, of course, but perhaps when I’m long gone, someone will open an old safe and find this confession. The public would reel. After all, almost nobody else in the world can possibly understand how someone, by the tender age of 28, can have calmly killed six members of her family. And then happily got on with the rest of her life, never to regret a thing.
When Grace Bernard discovers her absentee millionaire father has rejected her dying mother’s pleas for help, she vows revenge, and sets about to kill every member of his family. Readers have a front row seat as Grace picks off the family one by one. The result is as and gruesome as it is entertaining in this wickedly dark romp about class, family, love… and murder.
But then Grace is imprisoned for a murder she didn’t commit.
Outrageously funny, compulsive and subversive, perfect for fans of Killing Eve and My Sister, the Serial Killer.

The Kind Worth Killing
by Peter Swanson

In a tantalizing set-up reminiscent of Patricia Highsmith’s classic Strangers on a Train… On a night flight from London to Boston, Ted Severson meets the stunning and mysterious Lily Kintner. Sharing one too many martinis, the strangers begin to play a game of truth, revealing very intimate details about themselves. Ted talks about his marriage that’s going stale and his wife Miranda, who he’s sure is cheating on him. Ted and his wife were a mismatch from the start—he the rich businessman, she the artistic free spirit—a contrast that once inflamed their passion, but has now become a cliché.
But their game turns a little darker when Ted jokes that he could kill Miranda for what she’s done. Lily, without missing a beat, says calmly, “I’d like to help.” After all, some people are the kind worth killing, like a lying, stinking, cheating spouse. . . .
Back in Boston, Ted and Lily’s twisted bond grows stronger as they begin to plot Miranda’s demise. But there are a few things about Lily’s past that she hasn’t shared with Ted, namely her experience in the art and craft of murder, a journey that began in her very precocious youth.
Suddenly these co-conspirators are embroiled in a chilling game of cat-and-mouse, one they both cannot survive . . . with a shrewd and very determined detective on their tail.

He may not be the brightest or the most interesting man in town, but nevertheless, he’s the kind of officer you’re happy to have keeping your streets safe. The sort of man you might even wish your daughter would end up with someday.
But behind the platitudes and glad-handing lurks a monster the likes of which few have seen. An urge that has already claimed multiple lives, and cost Lou his brother Mike, a self-sacrificing construction worker who fell to his death on the job in what was anything but an accident.
