Peter Swanson's 'Eight Perfect Murders' plays with this in a literary way. The narrator, a bookseller, is contacted by an FBI agent about a series of murders that mimic famous ones from crime novels. The timeline alternates between the present investigation and the narrator's past, specifically his relationship with a mysterious woman years ago. The 'crime' being revealed isn't just the current murders, but the truth about that past relationship, which is itself a kind of crime. The two timelines are mirrors, each reflecting and explaining the darkness in the other. It's a slow, creepy burn where the past timeline feels just as immediate and threatening as the present.
A lot of people are recommending books where the alternation is between two clear time periods. What about ones that are more fluid, like 'Cloud Atlas'? It's not a strict thriller, but the nested, chronologically跳跃 narratives eventually reveal a kind of civilizational crime that repeats across epochs. The 'reveal' is the pattern itself, seen only when you hold all the timelines in your mind.
Want something deeply unsettling and ambiguous? 'Drive Your Plow Over the Bones of the Dead' by Olga Tokarczuk. The protagonist, Janina, recounts events surrounding a series of deaths in a remote Polish village. Her narration constantly dips into the past—her childhood, her work, her philosophical musings—and the timeline is deliberately disjointed. The 'crime' and its possible perpetrator are revealed through this prism of memory, astrology, and animal rights activism. The alternation isn't a clean structural device; it's a reflection of a mind that sees connections across time that others miss. You're never sure if you're reading a thriller, a manifesto, or a fairy tale, and that's the point.
Good list. I'd add 'The Secret History' by Donna Tartt. While not a traditional thriller, the central 'crime' is revealed in the opening pages, and the entire book is essentially one long flashback/alternating timeline showing how a group of classics students got to that point. The tension comes from knowing the what but slowly, deliciously uncovering the why and how through memories and shifting perspectives. The past timeline is the real story, and the present timeline is just the tragic aftermath you're constantly moving toward.
Ha, this is my favorite trope. It's like the narrative equivalent of a detective shaking a snow globe and watching all the pieces settle into a new pattern.

Esmerelda Sleuth: The Other Side of the Mirror (Book 1)
Meet Esmerelda Sleuth. Sleuth is her name and investigating is her game. (Paranormal Investigating, that is.)
Esmerelda makes a good living as an investigator in a rather progressive firm. She lives a stable and sensible life until she meets Lance; an old money "hottie" who works for a real estate firm next to her building. After accepting an invitation for a weekend getaway party, she quickly discovers that Lance has a secret. He is wealthy. That part is true. And, yes, he's procured a job as a realtor in the building next door. His secret is that he belongs to an underground society of humans who didn't abandon their connection to magic centuries ago when religion declared it evil and he has traveled through time specifically to find her and bring her back to his time to marry him. If that isn't enough of a far fetched tale to absorb, he informs her that she was born in his time to a family belonging to that same secret society and was promised in marriage to him as an infant. When enemies who didn't want to see the union of families take place made attempts on her life, her parents sent her into the future and erased her memories of them as a precaution.
Possessing virtually no belief in magic, ghosts, psychics, time travel, etc., it takes some doing on Lance's part to convince her to believe his story and go back with him. When she does, the lies, deceit and attempts on her life start all over again. Will she escape emotionally and physically unscathed?

On her unconscious bed, her husband gave the order to abort her child. Their child. Driven by lust and desperation for power, Killian Powell framed Rose Webster just to divorce her and marry her twin. At what price? To easily buy his way into her family's corporation. Rose had the evidence to expose her husband's true face to the world and tear him down. But of what use was it when her vicious parents threatened to stop the treatment of her sick daughter if she dared release the evidence? Like always, they cared more about what they stood to gain from a traitor who stabbed their daughter—a man they once despised when he was nothing. As much as Rose couldn't trade the life of her daughter, she couldn't bear the internet stigma and mockery. Not to mention her job as a detective was suspended as if she were some criminal. The whole world seemed to close in on Rose until redemption came in the form of a dangerous offer. When solving a risky murder case was the only way to get back at her ex-husband and also keep her child safe, how far would she go to ruin her ex?

‘The Silent Patient’ by Alex Michaelides hinges on this technique. The primary timeline follows a psychotherapist trying to unravel why his patient, a famous painter, suddenly stopped speaking after allegedly murdering her husband. Interspersed are entries from the patient’s hidden diary, which detail the events leading up to the murder. The tension comes from the gap between the therapist’s present-day deductions and the past’s visceral, emotional account, and the moment they collide is devastating.
I’d add 'The Family Upstairs' by Lisa Jewell to this list. It juggles three perspectives, but two are essentially dual timelines: one following the events inside a notorious London house 25 years ago, and another following a woman in the present who has just inherited it. The past timeline is claustrophobic and cult-like, while the present is a tense unraveling of identity and hidden history. Jewell drip-feeds revelations across both timelines so expertly that it’s nearly impossible to put down.
Practical tip: when searching for these, use the term 'split-time romance' or 'dual timeline romance' on sites like Goodreads. The mystery element is often implied. The Christian fiction market actually has a huge, well-established split-time genre, though the twists are usually less dark and the romantic endings are guaranteed. Authors like Kristy Cambron or Rachel Hauck write them with settings like WWII and modern day. Even if it's not your usual genre, the structure is consistently solid, focusing on heritage, faith, and legacy. The 'mystery' is often a family secret or lost heirloom. It's a fascinating sub-section of publishing that has the formula down to a science. Might be worth a glance if you're after comfort and clean storytelling with guaranteed emotional payoff, even if the theological aspect isn't your thing.
I keep a dedicated Goodreads shelf for this exact trope! It's my comfort zone. There's something about the predictable structure—mystery presented, past explored, clues gathered, truth revealed—that's deeply satisfying, especially when the romance gives it emotional weight. You know the beats, but the fun is in the execution: the specific historical setting, the nature of the secret, the chemistry between the past couple, and how cleverly the modern sleuth puts it all together.
It's the literary equivalent of a warm blanket and a puzzle box. You get the swoon of a historical romance without it being pure fluff, and the intellectual engagement of a mystery without it being too cold or violent. The dual timeline provides built-in pacing, cutting away at tense moments to keep you reading. It's a brilliantly engineered genre hybrid.
