Must-Read Mysteries of 2025

Anthony Horowitz’s Marble Hall Murders is the kind of mystery that makes you feel like you’ve stepped straight into a gleaming, old-school manor house, only to find the doors locked, the lights flickering, and a killer who’s always one clever move ahead.

Horowitz mixes classic whodunnit charm with razor-sharp modern twists, delivering a puzzle so intricately designed you can hear the gears turning as you read. Every suspect oozes motive, every room hides a secret, and every clue dares you to shout, “Aha!”... right before Horowitz pulls the rug out from under you.

If you love mysteries that feel elegant, wickedly clever, and just self-aware enough to wink at the genre’s golden age, Marble Hall Murders is the perfect book to devour in one delicious, twisty binge and one of the year’s best.

If you love a mystery threaded with obsession, grief, and the dark corners of the internet, This Book Will Bury Me by Ashley Winstead is absolutely your kind of thriller. After Jane Sharp loses her dad, she throws herself into a true-crime forum and ends up part of a tight-knit crew of online sleuths. When a horrific triple murder in a sorority house in Idaho ignites a viral frenzy, Jane and her cyber-detective friends decide to "go real" and dive headfirst into the case in person.

The mystery here is so satisfying: clues that don’t quite add up, reams of internet theorycraft, and a killer who might just be smarter than everyone thinks. But it’s not just a whodunnit. Winstead laces in raw grief and loneliness, making Jane’s journey deeply emotional.

If you’ve binged true crime, chased conspiracies in online forums, or just love a twisty, character-driven mystery that questions what justice really means, this is the book that will bury you (in the best way).

Richard Osman’s The Impossible Fortune pulls you into a mystery that feels like a perfectly orchestrated puzzle, and one you think you can solve… until he flips the board with that signature, cheeky grin. This story crackles with clever clues, misdirection that actually earns its surprises, and characters who banter their way through danger with the kind of warmth and wit only Osman can pull off.

You’re not just watching a mystery unfold. You’re in it. Scanning every line for the hidden thread, only to realize Osman has already tied it into a knot while you were admiring the scenery. It’s playful, intricate, and delightfully twisty, the kind of book that makes you stay up far too late whispering, "Just one more chapter."

If you love a mystery that keeps your brain buzzing, your heart invested, and your grin firmly in place, this is absolutely one to dive into.

S.A. Cosby’s King of Ashes is the kind of mystery that grabs you by the collar and pulls you straight into heavy, smothering smoke that’s thick, dark, and humming with danger. Cosby doesn’t just tell a story; he drags you through a world where every shadow hides a secret and every truth arrives with teeth.

This is a mystery built on tension that simmers until it boils over, with twists that don’t just surprise you, they sting. Cosby’s characters feel raw and real, haunted by choices that make every reveal hit harder. You’re constantly second-guessing yourself, convinced you’ve figured it out… until Cosby pulls the rug from under your feet and proves you wrong.

If you crave a mystery that’s gritty, propulsive, and bursting with emotional weight, King of Ashes is the kind of book that won’t just keep you turning pages, it’ll stay under your skin long after you’re done.

Ruth Ware’s The Woman in Suite 11 is the kind of mystery that makes you instantly suspicious of everyone, including yourself. From the moment the door clicks shut on that eerie hotel suite, Ware winds you up with creeping tension, razor-sharp twists, and that delicious “wait… WHAT?” feeling only she can deliver.

This isn’t a gentle, puzzle-box mystery, it’s the type where every chapter ends like a dropped match, sparks flying, daring you not to keep reading. Ware plays with perception so well that you’ll constantly question what’s real, what’s imagined, and who’s hiding the truth in plain sight.

If you love mysteries that feel claustrophobic, clever, and just unpredictable enough to make you gasp out loud, The Woman in Suite 11 is absolutely your next late-night obsession.

Dan Brown’s The Secret of Secrets is pure, pulse-quickening mystery bliss, the kind where you swear you’ll stop after one chapter, then suddenly it’s 2 a.m. Brown drops you into a world of hidden societies, encrypted manuscripts, and ancient clues that feel just real enough to make you wonder what’s actually lurking in our museums and libraries.

The mystery unspools fast and sharp: every revelation sparks another question, every symbol hides a deeper layer, and every character has an agenda you know you’re not seeing clearly. Brown’s trademark mix of history, danger, and brain-teasing puzzles turns the entire book into a treasure hunt you can’t look away from.

If you crave a story that makes your heart race and your brain buzz, The Secret of Secrets is exactly the kind of high-stakes, twist-heavy mystery you’ll tear through in a single, breathless gulp.
