1. The Seven and a Half Deaths of Evelyn Hardcastle by Stuart Turton

Kicking off our list is a modern masterpiece that redefines the fantasy mystery genre with its intricate, time-bending narrative. Published in 2018, this standalone novel follows Aiden Bishop, who wakes up in a stranger's body at a crumbling English estate called Blackheath. He's trapped in a loop, reliving the same day eight times in different hosts, all to solve the murder of Evelyn Hardcastle before the clock resets. But this isn't just any murder—it's laced with supernatural elements, including body-swapping and hints of otherworldly forces manipulating events.

What makes this book a standout is its homage to classic mysteries like Agatha Christie's And Then There Were None, but infused with fantasy flair. Turton masterfully plants clues across timelines, forcing readers to track details from multiple perspectives. Fun fact: The title's "seven and a half" refers to the number of hosts Aiden inhabits, a clever nod to the puzzle's complexity. Stuart Turton, a former journalist, drew inspiration from quantum physics and Golden Age detective stories, creating a debut that won the Costa First Novel Award and was optioned for a Netflix series. Readers praise its mind-bending twists that reward rereads—perfect for fans of locked-room mysteries with a magical edge. If you love games like Clue elevated to epic proportions, this is your gateway drug to fantasy mystery.

Critics on sites like Reddit highlight how the book's structure mirrors a video game, with "levels" unlocking new clues, making it one of the most innovative entries in the genre. With over 4.1 average rating on Goodreads from hundreds of thousands of reviews, it's a must-read for anyone seeking intellectual thrills wrapped in fantasy.

2. The Harry Potter Series by J.K. Rowling

No list of fantasy mysteries would be complete without the iconic Harry Potter series, which spans seven books starting with Harry Potter and the Sorcerer's Stone (1997). At its core, this is the story of an orphaned boy discovering he's a wizard and attending Hogwarts School of Witchcraft and Wizardry. But beneath the spells and Quidditch matches lies a masterful mystery arc: Who is the Dark Lord Voldemort, and how does Harry's past connect to a web of prophecies, hidden artifacts, and betrayals?

Each book centers on a self-contained mystery—like the secret of the Chamber of Secrets or the identity of the Prisoner of Azkaban—while building toward the overarching enigma of Voldemort's return. Rowling litters the narrative with subtle clues, from seemingly innocuous details in early chapters to foreshadowing that pays off books later. Interesting fact: Rowling planned the entire series outline on a napkin during a train ride, embedding Easter eggs like the significance of Snape's patronus or the Horcruxes that fans still debate decades later. The series has sold over 600 million copies worldwide, inspiring theme parks, films, and a cultural phenomenon. J.K. Rowling, who wrote the first book while on welfare, drew from mythology, alchemy, and real-world history to craft a world where magic amplifies moral dilemmas and detective work.

What elevates Harry Potter to fantasy mystery royalty is its blend of wonder and suspense; Harry's investigations often involve forbidden spells, invisible cloaks, and polyjuice potions as tools for sleuthing. It's accessible for all ages yet layered enough for adults to uncover new twists on rereads. If you're new, start with the first book—it's a portal to a universe where every wand flick hides a potential clue.

The series shines in its unexpected twists and clues littered throughout the books, making it a puzzle-lover's dream. The Monarch's Inferno amps up the mystery with omens—circling owls, fleeing butterflies, and blood-red poppies—that serve as clues to the Mistress's identity and the realm's darkening secrets. Readers are kept guessing as alliances shift and perceptions prove unreliable, with twists that tie back to overlooked details from earlier scenes.
