Best Mystery Books for Book Clubs in 2026

Four retirees in a sleepy English village meet weekly to solve cold cases — until a real murder lands on their doorstep. Richard Osman's debut is warm, wickedly funny, and impossible to put down. For book clubs, it's a goldmine: the characters debate motive and evidence with the same passion your members will, and the novel's humor makes it a rare mystery that feels genuinely joyful. Expect lively debate about which member of the Thursday Murder Club your group most resembles.

Donna Tartt's landmark novel inverts the classic mystery: we know who died and who's responsible from the very first page. The tension lies in understanding why. Set among a tight-knit group of classics students at a Vermont college, this dark, literary thriller raises profound questions about beauty, guilt, and moral complicity. Book clubs will find themselves arguing about whether any character is truly sympathetic — and whether that even matters. A masterclass in slow-burn suspense.

While not a traditional whodunit, this novel has a central mystery at its heart: what really happened to Elizabeth Zott's partner, and can she rebuild her life in a world that refuses to take her seriously? Set in 1960s California, it blends feminist themes, dry humor, and genuine suspense into something wholly original. Book clubs that love character-driven stories with social commentary will have no shortage of things to say — especially about how much (or how little) has changed.

Leigh Bardugo steps into dark adult fantasy-mystery territory with this gripping Yale-set thriller about secret societies, magic, and a young woman determined to uncover the truth about a murder the university would rather ignore. It's propulsive, atmospheric, and genuinely unsettling. For book clubs, the themes of privilege, institutional silence, and survival make for electric discussion. A note: the book deals with heavy topics including trauma and assault, so a brief content note to members beforehand is always a good idea.

Entirely told through emails, text messages, and WhatsApp threads among an amateur dramatic society, The Appeal is one of the most inventive mystery novels of recent years. Two law students are asked to find evidence of a murderer lurking in the correspondence — and so is your book club. It's an interactive puzzle that practically demands group reading. Members will end up highlighting different suspects, making the reveal discussion genuinely surprising. Brilliant fun for a group that wants to feel like detectives.

Tana French's debut, the first in her beloved Dublin Murder Squad series, follows a detective investigating a murder near the same woods where he disappeared as a child — with no memory of what happened. French's prose is luminous, her characters are messy and human, and her endings are famously brave. Book clubs will debate the novel's conclusion passionately, and many members will immediately want to read the rest of the series. Fair warning: have a list of follow-up books ready.

No list of the best mystery books for book clubs would be complete without the queen of crime. Christie's masterpiece — ten strangers lured to an isolated island, killed one by one — remains the best-selling mystery novel of all time for a reason. It's a perfect puzzle box, and reading it as a group lets everyone speculate wildly before the solution is revealed. For clubs that haven't read it, this is a genuine event. For those revisiting it, the craft becomes even more impressive the second time around.

From the author of The Silent Patient comes this atmospheric Cambridge-set thriller about a group therapist who becomes obsessed with proving that a revered Greek tragedy professor is a murderer. Michealides weaves Greek mythology throughout the narrative, giving book clubs a rich secondary topic to explore alongside the central mystery. Is the protagonist reliable? Is obsession a form of guilt? These are exactly the kinds of questions that make for a memorable evening.
