Last Updated on May 6, 2026
There must be hundreds, if not thousands, of new books getting released in May 2026, and while the vast majority do not fall into the cozy mystery category, we still have an abundance to choose from when it comes to updating our reading pile.
When it comes to writing articles like this, I genuinely try to get as good a mix as possible, all in the hopes that you can find one or two that will pique your interest.
I know that time is often in short supply, and new books cost money, so nobody wants to waste either. With that in mind, I’ve put together some great new cozy mysteries with a couple of nods to the more crime thriller side of things.
As an added little note, I have already read Voted Most Likely to Murder by Lacey Moone and 138 Main Street by Gavin Bell, and I can confidently say that both get a huge thumbs up from me.
In fact, Voted Most Likely to Murder quickly became one of my favorite cozy mysteries this year, and I cannot wait for Lacey Moone to give us another installment.
So, if you fancy getting an update on what is coming your way in May 2026, then read on…
138 Main Street By Gavin Bell
May 7th
138 Main Street is a thriller built around one chilling idea: a murderer is targeting the most ordinary address in America.
In four weeks, eight people in different states have been killed, all living at 138 Main Street, and that’s only the beginning.
FBI Special Agent Ben Walker teams up with rookie officer Zoe Hill when they realize there are more than 7,600 Main Streets across the United States, and any of them could be next.
As the so‑called Main Street Killer’s manifesto hits the media, panic spreads, and the investigation turns into a race against time across small towns and big cities.
If you like tense, procedural‑style cat‑and‑mouse stories with a strong, capable heroine, this one is especially gripping.
Shrink Solves Murder by Philippa Perry
May 7th
Shrink Solves Murder introduces Patricia Philipps, a psychotherapist whose quiet professional life takes a turn when a body washes up near Beachy Head.
The victim is Henry Clayton, her three o’clock patient, and while the police write it off as suicide, Pat’s training tells her something more sinister is going on.
Used to listening to secrets, resentments, and fantasies, she starts to notice the motives everyone else overlooks and becomes convinced that Henry was murdered.
With plenty of therapeutic insight and with a classic amateur sleuth setup, this looks like a winner if you like character‑driven mysteries with a thoughtful, slightly offbeat detective.
Voted Most Likely to Murder by Lacey Moone
May 12th
I love, love, love this book, which is a cozy debut built around a high school reunion that turns into a hotbed of old grudges and fresh crime.
Belinda Bishop is a messy, magnetic heroine who returns to Nova Scotia jobless, snarky, and not quite ready to face the ghosts of her teenage years.
When a dead body crashes the high school reunion festivities, Belinda finds herself poking into motives she thought she’d left behind, alongside her current bestie, Stevie, and former bestie Jolene, who also happens to be the prime suspect.
It was an absolute pleasure to spend time beside these three women as they bicker, tease, support, and occasionally exasperate each other, all while they try to figure out who killed their former classmate and why.
This Weekend Doesn’t End Well for Anyone by Catherine Mack
May 14th
In This Weekend Doesn’t End Well for Anyone, mystery author Eleanor Dash is hoping for a rare break: an all‑inclusive resort weekend where she’s speaking at a conference for crime writers.
Her plans collapse the moment she checks into her room and finds a dead body on the floor, turning her relaxing getaway into a real‑life whodunit.
The resort is packed with familiar faces and fellow writers, any of whom could be the intended victim, the killer, or both.
Because these people all understand how to construct the perfect crime, Eleanor has to rely on her instincts and storytelling smarts to stay one step ahead and make it out alive.
Ideal if you like meta mysteries about mystery writers, set in a closed, all‑inclusive setting.
The Library After Dark by Ande Pliego
May 14th
The Library After Dark is set in a notorious library with a long shadow of strange disappearances and bizarre accidents.
Tonight, its doors are opened to a handful of carefully chosen visitors for an exclusive after‑hours tour: a bestselling author, a curious journalist, an academic professor, a bookseller, and an architect.
They’ve been invited to view a legendary, impossibly valuable book, but each of them is also harboring a private agenda that has nothing to do with rare manuscripts.
As they’re led deeper into the building, one guest dies in a shocking, seemingly impossible way, and the survivors suddenly understand that they may not all make it out.
Trapped together, they must hunt for a killer in the stacks, face the worst truths about themselves, and decide which secrets are worth protecting, no matter who has to die to keep them.
The Book Club Murders by Maggie Allswell
May 22nd
From Maggie Allswell comes The Book Club Murders which follows widowed Judy, whose favorite night of the month is gathering with her fellow mystery lovers to dissect fictional killings over wine and salt and vinegar crisps.
Their quiet village routine shatters when Wendy, the local librarian and Judy’s friend, suddenly disappears.
Judy goes looking for her and discovers Wendy dead at home, a copy of Romeo and Juliet clutched in her hand.
The police call it a tragic accident, but Judy knows Wendy loathed Shakespeare and is sure someone staged the scene.
With her book club by her side, she begins digging into town gossip and quickly finds no shortage of suspects, and quickly Judy realizes she’ll need every bit of her armchair‑detective experience to unmask a killer before their cozy club becomes the next chapter in a very real crime story.
The Last Book Club by Joanne Rock
May 26th
Jordyn is new in Saratoga Springs and has just joined a neighborhood reading group, but not to make friends. She is there to investigate a death.
Her foster sister, Tara, belonged to this same club before she was supposedly killed in a hit‑and‑run after a meeting, and Jordyn is convinced it wasn’t an accident.
Each member of the club has a plausible motive, and as Jordyn reads between the lines of their polite conversations, she begins to uncover a web of secrets and grudges.
When the group hosts a themed murder mystery party, the game starts to echo reality a little too closely, and the “pretend” murder angle turns deadly.
It’s pitched as a page‑turning mystery for fans of neighborhood dramas where cozy gatherings hide dangerous truths.
The Divorce by Freida McFadden
May 26th
Freida McFadden turns her psychological thriller lens on the dark side of happily‑ever‑after.
Naomi thinks she has a classic love story until her husband abruptly kicks her out and dives into an expensive, ugly divorce.
Adding insult to injury, she discovers he has already moved in with a much younger woman, and her pain quickly curdles into fixation.
As Naomi becomes obsessed with his new girlfriend, she begins uncovering secrets that set her on a dangerous path and force her to question what really went wrong in her marriage.
Tense, subversive, and pulse‑pounding, this is for you if you enjoy twisty, unreliable‑narrator‑style domestic suspense.
Death by Canapé by Faith Eckersall
May 28th
Death by Canapé is part of Faith Eckersall’s Piddlington Gazette Mystery series, following on from The Body on the Roundabout.
We return to the supposedly quiet Dorset town of Piddlington Minster, where Harry Hedges, long‑suffering editor of the Piddlington Gazette, is once again up to his neck in trouble.
He’s barely recovered from the chaos of last year’s double body discovery on the roundabout when a new string of odd events hits the village.
Someone is sneaking sinister effigies into the local Model Village, and one of them is an unmistakable likeness of the mayoress, a woman with grand redevelopment plans and an even longer list of enemies.
After a glamorous soirée thrown by the district’s latest celebrity resident, the mayoress is found dead, apparently having choked on a canapé. Harry smells something far juicier than a tragic accident and is determined to prove it.
With only his notebook, his hunches, a green reporter, a grumpy chief sub, and the office Labrador (who seems oddly keen on a role of his own), Harry starts digging.
In a town this small, everyone is under scrutiny, and some secrets won’t survive the spotlight.
Murder on the Cornish Train by J M Hall
May 28th
Murder on the Cornish Train, from JM Hall opens on a wild, stormy night as Jeff boards the sleeper service from London Paddington, bound for the far end of the Cornish coast.
The train rattles through the darkness while waves crash against the line, sealing the passengers into an eerie, rolling bubble of light and shadows.
By the time they arrive in Cornwall the next morning, one passenger has mysteriously disappeared without a trace. The following day, another is discovered dead on a lonely, windswept beach. Jeff refuses to believe these events are unrelated.
As he thinks back over the journey, he realizes he may be the only person who noticed the one detail that links the missing passenger, the dead body, and a killer who almost certainly boarded that Cornish train with them.
Wrapping Up Your Cozy Mystery List For May 2026
Putting this list together, I wanted a mix of classic cozy comforts and slightly edgier reads that still fit the mystery mood many of us are drawn to.
I did realize halfway through the list of new releases in May 2026, that there’s a real slant towards books, bookshops, libraries, and authors in this month’s cozy mystery themes, but each brings something different to the sub-genre!
