Miss Hortense and the Last Rites – Mel Pennant

When Bigglesweigh’s most feared gangster, “Nine Lives” Cuttah, finally runs out of luck, he leaves behind a list of people who might want him dead – and retired NHS nurse Miss Hortense is on it.

With only days before his vengeful cronies come calling, she must pick apart Cuttah’s messy web of drug deals, bent coppers, estate rivalries and an old case involving a missing girl that still haunts the community.

Surrounded by neighbors, frenemies and family with secrets of their own, Miss Hortense brings sharp humor and steel‑nerved tenacity to a vibrant, Jamaican‑British town mystery.

Mad Mabel – Sally Hepworth

Eighty‑one‑year‑old Elsie Mabel Fitzpatrick has spent six decades hiding on a quiet Melbourne street, determined to outlive the legend that once branded her “Mad Mabel,” the youngest person in Australia ever convicted of murder.

When a neighbor she openly disliked is found dead, and Elsie discovers the body, her carefully protected identity unravels and she becomes a suspect all over again.

As she agrees to tell her story to two true‑crime YouTubers, the narrative toggles between her toxic childhood and her prickly present, where an inquisitive seven‑year‑old neighbor and a yappy dog insist on seeing the vulnerable woman behind the myth.

From Murder with Love – M. R. G. Davies

Release Date: July 10th

From Murder with Love is book 3 in the Cosy Crime Club Mystery series, and this time the four members of Norcester’s murder‑mystery reading group are invited to a special weekend honoring their favorite detective novelist.

It feels like a dream come true, but the opening of the late author’s private archive, sealed for fifty years, unleashes a very real body and a very present danger.

Suddenly, their bookish expertise is all that stands between them and a killer tied to Cold War intrigues, a Russian spy who won’t quit, and a runaway train loaded with stolen treasures – and clues.

Forgive Us Our Trespasses – Penny Stephens

Release Date: July 16th

Reverend Clare Brakespear thinks a week in Cornwall leading the Morva Hotel’s “Refresh and Renew” retreat will mean sea air, gentle prayer and long walks on the beach.

Instead, she walks straight into a storm of unresolved grudges and buried truths. As guests arrive, old rivalries flare, loyalties shift and it becomes clear that everyone is hiding something – including what really happened to a person who vanished a year ago.

When fresh evidence surfaces, Clare is forced back into an uneasy partnership with the ever‑brusque DCI Jackie Carter, racing to unmask a killer before this peaceful getaway turns lethal.

The Cherkley Court Conundrum – Benedict Brown

Release Date: July 17th

When an old flame appears on Marius Quin’s doorstep with news of a shocking crime at Cherkley Court, he and Lady Bella are swiftly lured into another tangle of lies and murder.

A loyal maid has been savagely attacked, a priceless jewelry box is missing, and the estate’s head gardener has vanished, leaving everyone eager to label him the culprit.

But Lord Sheridan, his dazzling wife, the bohemian young artists in residence and the tight‑lipped staff all have something to hide.

As Marius follows his instincts and the killer strikes again, he and Bella must unpick a conspiracy rooted deep in the household before the murderer escapes justice twice.

The Emerald Teapot – Rosalie Oaks

Release Date: July 18th

Elinor imagined a blissfully uneventful honeymoon in Regency Brighton with sea breezes, gentle promenades and time alone with her new husband.

Instead, a lethal wedding gift leaves her convinced that she, the bride, was the real target, and their borrowed house swiftly fills with anxious relatives determined to “protect” her.

Sensibly, Elinor decides the best way to investigate is to go undercover as her own widowed mother, using her growing divination powers to trace a would‑be killer.

A Murder at the Mansion – Ellie Alexander

Release Date: July 21st

In Redwood Grove, even the most imposing mansion can’t keep its secrets locked away!

When reclusive heiress Bernadette Garst disappears from her vast estate, bookshop owner–turned–investigator Annie Murray and her partner Fletcher are called in to untangle the mystery.

Relying on her sharp observational skills, literary instincts, and a loyal circle of friends, Annie must decode the clues hidden in the opulent grounds before the mansion’s secrets turn deadly.

Tell Tale – Claire Parkin

Release Date: July 23rd

Llanfair’s most infamous tell‑tale, Debbie‑Marie Tunstall, has always had a talent for getting on everyone’s nerves with her relentless snooping and brutally honest entries in her cherished Kajagoogoo notebook.

In the summer of 1984, she finally pushes the village too far and runs away – only to stumble into real danger as the sole witness to a chilling murder.

Convinced a serial killer may be stalking their quiet Welsh community, Debbie starts connecting a decades‑old tragedy with what she’s just seen.

But in a place where no one trusts her version of events, unearthing the truth could tear Llanfair apart.

The Campervan Detectives – Maeve Haran

Release Date: July 28th

Newly single and decidedly not in the mood for midlife reinvention, Sadie Sutton flees her imploded marriage in a vintage orange VW campervan and heads back to the seaside town of Winching – only to literally trip over a corpse on a coastal walk.

When the balaclava‑clad figure she glimpses at the scene vanishes into the night, Sadie can’t resist investigating the death of feared retired headmistress Charlotte Woolf.

With help from three female “van‑life” friends, a dog named Sam Spade and a gossipy sea‑swimming club, she chases clues through campsites and cliff paths in a buoyant, distinctly British cozy mystery.

All Killers Aboard – David Fennell

Release Date: July 30th

David Fennell’s All Killers Aboard traps readers on a luxury cruise from Southampton to New York that secretly hosts the Midnight Chorus Society, an exclusive convention for serial killers, would‑be murderers and their morbid fans.

Glamorous TV detective Jacqui Dulac and her ghostwriter Martha Hammond expect research and relaxation, not a very real corpse marked only by a sinister red button.

Forced to investigate on a ship where almost everyone might be a predator, the pair navigate dark humor, meta crime‑fiction in‑jokes and escalating set‑pieces in what early buzz hails as a high‑concept, wickedly entertaining thriller.

Looking Forward To July 2026

If there’s a thread running through all of the July 2026 releases, it’s that ordinary people are far more resourceful, and nosy, than they first appear.

From faintly shambolic vicars and bookshop owners to runaway tell‑tales and honeymooning diviners, these stories hand the magnifying glass to characters you’d happily sit next to in a café and then watch them walk straight into trouble.

Whether you fancy armchair sleuthing in a Cornish hotel, a Brighton townhouse, or on a transatlantic cruise, there’s plenty here to fill your TBR, and maybe keep you glancing over your shoulder on your next summer holiday!
