9 of the Best Halloween Mystery Novels for Spooky Season Sleuthing

Starting off with a classic (and the inspiration for the A Haunting in Venice movie), this installment of the Hercule Poirot series is centered around a party chaperoned by mystery author Ariadne Oliver. When one of the guests — a teenager who claimed she once witnessed a murder — is killed, Poirot is called in to both catch the killer and investigate whether there was truth to the victim’s claims.

Recently adapted into a Hallmark film, this paranormal cozy mystery makes for excellent Halloween reading and watching! The last thing violinist Gethsemane Brown expects after moving into a quaint Irish village is to conduct a murder investigation.

But when she discovers that her house is haunted by an alleged murderer — whose unrestful spirit swears he was framed — she has no choice if she wants any peace and quiet. The killer is indeed still at large, and the more Gethsemane, the more she puts herself in grave danger.

As a reader, I’ve never been happier than seeing this series finally get the love it deserves on TikTok. It has *the* perfect autumnal vibes, set at a cozy New England bed-and-breakfast run by two witch sisters who couldn’t be more different. Their niece, Brynn Warren, has recently returned home following the sudden death of her husband. While mourning his loss, Brynn must also reconnect with her repressed powers to clear her aunt’s name when one of the B&B guests is found dead.

The best way I’ve heard this series described is Gilmore Girls meets Practical Magic. It’s clever, atmospheric, and full of memorable characters. It’s an excellent choice to get into the Halloween spirit while doing some armchair sleuthing.

Claire and Sophie are inseparable best friends—in part because Claire is a medium and Sophie is a ghost, murdered ten years ago while they were both in high school. When Claire is hired to perform a seance at a wealthy family’s English mansion for their matriarch’s 80th birthday, she discovers a troubled spirit on the premises and takes it upon herself to (with Sophie’s help) discover who among the family is a murderer.

Miriam Quiñones-Smith is a Cuban American food anthropologist who hosts a cooking show in Miami and has recently discovered her knack for solving crimes.

Unfortunately, while she doesn’t seek cases out, they seem to find her when she’s at her busiest. In between Halloween festivities, she must investigate the death of a local chef who was hired to cater at the Women’s Club fall gala. Read to the end for themed recipes!

While mourning the loss of her husband, Odessa Jones decides to close their shared catering business and make a career change into real estate. All this while also managing her psychic powers, which give her visions at the most unexpected times.

Thankfully, Odessa has her eccentric Aunt Phoenix to comfort her and help her manage her second sight…and assist her with some amateur sleuthing when she receives a vision that the prime suspect for local murder is innocent.

With a tagline like, “Be gay, solve crimes, take naps,” you know you’re in for a delightful mystery. Meet the Undetectables, a coven of witches (and one ghost, who also happens to be their first client…no, the case didn’t go well) who moonlight as a detective agency in their small town.

When they’re called to face off against the Whistler — a supernatural serial killer — they must unravel the clues left behind quickly or risk becoming part of the body count. Metaphorically speaking, of course, for the ghostly member of their coven, but a very real threat for the rest of them.

Evelyn Grace is an heiress in 1950s New York City struggling with agoraphobia following her mother’s death. While she calls her father’s Pinnacle Hotel home, she’s trying to expand the number of places she feels comfortable in and make new friends.

Now Alexandra must catch the real killer while investigating her family history and discover whether there’s any truth to the rumor that they were descended from water witches.
