‘The Monkey’s Raincoat’ by Robert Crais (1987)

Kicking off the first story involving private investigator Elvis Cole and his partner Joe Pike, The Monkey’s Raincoat is high-energy fun. Written by Robert Crais, the mystery novel follows Elvis as he’s hired by Ellen Lang to find her missing husband, Mort, and their young son, Perry, who vanished after Mort failed to pick the boy up from school. What begins as a seemingly simple missing-persons case spirals into a dark underworld of Hollywood parties, drug dealing, extortion, and wealthy ex-bullfighter Dom Duran. Earning the 1988 Anthony Award for “Best Paperback Original” at Bouchercon XIX and the 1988 Mystery Readers International Macavity Award for “Best First Novel,” The Monkey’s Raincoat set the tone for Crais’ subsequent stories.

The Monkey’s Raincoat is a barrel of fun thanks to its sharp-witted protagonist, fast-paced banter, and fresh spin on classic California noir. Unlike the gloomy private eyes of yore, Crais crafts Elvis to be a wise-cracking, thirty-something “man-child” who watches cartoons, loves Disney trivia, quotes Jiminy Cricket, and has a rescue cat that drinks beer. It’s a stark contrast to his partner-in-crime, the silent, hyper-violent, wraparound-sunglasses-wearing Joe. They create the perfect chalk-and-cheese dynamic that cuts through the darker underbelly they navigate. A quick, breezy page-turner, Crais uses his snappy background in television writing to start a franchise.

‘The Three Dahlias’ by Katy Watson (2022)

A newfound hidden gem, The Three Dahlias by Katy Watson is the ultimate old-fashioned-tinged, cozy comfort read. The country-house mystery follows three rival actresses, Rosalind King, Caro Hooper, and Posy Star, who all played the famous 1930s fictional detective Dahlia Lively, as they gather at Aldermere, the estate of the character’s late creator, Lettice Davenport. When the weekend gathering turns deadly, the three women must set aside their generational differences and rivalries to solve real-life murders, with clues that might be hidden in Davenport’s own books. The first novel of Watson’s series, The Three Dahlias is light and frothy fun.

The Three Dahlias gives readers of any generation something to attach to thanks to the trio of women at the center of the story. Their backstories couldn’t be so drastically different, yet seeing them come together for the common goal is the draw. Each Dahlia has a distinct approach to investigation, giving the story natural twists, turns, and conflicts. Setting it at a fan convention gives the story a fun, uniquely intimate backdrop. The story follows them as they try to sneak around to outwit the murderer before more chaos ensues. Watson’s prose is filled with accessible wit and charm. Because she built such a delightful world with three dynamic women, it’s clear she was eager to continue their adventures.

‘One for the Money’ by Janet Evanovich (1994)

Bounty hunter Stephanie Plum got her start in Janet Evanovich’s One for the Money. The comedy mystery novel follows Stephanie, a 30-year-old former lingerie buyer from Trenton, New Jersey. Out of work, broke, and facing car repossession, she blackmails her sleazy bail-bond cousin, Vinnie, into hiring her as an apprehension agent. She is sent to hunt down Joe Morelli, a former vice cop and her former high school flame, who is accused of murdering an unarmed man. With no law enforcement training, the over-her-head Stephanie relies on guidance from bounty hunter Ranger as she tries to earn her first major payday. Appearing for 75 weeks on USA Today’s list of 150 best-selling novels, peaking at number 13, One for the Money trades a gloomy murder mystery in exchange for a female-driven underdog story.

One for the Money celebrates chutzpah. Stephanie is an unlikely individual to embark on a high-stakes chase, but her ingenuity and pure grit make her a compelling protagonist. She’s stubborn and determined, never letting a hiccup prevent her from her objective. She stumbles and bumbles, yet still solves the mystery. The story has a unique allure: her first mark is an old flame, adding a messy, unpredictable subplot to the larger story. With eccentric, colorful side characters, One for the Money was the anti-bleak novel during an era of darker tales. It’s pure action meets comedy. In 2012, One for the Money was adapted into a film starring Katherine Heigl as Stephanie, Jason O’Mara as Joe, and Daniel Sunjata as Ranger. Unfortunately, it was a commercial flop, unlike its source material.

‘The A.B.C. Murders’ by Agatha Christie (1936)

There are quite a few adjectives and superlatives you could use to describe Agatha Christie, but fun may not always come to mind. And yet, if one novel fits the bill, it’s The A.B.C. Murders. Featuring the renowned Hercule Poirot, the story centers on a serial killer who begins targeting people across England in alphabetical order, sending advance warning letters signed “A.B.C.” to Poirot. Poirot and his associates race against time to stop the alphabetical killings while dealing with public panic and a taunting adversary. With twists, turns, and red herrings, Christie breaks from her usual country-house formula for a high-stakes cat-and-mouse game and an eerie, elementary puzzle to decode.

The fun lies in the alphabet challenge that Poirot is forced to endure. Instead of a hidden family drama or inheritance dispute, the sleuth gets his warnings ahead of time, signaling where and when the next murder will happen. Poirot is joined by Captain Arthur Hastings, who brings delicious chemistry and often leads to plenty of humor as he tries to decode the investigator’s mysterious, cryptic retorts. In a ticking-clock narrative, Christie keeps readers on their toes as she occasionally flips perspectives from Hastings’ classic first-person to third-person chapters focused on the bewildered prime suspect, Alexander Bonaparte Cust. The novel was first adapted in 1965 as The Alphabet Murders starring Tony Randall, and later in 2018 for a three-part miniseries starring John Malkovich and Rupert Grint.

‘Finlay Donovan is Killing It’ by Elle Cosimano (2021)

In the debut of Elle Cosimano’s series, Finlay Donovan is Killing It follows the titular struggling single mother of two and a stressed author who is mistaken for a professional contract killer while at lunch with her literary agent. Facing severe financial ruin, custody threats from her ex-husband, and a looming deadline, Finlay inadvertently accepts a cash offer to eliminate a troublesome husband, only to quickly learn that real-life crime is much messier than fiction. But at least she can get book inspiration out of it! A uniquely giddy and fast-paced mystery, Finlay Donovan is Killing It blends slapstick humor, accessible single-parent chaos, and high-stakes suburban crime into a witty mystery satire.

Unlike traditional slick or stoic sleuths, the titular mystery solver’s life is a relatable mess. She’s unpolished but determined, making Finlay someone you want to root for. The novel mixes laugh-out-loud domestic comedy, cozy-mystery energy, a splash of romance, and scary mob-level danger into a juicy comedic thrill ride. The mystery unfolds smartly as Finlay takes a do-what-you-know approach, using her writing experience to lead the way. Finlay isn’t the only brightly crafted character; Vero, her quick-witted nanny, is her fearless partner-in-crime. Finlay Donovan Is Killing It is a series waiting to happen.

‘Every Time I Go on Vacation, Someone Dies’ by Catherine Mack (2024)

If ever there was a fun title that would hook you immediately, look no further than Every Time I Go on Vacation, Someone Dies by Catherine Mack. The story follows author Eleanor Dash during her 10-day, six-city book tour across Italy. Her main goal is to figure out how to kill off Connor Smith, her infuriating ex and the inspiration for her main character, only to find real life imitating her fiction when someone actually tries to murder the real Connor. Eleanor must juggle literary rivals, intense fans, a stalker, her sister/assistant Harper, and her unexpected ex-boyfriend Oliver while trying to solve three bodies’ worth of sudden murders. Known for its witty tone, sun-soaked locale, and smarmy protagonist, Every Time I Go on Vacation, Someone Dies kicked off Mack’s Vacation book series.

With lighthearted banter, flirty situations, and a fun, accessible world, Every Time I Go on Vacation, Someone Dies uses snarky author footnotes to break the fourth wall and set itself apart from other mystery books in the genre. The book also doubles as an escapist travel read thanks to its luscious locale. With a colorful cast of suspects, Mack keeps her readers engaged as any of the eccentric, unpredictable individuals could be the culprit. Though it does lean a bit more profanity-heavy than some typical cozy mystery reads, Every Time I Go on Vacation, Someone Dies is a wonderful read.

‘Vera Wong’s Unsolicited Advice for Murderers’ by Jesse Q. Sutanato (2023)

Written by Chinese-Indonesian author Jesse Q. Sutanto, the delightful Vera Wong’s Unsolicited Advice for Murderers follows Vera Wong, a lonely, overbearing 60-year-old Chinese-American tea shop owner in San Francisco’s Chinatown who decides to solve a murder herself when Marshall Chen is found dead on her shop floor. Before calling the police, Vera outlines the body with a Sharpie and snatches a flash drive clutched in the dead man’s hand, convinced the authorities won’t do a proper job. Zeroing in on four main visitors who all happen to have complicated connections to the victim, Vera’s investigation eventually devolves into feeding the suspects home-cooked meals, giving them heavy-handed life advice, and meddling in their personal problems. A silly little story about found family that satires and celebrates classic “Asian auntie” behavior, the novel’s heart is finding a vibrant second act in life and the power of connection.

Sutanto flips the traditional whodunit on its head by replacing a hardboiled detective with a sharp-tongued, big-hearted 60-year-old Chinese tea-shop owner. With a quirky heroine at the center, readers are instantly drawn into Vera’s internal monologue, packed with humorous judgments about young people, modern technology, and everyone else’s failure to live up to her strict schedule and standards. The humor is deeply rooted in a classic archetype, combining biting sarcasm, constant feeding, and deep-seated emotional care. The book won an Edgar Allan Poe Award for Best Paperback Original. If you loved the book, it is being developed for television!

‘The Thursday Murder Club’ by Richard Osman (2020)

The cozy mystery genre was revitalized in 2020 by The Thursday Murder Club by Richard Osman. The story centers on four elderly friends living in a luxury retirement village who gather weekly to review and debate unsolved police cold cases. Their hobby turns practical when they must team up to solve a live murder case of a local builder connected to the retirement village’s development. Using their varied life experience and the fact that younger people often underestimate them, the friends launch a parallel investigation alongside local police officers DCI Chris Hudson and PC Donna De Freitas. A witty, twisted whodunit with heartfelt, humorous explorations of aging, grief, and friendship, The Thursday Murder Club is a simply joyous read.

The Thursday Murder Club shifts away from the era’s darker crime stories to remind readers how fun and charming mysteries can be. With a lovable cast of characters, witty humor, and a cozy British setting, the novel is rooted in heart. A quartet of unlikely detectives leads the charge, giving them an underdog advantage that makes their investigation seamless. They can slip past police lines, interview suspects, and dig up clues that baffle actual detectives. The story is filled with warm human moments as Osman explores the realities of aging through themes of grief, memory loss, and physical decline while still celebrating their sharp minds, mischief, and deep companionship. A fast-paced puzzle, The Thursday Murder Club served as the perfect fun mystery to be adapted for film. The Netflix crime comedy starred Helen Mirren, Ben Kingsley, Pierce Brosnan, and Celia Imrie.
