Book cover of Code of Conduct

Sharon Michalove Author Of At First Sight

From my list on romance, mystery, and suspense in Chicago.

Why am I passionate about this?

I was born in Chicago and grew up in the suburbs. After a career at the University of Illinois, 150 miles downstate, I moved back to my hometown to recapture the urban vibe that I love. A historian, I love the stories that architecture tells me and wandering the streets of the city never stales. Having romance in my life is important and writing about how relationships can develop in the city is part of that. Everywhere I go in Chicago, I think of how my characters might interact with each other and the setting. Romance can be found in grand restaurants and in odd corners and Chicago has it all.

Sharon's book list on romance, mystery, and suspense in Chicago

Sharon Michalove Why did Sharon love this book?

This book combines romance and suspense, humor, and action, all in one package. Shane, a P. I., and Gabriel, a security expert, are separately investigating a person of interest. They eventually cooperate to catch their villain. This is a slow-burn romance with a stiff-upper-lip Brit, working for Cipher Systems in Chicago and an amputee who takes no prisoners. Their explosive mix makes for an exciting ride with a great love story. 

I loved that both Gabriel and Shane live in The Manor, which is the former British consulate. I’d live there myself if I could afford it. Having characters situated in neighborhoods that I know makes the reading experience more authentic. I also loved how Shane handles being an amputee. Her scenes with her prosthetics designer are hilarious.

** 2021 RWA Vivian Award Finalist – Romantic Suspense **

** Finalist in the 2020 Next Generation Indie Book Awards **

“The slow-burn romance between Gabriel and Shane becomes delicious torture. This is a winner.” – Publishers WeeklyStarred Review

There are three things you need to know about Shane P.I.
1) P.I. is not her last name, it’s her job title,
2) Her specialty is catching cheaters, and
3) She’s a superhuman – kind of.

Gabriel is a security expert for Cipher Security, and a former UN Peacekeeper with a fierce protective streak that finds its focus on the beautiful…


Book cover of Motherless Brooklyn

Richard Scrimger Author Of At the Speed of Gus

From my list on neurodivergent voices, quirky, heartbreaking.

Why am I passionate about this?

I can’t count the number of conversations where I’ve been asked to slow down, or take a breath, or talk in a straight line. My neurodivergent heroes are versions of me: me if I were an alien, or a dying old lady, or a zombie. Gus is the closest I’ve come yet to writing my true self. He’s just me. I want readers who identify with Gus to feel seen and accepted and those who don’t—to understand what it’s like to live like this. And, just maybe, to have a little fun along the way. 

Richard's book list on neurodivergent voices, quirky, heartbreaking

Richard Scrimger Why did Richard love this book?

Plot and style matter, but character is what I engage with. This book is a hilarious and touching portrait. Lionel Essrog doesn’t ‘suffer’ from Tourette’s Syndrome, but he happens to have it. He’s so natural that he completely normalizes his condition.

The plot involves an investigation that is told in Chandleresque prose, a very private-eye noir. Essrog is an unexpected narrator who nevertheless manages to own the story. I don’t use the phrase ‘pitch-perfect’ very often, but it fits here.

NATIONAL BOOK CRITICS CIRCLE AWARD WINNER • A complusively readable riff on the classic detective novel from America's most inventive novelist.

"A half-satirical cross between a literary novel and a hard-boiled crime story narrated by an amateur detective with Tourette's syndrome.... The dialogue crackles with caustic hilarity.... Unexpectedly moving." —The Boston Globe

Brooklyn's very own self-appointed Human Freakshow, Lionel Essrog is an orphan whose Tourettic impulses drive him to bark, count, and rip apart our language in startling and original ways. Together with three veterans of the St. Vincent's Home for Boys, he works for small-time mobster Frank Minna's limo…


Book cover of Save Me from Dangerous Men

K.D. Richards Author Of Pursuit of the Truth

From my list on big city private eyes.

Why am I passionate about this?

I write the West Investigations series, a romantic thriller series, centered around the men and women running a private investigations firm. When I began the series I knew I wanted it to be set in an urban city, not just because I’m a city girl at heart, but because of the eclectic nature, diversity, and color that can be found in the big city. Each of the books I’ve recommended below features a big city PI that jumps off the page, grabs you, and doesn’t let go for 200+ pages.

K.D. Richards Why did K.D. love this book?

I was shocked when I realized S.A. Lelchuck was male.

Nikki Griffin, a hardnosed San Francisco detective slash bookstore owner, is such a dynamic, fleshed-out female character I just assumed she’d been penned by a woman. Well, you know what they say about assuming. Nikki is a kick butt, take no prisoner’s PI with an agenda.

Like the PIs in the books above, she veers onto the wrong side of the tracks often. Actually, she jumps over them and runs along the wrong side of the tracks while brandishing brass knuckles and a baton.

Even when she’s breaking the law, you’re kinda okay with it because, well, Lelchuck’s bad guys are really bad.

Book cover of The Sins of the Fathers

James L. Thane Author Of South of the Deuce

From my list on no fan of crime fiction should miss.

Why am I passionate about this?

I began reading mystery novels while I was still a young boy, thanks to the influence of my parents who were both fans of crime fiction. Early on, I was drawn toward the hard-boiled school of crime fiction and I’ve always particularly enjoyed reading novels about both private detectives and police department detectives. Several years ago, I began writing my own series featuring a Phoenix, Arizona homicide detective, Sean Richardson, and his partner, Maggie McClinton. I’ve also written two fairly traditional mysteries, one set in Montana and the other in South Dakota as well as a standalone suspense novel and one nonfiction book.

James' book list on no fan of crime fiction should miss

James L. Thane Why did James love this book?

This novel introduced Matthew Scudder, an ex-New York City cop turned unlicensed private investigator. In this case, a young woman has been brutally murdered and the police believe they have solved the crime. But the victim’s father hires Scudder to look deeper into the case which will produce more than its share of surprises. The beauty of this series, though, lies in the development of the Matthew Scudder character, who remains one of the most fascinating and compelling figures in all of crime fiction. The first chapter, which introduces Scudder, is one of the best opening chapters of any crime novel.

Book cover of Hercule Poirot's Christmas

Trevor D'Silva Author Of A Bloody Hot Summer

From my list on Agatha Christie and Sir Arthur Conan Doyle.

Why am I passionate about this?

Even though I’m an engineer and accountant by education, I love to write and growing up, I read many historical fiction and murder mysteries. History spanning from the Victorian Era until the mid-twentieth century has always fascinated me, and I’ve studied various events from that period. Therefore, I wrote A Bloody Hot Summer, a crime novel using some historical events as a background. The interwar years were the heyday of crime fiction, and that is why I set my novel during that period. While researching, I get to expand my knowledge regarding history, culture, art, language, and values of those times, which I add to the novel.

Trevor D'Silva Why did Trevor love this book?

In this book, a murder takes place in a manor house just like in my novel, but during Christmas time. There is a connection to a diamond mine in South Africa, and how that played a part in the murder of the patriarch of the family. Detective Hercule Poirot has to delve into the family’s past to connect the dots and determine the motive and the identity of the killer. For those who like murders set during Christmas time, this is a novel for you.

Book cover of The Mystery of Mercy Close

Nicola Moriarty Author Of You Need To Know

From my list on strong leads with mental illness or neurodiversity.

Why am I passionate about this?

Mental illness has been such a huge part of my life for so long now that it has become second nature for me to incorporate it into my work. After suffering postnatal depression, anxiety, and panic attacks, I’ve been on anti-depressants for 11 years and regularly see a wonderful psychologist. Recently, I added a psychiatrist into the mix who diagnosed me with ADHD, so now I’m learning to juggle ADHD meds alongside the antidepressants. I’ve always been passionate about talking and writing openly and honestly about my own personal experiences because if there is any chance that I can help someone else with my words, then I’m going to take it.

Nicola's book list on strong leads with mental illness or neurodiversity

Nicola Moriarty Why did Nicola love this book?

I adore every single word written by Marian Keyes, but the reason I’m including this book in this particular list is because the story centers around Helen Walsh, a private investigator who is severely depressed – and yet the book is not at all depressing to read. It’s clever, funny, and warm. So many of Helen’s thoughts and experiences rang true for me, which made it such a satisfying and validating read.

Chief among them is her charming but dodgy ex-boyfriend Jay Parker, who offers Helen a lucrative missing-persons case.

Book cover of Some Buried Caesar

Chuck Greaves Author Of The Chimera Club

From my list on crime fiction with a droll sense of humor.

Why am I passionate about this?

I’ve been a crime-fiction fanatic since devouring my big sister’s Nancy Drew mysteries as a pre-teen in 1960s Long Island. They proved a gateway drug to Sherlock Holmes, Nero Wolfe, and Phillip Marlowe, and eventually, after 25 years as an L.A. trial lawyer (with a client list that included Richard Pryor), to my own debut novel, Hush Money, in 2012. I’ve just published The Chimera Club, my seventh novel and the fourth installment in my award-winning Jack MacTaggart series of legal mysteries, and I’m delighted to share my views on crime fiction, and humor, with like-minded readers.  You can learn more about me, and about Jack, by visiting my website.

Chuck's book list on crime fiction with a droll sense of humor

Chuck Greaves Why did Chuck love this book?

Back in 2012, I had the honor of being a luncheon speaker at New York’s annual “Black Orchid Weekend” gathering of fans – and I mean fanatics – of Rex Stout’s iconic Nero Wolfe detective novels.  I was among my tribe, having cut my teeth on the Wolfe canon as a nerdy teenager to whom Stout’s books were a revelation: compact tales of crime and punishment starring a corpulent, agoraphobic gourmand and orchid fancier whose formidable (and unabashedly Sherlockian) powers of deduction were wielded from behind a desk in his brownstone on West 35th Street with the aid of a two-fisted Boswell named Archie Goodwin. While the yarns themselves are feasts, it’s Archie’s decidedly arch humor that provides the special sauce. Forced to choose, I’ll recommend Some Buried Caesar, Stout’s sixth Wolfe installment (of 33 novels and 39 novellas), originally published in 1939. It finds Wolfe in unfamiliar territory,…

An automobile breakdown strands Nero Wolfe and Archie in the middle of a private pasture—and a family feud over a prize bull. A restaurateur’s plan to buy the stud and barbecue it as a publicity stunt may be in poor taste, but it isn’t a crime . . . until Hickory Caesar Grindon, the soon-to-be-beefsteak bull, is found pawing the remains of a family scion. Wolfe is sure the idea that Caesar is the murderer is, well, pure bull. Now the great detective is on the horns of a dilemma as a veritable stampede of suspects—including a young lady Archie…


Book cover of Red Harvest

David Kruh Author Of Inseparable: An Alcatraz Escape Adventure

From my list on the 1920s with healthy skepticism of American values.

Why am I passionate about this?

I studied history in college and, after a few misspent years in broadcasting, worked in marketing and public relations for several companies. In my free time I wrote articles and books on historical events and people. A dozen years ago, on a trip to San Francisco and Alcatraz, I conceived of an idea for a novel. True to my background, it was based on a real historical event – the 1962 escape of three men in a raft from the prison. It wasn't until my mid-sixties when I felt ready to step out of my non-fiction comfort zone and write my first novel. Can't wait to start the next one.

David's book list on the 1920s with healthy skepticism of American values

David Kruh Why did David love this book?

It would be obscene to read this on a Kindle. This early Dashiell Hammett novel has to be read in paperback, the older a copy you can find, the better.

It has everything a great pulp novel should have; murder, crooked cops, gangs, and a rumpled too-honest-for-his-own-good hero. What I love about this book is how Hammett uses his own experience working for the Pinkerton Detective Agency (who were basically hired thugs) and a real historical event (a labor dispute in Montana that resulted in several deaths) to weave a solid crime novel.

What is this book about?

Detective-story master Dashiell Hammett gives us yet another unforgettable read in Red Harvest: When the last honest citizen of Poisonville was murdered, the Continental Op stayed on to punish the guilty--even if that meant taking on an entire town. Red Harvest is more than a superb crime novel: it is a classic exploration of corruption and violence in the American grain.

Debbie Chase Author Of The Mannequin Mystery

From my list on mystery books that keep you guessing.

Why am I passionate about this?

I have always been intrigued by missing persons. I wonder how their family copes with having no closure on the situation and how they can live wondering where their loved one is and whether they are dead or alive. I have read these recommended books many times to satisfy this craving. I enjoy a sense of the macabre even though the story may be about mundane everyday topics. This only adds to the sense of dread and wonder. I enjoy the intriguing twists and turns, keeping me on my toes and wanting more until the end. I hope you enjoy the books on this list as much as I have.

I recommend this book and the author’s fabulous writing, comprising of dread and humour (which I love), all rolled into one. Three separate case histories, interlinked, each littered with fabulous, memorable characters. Jackson Brodie, the Detective trying to solve the case, is one of the best, with brilliant detective skills and a haunting personal life.

An intriguing mix of family drama and mystery, giving it more depth than just an ordinary thriller. I have read this book many times, and it’s always new, never boring, and the ending is still a surprise.

Book cover of Bad Debts

Natalie Conyer Author Of Present Tense: A Schalk Lourens Mystery

From my list on crime featuring flawed detectives.

Why am I passionate about this?

I’ve always read and loved crime fiction – so much so I did a doctorate in it. I believe good crime fiction has the capacity to explore particular societies, places, and times in interesting and enjoyable ways. I also like crime fiction’s focus on character, and particularly in crime series which show a character evolving over time. That’s why I chose the theme of ‘flawed detective’ and that’s what I’m trying to do in my Schalk Lourens series, of which Present Tense is the first. I hope you enjoy it, and also the other books I’ve recommended here.

Natalie's book list on crime featuring flawed detectives

Natalie Conyer Why did Natalie love this book?

Peter Temple wasn’t just a good crime writer; he was a master storyteller. He’s my crime writing hero and I strongly recommend all his books, but as a ‘flawed detective’ it’s hard to go past his series starring Jack Irish and set in Melbourne, Australia. A former attorney, Irish went to pieces after the murder of his wife and now makes a living doing odd jobs like recovering debts. 

In Bad Debts, the first in the series, one of Irish’s clients calls him for help and by the time he answers, the client’s been murdered. Irish is emotionally damaged, an outsider. It’s hard-boiled crime, full of black humour, and featuring a wonderful array of Australian characters.

'Put simply, Temple is a master' John Harvey

'Great locations, hard-nosed dialogue and a twisting plot . . . super entertainment' Evening Standard

Jack Irish doesn't spook too easy. He's had guns pointed at him too many times - more often since he started hiring himself out as a debt collector - and he saves his nerves for the racetrack. So when he receives a phone message from an ex-client begging for help, he's inclined to ignore it. It's not an acquaintance…
