Book cover of Mindhunter: Inside the FBI's Elite Serial Crime Unit

Craig McGuire Author Of Empire City Under Siege

From my list on appreciating different aspects of law enforcement.

Why am I passionate about this?

I selected the five works below, as each highlights different themes explored in my latest work. Taken together, this collection delivers a well-rounded, multi-dimensional view into a world that is often simplified in popular culture but far more complex, courageous, and human than most people realize. These books illuminate different facets of law enforcement—from the raw courage required in moments of crisis to the resourcefulness demanded in prolonged investigations. 

Above all, these works stand out for their honesty and realism, revealing both the triumphs and the tolls of a career committed to protecting others. Together, they provide readers with a deeper appreciation of the people, the pressures, and the evolving landscape of modern law enforcement.

Craig McGuire Why Craig loves this book

Thematically, my book explores the evolution of the FBI during its most transformative decades. This exceptional work takes us deeper into one area where the FBI can bring to bear remarkable capabilities unlike any other agency: the introduction of Criminal Profiling. 

Douglas delivers a rare insider’s account as one of the FBI’s original profilers in ways that are as informative as they are provocative, all within the harrowing high-stakes context of pursuing some of the most heinous and ultra-violent criminals imaginable. 

Douglas wisely balances this complex, historical, technique-driven accounting with narrative portrayals rife with real consequences that this select group of trailblazing investigators absorbed due to such intimate immersion pursuing these worst-of-the-worst criminal minds. The sheer emotional weight and toll on them are stunning, heightening the sense of debt we as a society owe to them for their invaluable service. 

These sacrifices underscore the reality that protecting and serving for…

Book cover of Killers of the Flower Moon: The Osage Murders and the Birth of the FBI

Chris Kelsey Author Of Where the Hurt Is

From my list on no difference between Oklahoma and Texas.

Why am I passionate about this?

As a child in Oklahoma and Texas during the 1960s and 1970s, I remember being told two things: “Oklahoma is OK” and “The Eyes of Texas” were upon me. My grandparents and great-grandparents helped carve the new state of Oklahoma out of nothing within the span of only a few years. For a long time, I accepted the party line, but as an adult, I realized I wasn’t—the picture was incomplete. Underneath the inspiring tales of grit and heroism was something darker. That’s a big part of what my writing is about.

Chris' book list on no difference between Oklahoma and Texas

Chris Kelsey Why Chris loves this book

My great-grandfather came to Oklahoma during the Run of 1893, the fourth of the five land runs that officially opened the state to white settlement. As a kid, I was spoon-fed, uplifting stories about the state’s founding while being kept in the dark about its bleaker episodes.

One of them was the theft by white men in the 1920s of oil rights owned by the Osage people of northern Oklahoma. A story of murder, theft, and betrayal, Grann’s book made me angry about the lies I was told as a child, not to mention the injustice still shownto  Oklahoma’s indigenous population.

Why should I read it?

24 authors picked Killers of the Flower Moon as one of their favorite books, and they share why you should read it.

What is this book about?

In the 1920s, the richest people per capita in the world were members of the Osage Indian nation in Oklahoma. After oil was discovered beneath their land, they rode in chauffeured automobiles, built mansions and sent their children to study in Europe.

Then, one by one, the Osage began to be killed off. As the death toll climbed, the FBI took up the case. But the bureau badly bungled the investigation. In desperation, its young director, J. Edgar Hoover, turned to a former Texas Ranger named Tom White to unravel the mystery. Together with the Osage he and his undercover…


Book cover of Donnie Brasco: My Undercover Life in the Mafia - A True Story by FBI Agent Joseph D. Pistone

Mark Wish Author Of Necessary Deeds

From my list on gruesome murders and genuine love.

Why am I passionate about this?

I had the passion to write Necessary Deeds because: 1) as someone who'd spent 20+ years writing novels, dealing with untrustworthy literary agents, and book-doctoring other writers’ novels in order to pay rent, I'd come to know betrayal (“best friend” writers who stole drafts of mine and called them their own, novelists who backstabbed me after I helped them land agents and book contracts, and so on); 2) like many people who lived through the drug-and-alcohol-laced Eighties, I had a long relationship with someone that ended because they cheated on me. So I never doubted that, as I wrote Necessary Deeds, my heart knew well what motivated its characters.

Mark's book list on gruesome murders and genuine love

Mark Wish Why Mark loves this book

In this case, I saw the film before I read the book, and if I’m going to call myself an honest man, I’d have to say I enjoyed the film more than the book.

Still, the book struck me as a great read because it embraced and portrayed the extraordinary amount of tension an undercover agent deals with 24/7. I mean, when you’re trying to make an arrest undercover, you’re two people at the same time, but you’d better not mess up and let anyone know you are or it’s game over—and very probably, bang-bang, pal, you’re history.

Add to that being undercover for the FBI and you’re guaranteed a high-stakes conundrum. Which is to say, after reading this book, how could I not have had my book’s character working undercover for what he and his partner Jonas refer to as “the Bureau”?

What is this book about?

In 1978, the US government waged a war against organised crime. One man was left behind the lines. From 1976 until 1981, Special Agent Pistone lived undercover with the Mafia. Only able to visit his young family once every few months, Pistone - under the alias Donnie Brasco - ate, drank, partied, worked and sometimes killed with the wiseguys. He got so close that his Mafia partner, Lefty Ruggiero, asked him to officiate as best man at his wedding. Pistone's eventual testimony, in such spectacular prosecutions as 'the Pizza Connection' and 'the Mafia Commission' resulted in more than 200 indictments…

Book cover of Five Presidents: My Extraordinary Journey with Eisenhower, Kennedy, Johnson, Nixon, and Ford

Paul Letersky Author Of The Director: My Years Assisting J. Edgar Hoover

From my list on American history, scandal and corruption.

Why am I passionate about this?

My entire fifty-year professional life has been dedicated to law and order, investigating crime and corruption at its highest levels in government and the private sector. I’ve worked on hundreds of cases together with local, state, and federal law enforcement. Also, internationally with Scotland Yard, GSG9, New South Wales, and the Soviet KGB. There is deep gratification in taking the “bad” guy off the street, protecting those who cannot protect themselves. I have a law degree and am an Adjunct Professor of Constitutional Law looking forward in contributing to winning the battle of “equality for all” in the justice system.

Clint Hill’s legacy is his courageous action in the presidential motorcade during the JFK assassination. His career and mine overlapped. We address events occurring during the same era but from different perspectives. His as a Secret Service Agent on protective details and mine as an FBI Agent investigating criminal cases and personally assisting J. Edgar Hoover who worked under eight presidents and sixteen attorneys general. Hill had to be politically correct under all circumstances while I could get away with a blurred PC often to solve a criminal case. At times, our observance of historic events varied—but again we viewed them relative to our positions.

Even if Retired NYPD Detective Thomas Dades didn’t introduce me to my co-author Anthony Nelson, I’d still highly recommend this gripping, behind-the-scenes account of one of the most shocking and consequential corruption investigations in NYPD history. 

This work dives into the day-to-day work of putting together a case against two of the most corrupt police officers in New York City history: Louis Eppolito and Stephen Caracappa, a.k.a. the “Mafia Cops.” 

It is the compelling story you can’t help but marvel at the investigative tenacity, political crosswinds navigated by prosecutors and investigators, personal costs and professional risks, and the sheer amount of time and effort needed to deliver justice. 

Friends of the Family is different from many law enforcement books in that Dades and Vecchione are so honest and open about their investigative odyssey, and along for the ride, the reader begins to appreciate the humanity of these good cops and…

Lois Winston Author Of Guilty as Framed

From my list on cozy & amateur sleuth mysteries when you need a laugh.

Why am I passionate about this?

I started out my writing career in romance and romantic suspense but discovered my humor gene when I wrote my first chick lit novel. Who knew I could write humor? Certainly not me! I bungle every joke I’ve ever tried to tell. But suddenly humor was flowing from my fingertips onto my computer screen. Seeing this new side to my writing, my agent suggested I try my hand at a humorous cozy mystery. Suddenly I found my true calling. I left the world of romance behind and settled into the world of murder and mayhem, complete with a large dollop of laughter.

When twenty-six-year-old Lady Philomena Dunbridge solves a murder that has stymied the police, she scandalizes Edwardian England. Rather than lead a dowager’s life, she escapes to America—and immediately stumbles upon another murder in need of solving. I absolutely love Lady Phil’s unique outlook on life, which had me chuckling from chapter to chapter. The verbal sparring between her and her butler, the detective assigned to the case, and the mysterious Mr. X often made me shout, “You go, girl!” And she not only excels at dropping perfect bon mots, but she goes about unraveling whodunnit with absolute panache.

Why am I passionate about this?

Some of us are confronted, amid life, with the need to look at ourselves and to change. It’s usually a question of survival. Do I want to live? Better stop this, better start that. I consider myself fortunate to have been forced down this path. So, who am I, really? Will I double down on my past mistakes, or can I change up and make some new ones? I love stories of the pain that precedes growth, redemption, and freedom that comes with it. Here are five of my favorite novels about recognizing what you are and becoming something new.

This is how good Mosley is: I couldn’t escape the feeling that I knew his protagonist the whole time I was reading this. I swear I had met the guy somewhere. I walked those same Brooklyn streets, and Mosley’s portrait of them was strong enough and real enough to make me miss the place, even though Brooklyn is overrun with lawyers and stock brokers these days.

And Mosley’s secondary characters are just as real, and if you screw up, you just might meet some of them. One last thing: when Mosley writes about race, he does it in lowercase. That way, the story sneaks under your defenses and hits you much harder than if it was all in caps. Walter Mosley is not just a writer; he’s an artist.

Book cover of Filthy Rich: The Shocking True Story of Jeffrey Epstein - The Billionaire's Sex Scandal

Rob St. Clair Author Of Saving Stacy: The Untold Story of the Moody Massacre

From my list on true crime tragedies.

Why am I passionate about this?

Working as a prosecutor, trial lawyer for defendants, and as a magistrate, I’m always bothered by the misconception most people have of our criminal justice system. Unfortunately, cops are crooked, judges are corrupt, and witnesses lie on the stand. Not everyone, not every day, but more often than you would ever imagine. I write true crime books about cases where the underlying focus is on officials who are incompetent, derelict in their duties, or simply downright corrupt. The cases are always suspenseful, but justice is rarely served, and both the defendant and the public are the ones who lose.

There’s a reason James Patterson is a popular, best-selling author. His books are well-written, entertaining, and – when he turns his pen to nonfiction – informative.

Jeffrey Epstein rose from humble origins into the New York City and Palm Beach elite. A college dropout with an instinct for numbers – and for people – Epstein amassed his wealth through a combination of access and skill. But even after he had it all, Epstein wanted more. That unceasing desire – and especially a taste for underage girls – resulted in sexual abuse charges, to which he pleaded guilty and received a shockingly lenient sentence.

Included in Filthy Rich are police interviews with girls who alleged sexual abuse by Epstein, details of the investigation against him, and a new introduction with up-to-the-minute developments on the case, including Epstein's death by suicide.

Why am I passionate about this?

Writing is my life. As a child I wrote poems, scripts, and short stories. A couple of decades, a BCALA literary award, and a three-book deal later, my wild imagination has grown into a passion for exposing the truth. In 2020, a third of the 300,000 missing women in the United States were Black, and in that same year, I was almost a victim of human trafficking myself. With this second chance, I write to bring awareness and attention to women who cannot speak for themselves. I write to shed light on the truth and these five books have helped me on my journey.

JJ Savaunt Why JJ loves this book

One of my favorite reads of all time is Abuse of Power because it gave birth to my inner conspiracy theorist. When a routine check turns violent, a reputable police officer does the unthinkable, and even worse, his brothers in blue follow suit, leaving the heroine trapped between telling the truth or staying alive. From this novel I learned if you want the truth out of someone, you have to ask the right questions, probing questions that require a specific answer other than yes or no, but even more than that, listen for inconsistencies.

From my list on historical female protagonists in unusual jobs.

Why am I passionate about this?

As a former Human Resources executive I’m fascinated by the history of women in the workforce, especially in jobs that have traditionally been held by men. I was first drawn into the topic as a writer of WWII novels. Through memoirs, autobiographies, and oral history interviews I learned firsthand about women who entered the workforce to take the place of men who were serving in combat or the defense industry. In an effort to spotlight the women of this era as well as those who have gone before, many of my protagonists hold unusual jobs such as spy, war correspondent, pilot, doctor, restaurant owner, and gold miner.

Having worked for a jewelry designer in the Washington, DC area, The Gem Thief caught my eye. The story took me back to my days in the shop (good memories!), and the author has obviously done her research, because her accuracy is impeccable. I liked all of the characters, but I bonded with one of the secondary characters so much that I felt we could be friends in “real life.” I’ve been to New York City often, so I also enjoyed revisiting the city. The book was both comfortable because of all the associations to “past lives,” and exciting as I turned pages wondering what would happen next.
