When the first Posadas County Mystery, Heartshot, published in 1991, Bill Gastner was the county Undersheriff. Over time Bill became Sheriff, then retired, and Robert Torrez took over the top spot. But what were Torrez's first days as a rookie officer like? Terrible!

It's 1986. Undersheriff Bill Gastner is enjoying his usual insomnia alone inside his old adobe when jolted by a horrendous noise. Dreading what he will find, he hastens to the nearby interstate exit where a violent crash has occurred. Not only is the vehicle that struck the support pillars totaled and the driver and a passenger crushed inside, a dead boy has been ejected.

As the appalled Gastner recognizes the youth and swings into action, the first deputy to join him at the scene is rookie Robert Torrez, the department's newest hire. Before Gastner can head him off, Torrez sees that the boy is his spirited younger brother. And the girl crushed inside the SUV is a younger sister. The driver of the Suburban, also dead, is the assistant District Attorney's teenaged son. Two local family tragedies.

A shaken couple reports that when the Suburban, careening at nearly 100 miles an hour, passed them on the interstate, activity inside hinted at its occupants' panic. Were the three dead kids running from someone-or something-rather than speeding? Further investigation reveals that a fourth teen should have been in the vehicle, but is now missing. Where had the four kids been? And why? It appears they'd lied to their parents.

Following his usual meticulous procedure, Gastner traces the vehicle's path to a remote canyon with attractive caves. The discovery he makes there balloons the case and introduces possible murder. Yet with a lack of witnesses hampering Sheriff Salcido, Gastner, Torrez, and other deputies, errors working the case can too easily be made.

Bill Gastner is my all-time favorite fictional cop! In Easy Errors, Havill goes back in time, making him the prime narrator.

Because Bill works in a "small town and rural" setting, rather than a monster sized city like Harry Bosch, my second favorite imaginary police officer, I'd much rather ride with Havill's character while solving a crime. This story has no evil criminal, just a mix of alcohol, guns, teenagers partying out in a rural setting, and some adults providing guns, alcohol, and targets for the kids.

Like myself, the Posadas under-sheriff savors driving the less traveled county secondary and ranch roads, just drifting along at slow speeds with the windows open, listening to the countryside. He knows most of the people in town. By now, over 20 books into the series, I've come to enjoy encountering them again. Readers not familiar with Havill's ongoing cast may find themselves meeting too many characters in just brief passages ... but, for this long-term fan, Easy Errors was a pleasant reunion.

His county, like mine, is dominated by rugged terrain, ranchers, BLM, and USFS, agencies not liked by local folks. Like the sheriffs in Havill's novels, I too attended county department head meetings, where it was politically essential to cope with sometimes ill-informed commissioners. I hope Mr Havill will tell more tales set during Bill's earlier years.

This story begins with a tragic car accident, and it is up the Undersheriff Bill Gastner and his team to uncover what led to it. This 22nd title in the series is a prequel about the first days of Robert Torrez’s life as a rookie cop. It follows Torrez and Gastner as they try to make sense of what happened. The author does an excellent job in this police procedural of gradually introducing bits of evidence and clues. Eventually, it all ties together, even things that seem at first to be unrelated. Though some the codes used by the cops may be unknown to readers, and some of the details about guns and bullets a bit tedious at times, Havill still manages to sustain a level of suspense that will keep the reader’s interest until the end.

The prequel in which we meet Sheriff Torrez on his first day on the job. And it’s certainly a day to remember as two of his siblings are killed in a motor vehicle accident. Undersheriff Bill Gastner leads the investigation. Three dead in the accident eventually culminates in five dead and three families devastated. Kids being kids or something else at play? The reader begins to suspect that all the investigating and attempts at linkage are going to end up in a rather mundane result- no drug trafficking or serial murders here- just routine police work with lots of emotional baggage. A parable of poor judgment with guns and alcohol.

So if the plot didn’t do it for me the setting and characters did. They are familiar friends and I could read about them painting an adobe or fixing fence. Wish this county and town were real so I could visit.

The latest book in this fine series is a prequel, covering the introduction to the sheriff's department in Posadas County of taciturn native son Robert Torrez, who will become such an important part of the team in later years. Undersheriff Bill Gastner narrates and describes his reaction to a horrific accident that kills three teenagers, and the reaction of Torrez, who is related to two of the dead. An accident caused by speed and alcohol--but what set the kids off on a 100-mile-an-hour race down the Interstate? Dedication and good police work can answer some of the questions, and Gastner's imaginative leaps and knowledge of the county can help a little more. Torrez proves his own cool head and work ethic along the way, but I did miss characters like Estelle, who joined the team later on.

Havill's pre-prequel details (and I do mean DETAILs) the first case on which Robert Torrez. Later, Torrez will become Posadas County Sheriff but, in this story of horrible accidents that claim the lives of 4 young people, Undersheriff Bill Gastner is in charge of training Torrez in the ways of police investigation. A compelling case but chock full of police codes, firearm specs, and other descriptive detail that some readers may find a drag on the plot. But the characters are compelling. For fans of the series, this may fill in some holes about a favorite character. For new readers, this slight but engaging police procedural may prompt investigation of other entries in the series.

As always, great book. Awesome author. Thanks Steven Havill for writing another excellent book. I love these flash-back / prequel books. I wish you would write more of them from back-in-the-day when Bill Gastner is the main character.

This is book 22 in Havill’s Posadas County (New Mexico) mystery series and is a prequel to the earlier books.
Demonstrating how reader opinion is more than background noise to crime fiction writers, Havill says this story sprang from a reader’s request for more information about Sheriff Robert Torrez’s early career. It’s a testament to how well Havill knows and understands his characters inside and out that he can reach back in time and conjure their younger selves.
Havill begins this book, narrated in the first person by Undersheriff Bill Gastner, with Gastner relaxing one Wednesday night (with a book!), interrupted in the third paragraph with “the distant shriek of tires tearing rubber and the loud, dull whump that followed.” A motor vehicle has crashed disastrously somewhere nearby, so Gastner alerts the sheriff’s dispatcher and sets out to find the source of the noise.
It isn’t pretty.
What follows over the next few days is the meticulous reconstruction of events that led to this tragedy. You might think an auto crash could not sustain investigative—and reader—attention for an entire novel, but Havill’s skill lies in making this police procedural absolutely riveting. It proves that a crime story doesn’t have to trot out a demented serial killer or imperil the US President and all of Congress in order to have stakes worth caring about.
Each of Havill’s characters is intrinsically interesting, and it’s equally interesting to see how they work together as a team, which includes working around some spotty (and humorous) assistance from the police dispatchers.
The care that Havill takes in reconstructing the crime and establishing the officers’ logic in developing every last bit of evidence holds until near the book’s end, when the author has the prosecutor, speaking before the grand jury, claim a type of evidence the authorities do not actually possess. While the grand jury might reach the same decision with or without this information, its decision is based on a totality of evidence, and the total is flawed. In a novel so thoroughly grounded in the step-by-step accretion of facts, this slip-up is jarring, and the book’s title, Easy Errors, turns ironic.
Still, the rest of the book is so strong, it isn’t enough to discourage me from wanting to read more Posadas County mysteries. As a fan of the Longmire tv series, based on Craig Johnson’s books, I warmed to this one immediately.

"Easy Errors" is a prequel in the Posadas County mysteries featuring Bill Gastner. As the series progresses, Gastner eventually retires as sheriff and Robert Torrez takes over that position. This prequel describes the terrible events that occurred on Torrez's first day as a rookie officer when the first incident he must investigate involves members of his own family.

I am so glad I came across this series a couple of years ago. It has quickly become one of my favorites. I haven't read all of the prior books, yet, but I've enjoyed all I have read. I love the southwestern U.S. setting, the careful plotting, and realistic and interesting characters. I especially like the character of Gastner who is tough on crime but soft towards those he cares about. In prior books I've read, I've come to respect Torrez's intelligence and calm demeanor.

Since this book is a prequel, instead of reading the backstory of various characters in the series, the reader gets to see some of that history as it unfolded at the time. Longtime readers will like this glimpse into the past and it's a perfect introduction to Posadas County for new readers. The case is heartbreaking and the investigation kept my interest from beginning to end.

The only downside is that Estelle Guzman-Reyes is just a teen at the time this book takes place, so she obviously doesn't play a part in the book. This is to be expected, but in the new books, the friendship and rapport between Bill and Estelle are one of the things I love about the series. However, the other characters and how they work together to solve a tragic case help to fill the gaps.

I received this book from NetGalley, through the courtesy of Poisoned Pen Press. The book was provided to me in exchange for an honest review.

I don’t know why I didn’t just go ahead and rate this five stars. We’ll go 4.49 and reluctantly round down.

The author takes you back to 1986 and Robert Torrez’s first day on the job. You don’t have to have read any other book in the series to enjoy this. It’s kind of a prequel to the prequel.

Undersheriff Bill Gastner is comfortably in his house the night he hears the horrific crash on a nearby interstate. With dread, he approaches the crash scene as does rookie Robert Torrez who technically won’t start his first day on the job until the following morning. He’s riding with another officer just to get a feel for the community before he is official.

Inside the crushed SUV is a group of teens, some of whom had been drinking, and all of whom were dead. Two of the kids were Torrez’s brother and sister. Gastner can’t block the view before Torrez sees who died in the SUV.

As the investigation proceeds, they learn that a fourth teen should have been in the vehicle but wasn’t. Initially, they can’t find her. You can read this to determine what happened.

You encounter some grand jury courtroom dialogue in here that will keep you reading, and the investigation broadens to include a small cadre of drunken hunters. You’ll learn cool stuff about ballistics and the various tests they ran in 1986 to determine whether bullets match in several instances.

I enjoyed this, and it’s wonderful to see a long-running series that remains fresh, exciting, and entertaining.

#22 in the Posadas County mystery series. Some readers classify Posadas as two series but the setting is the same and the characters are the same except that time creates promotions, deaths and retirements. This 2017 episode is a prequel to all of the prior books and starts with the day current sheriff Robert Torrez arrived on the job as a rookie officer in 1986. A treat for series fans to return to Bill Gastner as Undersheriff as see the start of laconic Torrez' career.

A prequel set in 1986. Laconic Bill Gastner was still undersheriff and working with Robert Torrez, then a rookie. The day after a horrific automobile accident kills three local teens on the interstate, the body of one of their friends, Darlene Spencer, is discovered in a canyon. Although the girl is miles from the scene of the accident and has a bullet hole in her head, Gastner and Torrez are convinced the two incidents are related.

I really like the Steven Havill - Posadas Mysteries series of books. If you're following the series, Easy Errors is a prequel - its the story of how (current sheriff) Bobby Torrez joins the force. Its an interesting story - its told from the point of view of Undersheriff, Bill Gastner. This is a full police procedural - you follow the story from the first report, through the investigation, which includes ballistic evidence, photos and crime scene drawings - right up through the legal part of crime solving. The action is slightly below what is usually found in the Posadas Mysteries but the story holds together and (in my opinion) only fizzles slightly at the end. If you're not following the series you'll love the attention to detail in the book - - its a mystery that will keep you turning pages.

This was definitely a police procedural. The author walked us through the painful and meticulous gathering of every piece of evidence. Then, we got the joy of walking through it, again, with the grand jury scenes. All of that, and we got stuck with an unsatisfying conclusion. I feel cheated.

Actually, it's a bit of a miracle that I finished reading this book, at all. I really was put off early by the blatant racism (negative comments about Mexicans). I only finished because the book is for a discussion group that meets at my house.

Despite the bad beginning, the book improved somewhat. It bogged down with details about gun calibers and distances. I really didn't need to know how they set up the department's ballistics test setup.

I am not motivated to read any other books in the series.

Steven Havill has done it again. EASY ERRORS is his 22nd book in the Posadas County Mysteries. In EASY ERRORS, we are taken back to the day when Robert Torrez, having finished the Police Academy, walks into the Sheriff's Office, for his first day. Everybody in Posadas knows every one else (much like it is where I live in New Mexico), and Torrez comes from a big family. Within 12 hours of beginning his job, Torrez's mind has been shattered.
So as not to give out any spoilers, I will stop here. I love these books and all the people in them. This is the second book that Havill has written, that has reached back to tell about the story of various people when they first came to work at the Posadas County Sheriff's Office.

Set in 1986, Bill Gastner is under sheriff of Posadas County and Robert Torrez is about to start his first day on the job. They are called out to the scene of a car crash in which three teens have been killed, two of them definitely under the influence of alcohol. What follows is a meticulous procedural that reveals a more complex situation than anyone could have anticipated. Whether adults or children, mixing alcohol and guns makes it easy to fall into all-too-human errors in judgment (calling to mind Tony Hillerman’s title “Coyote Waits”). Masterfully written, and the narration by reader Rusty Nelson is, as usual, superb. However, I wish the story had culminated in more of a sense of justice rather than just desolation.

Despite the fact that this is the 22nd book, it's actually the first (does that make sense?) because it's set in 1986 and is the "origin story" for Bill Gastner and Robert Torres, who are the linchpins of the series. The mystery was less important to me than the character studies and the wonderfully atmospheric setting. This is a fairly basic procedural, with law enforcement trying to find out what led to the deaths of three teens and the disappearance of another. That said, it's also a page turner. Thanks to Netgalley for the ARC. This is for fans of Havill or for those looking for a new series.

"Easy Errors (2017) Although this was written in 2017 it happens at the very beginning of the Bill Gastner series so it is the prequel to the prequel." These are notes that I found curiously from Wikipedia about this book.

When I first started reading this book. I was totally lost, then I found the above notes, then it all made sense. This book should be classed differently.
But that's okay, I still enjoyed the book. Bill Gastner is an awesome character. I have loved all the books that I have read from author Steven F. Havill.

I am so glad I choose this book! I wanted something between Longmire and Johnstone. The review for this book made me think it would fit the bill. Plus, despite being #22 in the series, it takes us back to the beginning for the main character. Bingo! I am totally in love with this author - not him personally, his writing style, but any avid reader knows what I mean! I was totally unprepared for how much I enjoyed this book. While the setting is not all the different from my other beloved Westerns, the characters are certainly unique. It took me a while to figure out the 'who done it and how' but even once I did, Havill kept spinning it out in such a way that I was in awe. While I am not sure I have bonded with our soon-to-be Undersheriff, I am indeed curious about the other books in this series. Well played, Mr. Havill!

I don't know how these books have been around for so long and I never heard about them until recently. I check them out of the library for my dad since it's hard for him to get around and he likes to read. He reads them and tells me he likes them but there's not enough "action" in them to keep an older man interested. He would like it if they were a little more "rough and tumble" in his opinion. So, just passing along what he said.

One of Havill's best. An engaging mystery

This book is a little different but in a good way. Four teens are dead and just why seems out of reach until good detective work eventually reveals the answers. You assume dark intent from some one who acted nefariously but something else was at work. Is it murder or something else? I enjoyed this book a lot. Like all mysteries, things wrap up at the end but this one is believable and credible. A very good read.

Well composed backstory/prequel to the Posadas series. Includes particulars about crime scene investigation in preparation for an eventual court presentation. Sloppy work equals perp going free. Having heard the author discuss his research methods, I can almost imagine his happening upon some of these facts and gleefully including them in this work.

I enjoyed this step back into time, although the ending was both anti-climatic and predictable. It was interesting to see how taciturn Bobby Torrez got started and how Bill Gastner performed when he was much younger. The pace is good and the writing sharp.

This may be the 12th in the series, but it is first chronologically. But I am not sure it makes a difference when you read it, as long as you realize this. Robert Torres is a rookie, and Estelle still a school student, and not part of the story. I am happy this series continues in either direction!

The story was fine, the last chapter was wimpy - as if he didn't know how to end the book.
The author and his editors obviously never met a homophone they didn't like.
I'll try a couple more and see if they're any better.

Did I miss something? Gastner testifies before the grand jury that their blood alcohol content was 1.1, 1.9, and 1.8 on the night of the shooting. How did they test them? They didn’t get them until a few days after the shooting!

A prequel to the series, Easy Errors is the story of Robert Torrez’s beginning as a policeman in Posados County. Told by my old favorite sheriff Bill Gastner, the tragic deaths of 4 kids is a mystery to be unravelled.

Good police procedural. It explains the introduction of Robert Torrez to the Posadas sheriffs office. Much less family than usual which is good.
