Manny Rivera #10

Cast A Cold Eye

Rate this book
RUSTY RANDALL, a young man following his dream of becoming the author of an important work of history, sets out to learn and record the past events which took place on the Whitmire Ranch since its founding in 1890. The ranch’s history of serving as a refuge for outlaws like Butch Cassidy who were on the run in the remote backcountry of the Utah-Colorado border, makes the project interesting and motivates Rusty to work hard every day. Four months into his research, his body is found in a remote part of the LaSal Mountains, a small caliber bullet lodged in his brain. Were there activities going on at the ranch that Rusty would have been better off not digging into? Or was his murder related to something else altogether? Deputy Sheriff Manny Rivera is assigned the case and sets out to learn the motive for the killing, and through that, identify the perpetrator.

I like the Manny Rivera books and this one was a good read. Manny is a deputy sheriff in Moab Utah, which is beautiful, rugged red rock country - and he loves the area and his job. I believe I've read 2 or 3 of the Rivera books and in no certain order. I didn't realize this was book 10 when I began reading it and it works as a standalone as well as a series book. Manny is a really good guy who cares about people and he cares about doing a good job. In this book 10, he is recently married to Gloria and very happy about it. That is a bit of side story, but a happy part for him. The story is about things that happened at the Sullivan/Whitmire Ranch over the past hundred or so years, along with the murder of a young man who had been working on writing a history of that ranch. There are a lot of ins and outs and happenings that keep the story fluid and interesting. Manny works at solving the case(s) and we meet some interesting characters along the way. This is a good, clean book and I enjoyed it.

Another intelligent and likeable Deputy Manny Rivera tale set in Moab, Utah. The body of a young writer is found in the back seat of his Jeep. The murder may be tied to his interest in the history of a local ranch, once a hideaway for Butch Cassidy, the Sundance Kid, and other members of the Wild Bunch. It’s a solid premise for a mystery that grows steadily more complex and layered. Rivera himself is now, finally, married and the new wife even aids his investigation of the crime. But Manny remains the low-key star of Rich Curtin’s long-running series.

Rich Curtin never disappoints

I feel like a visit the high desert country in every book. Manny Rivera is a comfortable blend of lawman, friend and philosopher. I learn something new while reading each book and this one even included a practical tip for my sheep loving brother to get a llama to tend the herd.

The murder of Rusty Randall, a young man who wants to write a book about a historic Utah ranch once a refuge for outlaws, comes as a shock to those who have befriended him as he researched his project. They can offer Deputy Sheriff Manny Rivera no obvious motive for the crime.
The newly married lawman is equally puzzled at first. The victim seemed to share Manny's love for the high desert country, his project harmed no one, and he had made many friends and no apparent enemies while doing his research.
As Rivera interviews people who'd encountered the victim every potential motive seems to fizzle like chaff in a desert wind. The only consistent factors seem to be artifacts Randall found related to a young woman who mysteriously disappeared in the area of the ranch decades earlier. Can the two crimes be related? If so, how?
As Rivera concentrates on the mystery he is also worried about an upcoming election which he fears the current sheriff may lose to her predecessor, a man Manny despises and vows never to work under again. He has decided to resign from his job if the election goes the wrong way, though it would mean leaving the Moab region he loves and also forcing his bride to give up a position she has just accepted.
There are plenty of twists and turns before Manny, good detective that he is unravels the many skeins and solves not just the murder but the earlier crime as well.
I've now read six of the 10 books in the series and have become a fan of Rich Curtin who spins intriguing stories with realistic characters and vivid descriptions of the high desert country he appears to love as much as does his character. In many ways, this series reminds me of all I love in the Navajo country books of the late Tony Hillerman.

The latest novel in the Manny Rivera series by Rich Curtin. I have enjoyed these books and have enjoyed the progression of his writing from the first to this last one. Hopefully, Rich Curtin will be continuing the series soon.

In this story, Manny finds himself assigned to a murder case of a young man found shot in the back of his jeep parked at a remote location next to a small lake in the mountains. The murder clearly wasn't driven by robbery as his wallet was intact and the keys to the jeep still in the ignition. Why the young man was killed was a mystery but why he was even in the region around Moab was another. When Manny finds a connection between the young man and a ranch in the mountains, the case takes on a historical bent for the region.

As Manny struggles with making sense of the murder case, he is informed of a missing persons case going back 30 years. As he investigates both cases separately, he begins to wonder if the two cases could possibly be somehow connected. Even after finding evidence of some connection, he struggles with understanding how they really could be connected. And struggles even more with how to prove any connection.

These are investigation stories with little action in any of them. In that regard, these stories are refreshing. Rich Curtin has developed interesting characters and grown them with personal experiences which add to the stories. Reading the growth of Manny Rivera in Moab and in the Sheriff's department is part of the enjoyment for me in this series.

Cast a Cold Eye may be my favorite Manny Rivera book yet. Manny, fresh off his honeymoon with Gloria is called to investigate the murder of a young man who was planning to write a historical novel about a historical Moab area ranch.

Those who knew them liked Rusty Randall and none could figure out why anyone would want to kill him. Manny is at a loss to figure out a motive for the murder. Then he learns Rusty had found a cigarette case while exploring the ranch with his metal detector. It had been buried for a long time and the name engraved was that of a woman who had been missing for almost thirty years.

In the meantime, his boss, Sheriff Louise Anderson is running for re-election and her opponent is none other than Rivera’s nemesis, former sheriff Denny Campbell. Campbell is leading in the poles and if elected, Manny knows he’ll have to resign. That puts him in a dilemma since Gloria has just relocated to Moab.

It’s Gloria who discovers something that helps Manny solve the case. I don’t post spoilers, so I’ll leave it at that.

Cast a Cold Eye blends modern-day and history. The only thing I had an issue with was the easy confession of the killer, but it didn’t distract from the story.

This is the tenth Manny Rivera book, and I’m hoping it won’t be the last.

Another great mystery starring Manny Rivera, a deputy sherrif in Moab, Utah. The body of a young man was found in a truck. Because he was killed by a revolver shot to the head, Manny was assigned to solve this case. It was important to the sherrif that the case be solved quickly as she was in the middle of her reelection campaign. Manny too had a lot invested in solving the case because he didn't want the Sherrif's rival to win the election. The case became more complicated as it appeared to be connected to a 30-year-old missing person case. As with the other books in the series, it was a treat following Manny as he works his way through the few clues to the eventual solution. All of the characters are well-realized and Manny's personal life is as important to the story as the main mystery. Plus, like the Tony (and Ann) Hillerman mysteries, the setting of the story is almost another character. Southeastern Utah is such a beautiful place with a rich history. Having lived for many years on the Western Slope of Colorado, I understand the author's obvious appreciation for this high dessert area.

Another good addition to the Manny Rivera series. Manny is a deputy sheriff in Moab Utah. He is a down to earth, married, likable character who genuinely cares about the Moab region and the folks that reside there. The story is set in the region of the Sullivan/Whitmire Ranch which has a rich history including being a hideaway for gangsters of the past including Butch Cassidy and the Sundance Kid. The story revolves around the murder of Rusty Randall, an amateur historian who is collecting information for a book about the Ranch.
The story moves along well and includes some great descriptions of the Moab region. As the plot unfolds there is a connection to a 30-year old missing person case. There are some entertaining twists and turns to the story and everything comes together well in the end. My only criticism is that the author introduces a number of potential side stories that are not well developed. Hence, the 4 instead of 5 star rating. However, I enjoyed the trip to the American Southwest and the clean, interesting story line. I have enjoyed all of the previous books in the series and recommend the whole series. Happy reading!

Enjoyable western murder mystery set in Utah

I’m a crime fiction fan who occasionally reads new-to-me authors, so I chose one of author Rich Curtin’s western mysteries. I enjoyed following Deputy Sheriff Manny Rivera as he investigates the murder of a young historical writer and researcher. Rivera also discovers a thirty-year-old grave of a possible murder victim. Another subplot: the looming sheriff’s election featuring a smarmy candidate with a rich supporter.

There are a lot of suspects for the contemporary murder, plus several for the old murder, but Rivera is a methodical, level-headed, “no drama” detective. The red herrings are very good, and the ending satisfying—although a change in one character was difficult to believe.

I docked a star for the many word-walls of information about the gorgeous scenery, various historic sites, and much oral history. If I were a reader of Western Fiction, I probably would’ve loved reading it all.

A Cold Eye and a Warm Heart

Rich Curtin’s Manny Rivera mysteries are intriguing, realistic, and to me, inspiring on several levels. The complexity of human lives, and motivations, how entangled they are, largely creates the mystery. Descriptions of people and situations such as a competent, hard working person potentially having to leave a well loved job due to a an incompetent, unethical supervisor are realistic. So are the effects of love lost, through death or abandonment. This book inspired me to want to get out in nature more, to wait to make up my mind about people and situations until I know more of the facts, and by Manny’s good hearted character as written by Curtin to renew my efforts to be a good, or at least a decent, person. Descriptions of the land, sky, flora and fauna of the 4-corners area make me specifically want to go there. I’ve heard about Moab for years from friends, but this book makes me want to GO there.

In 1890, newly arrived Irish immigrant Sean O’Sullivan started a ranch in a remote corner of Utah near the Colorado border. Later, the ranch was acquired by Tom Whitmore and his wife. They discontinued hunting, closed the lucrative uranium mines, and restricted timber felling to what was needed for ranch construction. Young historian Rusty Randall has become fascinated by the colorful history of the ranch and is in the midst of researching a book when his body is found in the back of his jeep dead from a bullet wound. In the course of the investigation, Deputy Sheriff Manny Rivera also becomes fascinated by the history and setting of the ranch. The great beauty of the story is the author’s wonderful descriptions of the high desert country. I did have a little confusion working out the chronology of the ranch and the publication of Yeat’s poem.

Manny Rivera settles down

Cast a Cold Eye brings Deputy Rivera back to investigate another baffling murder case in the beautiful Red Rock country of Moab. While good as a stand alone story, followers of the Manny Rivera series will enjoy the continuing stories of many characters introduced in previous books. The investigation is thoughtful & thorough as Manny cannot leave any “loose ends” out when concluding his investigations. Many twists & turns & even political pressure made this case very interesting. As usual, Manny’s insights into human nature and his pragmatic, ethical approach will delight readers. Newlywed Rivera represents a maturing side to the man respected by many. I am hoping the series will continue!

Love High Desert

I miss the west, especially SE Utah. Rich Curtin has a way to place you right inside his locations. With what little information Manny has available to him, you wonder how the murder mystery could ever be solved

The clues slowly evolve to not only the original vase but another death and a few other lesser law infractions. A great tale with wonderful complimentary characters.

I realize the story is fictional but as you grow deeper into the story it becomes real. I appreciate the author did not resort to graphic violence, sexual content or foul language to entice a reading audience.

Enjoy the reading adventure. All 10 of the Manny Rivera series books are just as good.

Another good Rich Curtin book. As with earlier books in the series, this one has a strong sense of place in the red rocks of Utah.
The author does a good job of keeping you guessing until near the end.
My only large complaint is about how quickly the confessions came. I'd have expected more of a fight from the bad people involved. There was a lot of, "You've got me, let me spill the beans."
I also think that Deputy Sheriff Rivera ought to hold his cards closer to his vest, but he likes to tell everybody just about everything he knows about the case so far.

At last Manny is married and enjoying married life. And Gloria was a big help to him in this case. There is a murder and an accidental death from years earlier that gets covered up--and it all gets very complicated and involved. I have read book 7 and book 10 in the last two days--having read 8 and 9 previously. I hope there will be a Book 11. For a while it looked as if Manny would resign if the wrong person won election as sheriff, but that gets resolved and the series can go on--right in Moab.

The 10th book in this series did not disappoint. Rich reminded the readers of the characters whom Manny interacted with in his past books in a way that brought us up to date with where book9 left off. I visited Moab 3 years ago and became familiar the the landscape, highways, and town which are the settings in the books. That’s what initially drew me to the first book of the series. Cast a Cold Eye was hard to put down and kept me in suspense until the case was solved. Rich, I hope you are continuing to write more stories of these adventures of Manny Rivera! Great job!

5* Mystery and history combined.

Back on duty after marrying Gloria Valdez, Deputy Sheriff Manny Rivera's first case is the investigation of the murder of a young man who was writing a history of Moab when the West was truly Wild.

No fancy car chases or gun fights, just Manny's steady search to solve his case which becomes more and more complex.

Great reading of past murders and present political intrigue set in Utah.

Thoroughly enjoyed reading book 10 and hoping that the series continues.

Meandering down a colorful path to a satisfying end

Have patience. The book starts slowly with what seems like excessive attention to the details of the surroundings and appearances, but it draws you into its world and its inhabitants and gathers your interest. Before you’re aware of how it happened you’re tightly enfolded in its warm hold and it becomes hard to put down. The mystery involved is slowly resolved as layer after layer is peeled back and a satisfying ending is softly laid in place. Well worth the journey. Highly recommended.

Wasn’t a mystery at all for me SPOILER

It’s silly but I estimate about 98% of the time I read a murder mystery by a non Christian and as soon as an evangelical Christian is introduced, the mystery is over for me.

I like the Manny Rivera series and will continue to read but another hypocrite evangelical Christian 😱, so original.

But even the curmudgeon hypocrite Christian in me, will give it 4 stars for the clean and caring Manny Rivera.

6/23. 4.5 stars. Manny is called to investigate the apparent murder of a young man who was writing a history of a ranch once used as a hideaway for outlaws. Lingering in the backfround is the unexplained disappearance of a young girl 30 years prior. Could the historian have discovered something about the young girl?
Could Manny's wife Gloria help him out? Great book, excellent series. I'm so sorry to see the series end - I loved reading about areas that I have loved visiting.

As always, a pleasurable book by a very good author

It's been awhile since I've read the previous Manny Rivera novels and had forgotten how much I enjoy the author's stories. Not only do you meet well, fully developed characters, but you get swept into the high desert country. And just to read about it as Curtin describes it is amazing. His love of the area comes through in a way that takes you to the land he obviously respects.

One of his best!!

An extremely interesting mystery. Manny had to find a lot of puzzle pieces this time.

I have left reviews on his books, but I do not think I mentioned that he makes you want to visit Utah. My husband and I broke down on an highway in Utah. It took several hours for a tow truck. I regretted not being able to see a beautiful part of Utah because it was dark by the time the tow truck got there.

Excellent!

Unusual current murder and 30 year old skeleton give Many something to investigate! Manny does his usual thorough investigation and meets many new, interesting people who don't appear to be suspects. Digging deeper into the past reveals a possible connection between the new murder and the skeleton with no obvious past. Great plot and unusual conclusion.

Great series

This is a gentle crime series if such a genre exists. The pace is steady and pulls you along at an enjoyable and thrilling pace. Somewhere between the Longmire Wyoming sheriff novels and the Spenser Boston detective books are the stories of Moab, UT Deputy Sheriff Manny Rivera. Love this series!

Great Reading

I love reading about the city and even following the locations he is writing about in the book on a map. The personalities of the characters keep me following the individuals as well as their part of the story. Keep writing, Rich. I hate waiting for the next book to be released.

An intriguing story and series

This was an interesting and intriguing story that intertwines the past with the present, in more ways than one. It was heartbreaking, full of drama, tragedies, as well as plenty of life lessons. I would really like to see more stories in this series.
I would definitely recommend this book, series, and outstanding author.

My Favorite Rivera Tale Yet

I’m not wordy and can’t go on for too long, but if you like interesting western-themed mysteries, go ahead and read all of Mr. Curtin’s novels. You will not regret it.
This is my favorite novel he has written, which I have read up til now, and look forward to the ones ahead.

Ranch with Outlaw History

A young man is murdered for digging up history. Deputy Manny Rivera interviews all of the people associated but comes up empty handed. His new bride notices a discrepancy. The story is well written and I did not guess the killer. I’ll look for more of Rick Curtin’s mysteries.

I really enjoyed this book, the story was well written and I found myself visualising where it took place.The introduction of the far past, the cowboy era and the near past, 30 years ago, made for a very interesting read. Also tying up everything with a final climactic end was cleverly executed.I shall certainly look out for further books by Rich Curtin.
