It’s part of the Armstrong and Oscar Cosy Mysteries book 14 I didn’t enjoy it of if I am hones, I found it boring good story line

Review of advance copy received from Publisher
I thoroughly enjoyed my virtual visit with Dan and Oscar. In fact, there are spots in the book that had me wishing I could just book a flight to Florence. While that's not likely to happen, I found Williams' descriptive passages a great virtual trip as the plot and side stories moved along. Williams had me easily visualizing the setting as he takes us along the ways and byways of Dan's adopted home. While the murder investigation was obviously the focus, I liked the home scenes, too, where we got to to know not just Dan better but his family and associates. Dan is someone who enjoys his occasional involvement in police work outside his usual private detective agency but seems to have a firm grasp on what is really important in his life, his friends and loved ones. Loved his sorta "whatever" attitude toward wedding plans. As for Oscar, he definitely has figured out who the weak links are to snag a doggie treat from, that's for sure, even among the suspects as it turns out.
And, whoa, there are lots of suspects. The victim, Tristan Angel was definitely no angel. Instead, he was deeply involved in illegal arms dealing and surely had countless enemies who'd want him dead. That aspect pulls in intelligence agencies from here and there, much to the displeasure of Commissario Virgillo Pisano of the Florence police murder squad. He's probably Dan's best friend in Tuscany and finds Dan particularly valuable when the English language is needed. Probably doesn't hurt that Dan is ex-Scotland Yard, either. In any case, Angel's closest team members are all suspects. Most likely, you'll find yourself even liking some of them, hoping they aren't the killer.
Bottom line, a fun, interesting, multi-layer mystery with equally interesting characters, both family and suspects. And, of course, Oscar was my favorite. That dog knows how to make friends everywhere. The setting makes me wish I could see it for myself and it was fun to drop out of the mystery vibe at times and see what Dan was seeing. Not being a hot weather fan, either, I bet Dan wanted to jump into a couple of those fountains with Oscar, too. I came into this series late and this is only my second read of the series but I'm hooked and looking forward to the next installment after checking the library for early adventures. Thanks to #BoldwoodBooks for introducing me to Dan and Oscar and giving me this early peek into their lives in beautiful Florence.

Dan and Oscar sniff out murder
The latest Armstrong and Oscar cozy mystery takes place at the famous Duomo in Florence, Italy. Retired DCI Dan Armstrong and his fiancée Anna are entertaining Dan's daughter Tricia and her fiancé at their home in Tuscany. Dan's friend, Commissario Virgilio Pisano of Florence's Murder Squad, calls him for help. A man’s body turns up in a confession booth at the Duomo. How did someone manage to kill him among all the tourists in the cathedral at the time? And who is the man?
Although Dan is there to provide English translation, Virgilio respects Dan's detective abilities. Dan is a former DCI with Scotland Yard. Dan has a way of coming up with new angles, and his dog Oscar often sniffs out new clues. The mystery becomes even more interesting when the victim is Tristan Angel, a wealthy arms dealer. Angel is the CEO of TXS, and some of his top employees are staying at a nearby villa. When another body turns up, it appears to be the equivalent of a locked-room mystery. Oscar's good nose and Dan's deductive skills are put to the test to solve this crime before the police are forced to turn the suspects loose.
I love T A Williams' wonderful descriptions of Florence and Tuscany. You almost feel the heat bearing down and see the beauty of the area. He is also wonderful at describing the fantastic meals that the characters enjoy. But the best is the thoughtfully crafted mystery that unfolds. I also love that Oscar isn't just a mention. The black lab is an integral part of the plot. I am with Dan, a person is highly suspicious if Oscar doesn't like them. The more I read this series, the more I appreciate Viriglio and the other members of the murder squad. This is the 14th book in the series, and it keeps getting better. Every time I read one, I get to experience Italy again.
If you are in the mood for a great mystery with a large helping of beautiful scenery and culinary delights, you can't do better than Murder at the Duomo. Readers who enjoy Martin Walker's Bruno, Chief of Police or Donna Leon's Commissario Brunetti series should consider trying the Armstrong and Oscar series.

Dan Armstrong is surrounded by family, and Oscar of course, as they enjoy their evening meal, cooked by Dan as he shows off his recently learned culinary skills. His daughter Trisha is there with her fiancé Shaun as they are planning their soon to be wedding. Trisha would like to have it in the hills of beautiful Tuscany and Anna is helping her with venues.
Dan and Oscar find their peace shattered in Murder in the Duomo, when a call comes from Virgilio, or rather Comisario Virgilio Pisano of the Florence murder squad, to help with what seems to have been a murder at the Duomo, or the Cathedral of Santa Maria del Fiore. The victim is a high-profile British businessman considered as the richest man in the world.
The pressure is on to get a quick arrest before it becomes an international issue, as the murdered man, Mr Tristan Angel is also a major arms dealer, with powerful friends and allies as well as enemies.
As they dig or try to dig deeper into the affairs of Tristan Angel they are blocked at every turn as the people who accompanied Angel to Fiesole, are telling a version of the truth which seems to be plausible but leaves much to be explained.
Who had reason to kill, to carefully plan what now seems to be an execution is unclear, as it seems the murderer is not about to stop at one and anyone of the people still at the Villa may have had reason to kill; they all appear to have cast iron alibies.
In this fast moving, Tuscany style Murder, Dan and Oscar find they are, as are the Police, left confused and intrigued as every lead ends in a dead end. It is only a quirk of fate that may shine a very small light on a person who appears to be blameless. Are they the killer or are they hiding someone else in plain sight?
Murder at the Duomo is once again an excellent cosy murder from TA Williams, featuring a tightly woven, complex plot which leads the armchair detective to false conclusions time and time again. A great and most enjoyable murder once again!!

Thank you to NetGalley, Boldwood Books, and T.A. Williams for an advanced reader copy of “Murder at the Duomo” in exchange for an honest review.
I really enjoyed this book! This is book 14 in the Armstrong and Oscar Cozy Mysteries series. Although this was the first book I’ve read of the series, I didn’t feel like I was missing out by not having read the first 14 books— I can see how they would all tie-in together (a few references are made to past mysteries in this book), but I would ultimately consider it a cozy stand-alone.
I requested this book on NetGalley because I went to Florence last year (and the whodunit premise was fun), and I was excited to read a book set in Florence— and it did not disappoint AT ALL. T.A. Williams writes really enchanting and beautiful settings, and I think that was actually my favorite part of this book. He literally managed to take me right back to Florence, and I’m so grateful for that!
I also thoroughly enjoyed the mystery aspect of this book. It was never too scary or spooky, and I was able to follow along easily with the characters and the plot. In the beginning, it was a little difficult to keep track of everyone, simply because there were SO many suspects, but the author does a good job of continuing to remind us of who’s who so we’re not floundering through the book.
The subject matter was interesting (a murdered questionably moral arms dealer), and I thoroughly enjoyed the way the author handled the difficult and sketchy details of a scenario like this.
There were moments and details that needed to be handled delicately and with respect, and the author did just that, and I was really impressed with the finesse and care used.
I enjoyed “Murder at the Duomo” a lot, and I will definitely recommend it to anyone that enjoys a clever whodunit and/or also wants a little escape to Florence, Italy! ♥️

Originally reviewed for Chick Lit Central (www.chicklitcentral.com)
Is this really the fourteenth book in the Armstrong and Oscar Cozy Mystery series? All of the books are great, with Murder at the Duomo yet another great addition. This time, the original plan for Dan is to spend some much-desired time with his daughter and daughter’s fiance, yet crime never stops for anything!
I like that the reader gets to learn a little bit more about Dan’s family. We’ve heard about Tricia, but it was nice to see more of her in this book, and learn that she’s engaged to be married. Dan is also engaged to Anna, which feels like it’s been a long time coming but well worth the wait. As per usual, Dan is called in to assist on a murder investigation, which is always an intricate, well-researched affair, but this time we’re given more roots to what makes Dan tick by learning more about his family.
The synopsis mentions a colorful cast of suspects, and that is absolutely correct. Given the nature of the situation, no one can leave the villa or enter the villa, which really adds to the pressure of the environment for all of the characters involved. While reading Dan’s checklist, I follow along and create a list of my own, attempting to figure out who might be the culprit, no matter how far fetched it might be, and I found it fun that Dan also had some unbelievable ideas, especially when it involves those he knows who are closer to his neck of the woods. You never really know when an Armstrong and Oscar book is involved.
One by one, suspects are removed, leaving behind the final answer, and as usual, it was the last person I suspected. Dan approaches his theories in a very methodical manner, and it works really well. Murder at the Duomo was a fun five-star addition to this series, and I look forward to many, many more!

Murder at the Duomo is an exciting murder mystery set in the beautiful background of Tuscany's sunsets. There are too many suspects and even more motives.
Dan Armstrong and Oscar are back with a very complex murder. As Dan, his fiancé Anna, his daughter Tricia with her fiancé Shaun search for locations for their weddings, a murder puts their search on hold. A world renowned arms dealer and one of the richest men in the world is shot inside the Duomo (The Cathedral of Santa Maria del Fiore). Commissario Virgilio Pisano will need Dan and Oscar's help solve this murder. But things start getting harder to decipher when Donald Hicks, Tristan's right hand is poisoned inside Villa Botticelli where all of Tristan's employees are staying. After a failed attempt at shooting Vincent Archer, one of Tristan's directors, it becomes apparent that someone is trying to take out the main employees of the company.
It is always so nice to see beloved characters return in a series that you love. I enjoyed reading more about Dan as a future husband and father. I felt like Oscar was extra funny this time around following beautiful women and always looking like he is being starved. Though Dan is helping solve murders, he also gets to enjoy the beautiful things that Italy has to offer. His walks are always so soothing. Another great read from one of my favorite authors!

3.5 stars. A fun cozy mystery set in beautiful Florence.
Dan Armstrong has been enjoying a relaxing summer with his fiancée Anna, daughter Tricia, and her fiancé Shaun. Then a British man is found dead inside the Florence Duomo. Tristan Angel was a wealthy arms dealer and an interesting group of people joining him at a villa in the area. Dan and Commissario Virgilio need to figure out everyone's secrets before the killer strikes again.
This is a fun cozy mystery series and I really enjoy the Florence setting. It's described to capture the beauty (if somewhat ignoring the tourist crowds) and lets us get a taste of the city and the surrounding countryside. The mystery itself has many possible suspects, which keeps it interesting. An, of course, Oscar the dog is adorable.
I think the pacing was not my favorite, and perhaps there were too many people as potential suspects as they were difficult to tell apart at times. The writing is clear, but maybe not my favorite voice to read from.
Overall, if you enjoy cozy mysteries, definitely give this one a try. It's a fun story, perfect to enjoy with a prosecco or an aperol spritz to feel like you're there in Florence.

I like this cozy mystery series mostly because of the settings. Williams does a great job of taking us on location, seeing and experiencing the buildings and landscapes. Here we get to experience the Cathedral, or Duomo, in Florence, both the beautiful exterior and the more plain interior. Dan and Oscar roam around various areas so we experience scenes overlooking the city too.
The mystery is good, taking us into the world of arms sales, exploring the ethical nature of selling arms to various entities. The possible suspects are many and it takes in depth investigation by the local Commissario with the help of Dan and his contacts from his previous government work. But the hero is Oscar who manages to find an essential clue.
This is a good cozy mystery for readers who like ones set in unique places and have interesting characters. There is a good balance of investigation and Dan's personal life. Williams' writing style is clear and entertaining. While it is down the line in the series, it reads well on its own.
I received a complimentary egalley of this book from the publisher. My comments are an independent and honest review.

This is a great series! Armstrong is a former member of the Scotland Yard murder crew, and is now in Tuscany. He has his own detective agency, and helps out his good friend Virgilio, who is Chief of Police in Florence, especially when the people involved are English speakers. Oscar is Armstrong's Labrador, is with Armstrong almost all the time, and helps with most of the cases. This case is about a company that sells weapons to folks who shouldn't have weapons. The company owns a villa in Florence and several of the top employees are there for a meeting. However, on the first day, the Chair of the Board is murdered in a confession booth in the Duomo. There seem to be a lot of guns in the house and some tension among the folks in the company. Soon, there is another murder which is of the 2nd in command of the company. However, they finally figure out who has been murdering the bosses. Oscar has an important role in finally catching the murderer.
I thank Netgalley and Boldwood Books for the ARC so that I could read the book before publication.

Armstrong and Oscar #14
As the sticky heat of August settles over Florence, Dan Armstrong is ready for a well-earned break - sightseeing with his fiancee Anna, daughter Tricia and her fiance Shaun. But when a British man is found dead inside the city's magnificent Duomo, Dan's plans quickly change. The victim, Tristan Angel, a super-wealthy arms dealer with a saintly name and a devilish reputation. But what was he doing in the cathedral, and who decided to make it his final confessional at the Duomo?
This is a descriptively written story. Dan Armstrong is a former member of Scotland Yard's murder crew. He now has his own detective agency. Dan and the Italian police are investigating who killed Tristan Angel in the confessional at the Dummo.
I quite liked this cosy murder mystery. It does read well as a standalone.

Dan, a retired DCI who now runs a detective agency in Florence, is called in again by the local police when a British arms dealer is found dead in a confessional box in the Duomo, the cathedral. He had been staying in the firm's exclusive villa, where other senior members from the company are also staying.
Although this is the 14th book in this series I've only read one previously, which I did enjoy, and it is readily read as a standalone. It is a slow paced book, so maybe not for those who enjoy faster paced books, but I do prefer books like this. Again the location is stunning, I've only visited briefly but I'd love to go back again. There is a varied collection of suspects staying at the villa and it is really difficult to work out who is the guilty person. He is aided as ever by his faithful companion Oscar, an ever-hungry Lab, who has many uses from finding clues to reassuring witnesses. Something to read to warm you up on a cold winter's evening.
I received an advance copy of this book from the publisher through Netgalley, however this did not influence my review of the book.
Although this is the 14th book in this series I've only read one previously, which I did enjoy, and it is readily read as a standalone.

Review of advance copy received from Netgalley
Murder at the Duomo is somehow the 14th book in the Armstrong and Oscar mysteries, and I've read them all (apart from 1, which I seem to have missed).
This time, Dan and his friends in the Italian police force are faced with their most impossible case so far. Who killed Angel in the confessional at the Duomo, and how did they do it?
Often, these cases are very hard to solve until something becomes obvious to Dan or Oscar, and then they become quite clear-cut, but that's not the case this time. It does make some aspects feel a little repetitive with such a small collection of suspects. It does mean that when the solution finally becomes evident, the ending is quite exciting.
I do love these mysteries, even if they entirely put me off ever going to Tuscany, which is evidently too hot and too busy for my liking. I think I'll let Dan and Oscar continue to enjoy it (or endure it) on my behalf.

My favorite duo 🐶 is trying to discover who killed an English arms mogul Tristan Angel, who everyone wants dead, even his ex-wife that is in Florence at the time of the murder, conveniently…
Dan could not catch a break, he was supposed to wander through the beautiful city with his fiancée, Anna and with Tricia and Shaun: her daughter and her fiancée and of course, Oscar!
As a former London Police, now a PI is asked to help the local police. Angel died in a confessional at the Duomo di Firenze who was believed to have met someone. At the deceased’s villa, where his entourage live while they accompany him everywhere he goes, everyone is a suspect but with the help of Oscar, every task is easier!
The Italian riviera is a perfect setting for this book, I always enjoy this couple of PIs

The fourteenth in the Armstrong and Oscar cosy crime series following ex DCI Dan Armstrong and his black lab Oscar as they solves crimes around Italy. Dan is relaxing in Florence with his partner Anna, and his daughter and her fiancé, when he is asked to help on a case involving the murder of an arms dealer in the Duomo (cathedral).
Briefly, visiting the victims villa in Fiesole, with Commissario Virgilio, Dan finds a plethora of suspects so there is plenty for the pair to investigate. When a further murder occurs and still no clear suspects emerge it is clear they, along with the local police, need to up their game.
Using the delightful background of Florence and its neighbouring surrounds we are treated to a discourse on Italian food as well as the antics of Oscar as he helps Dan. I do love it when Oscar gets a starring role. With a surprise from his partner Anna at the end this was a really enjoyable read.

Another cozy trip with Dan and Oscar!
If you’ve read this series before: you get all the best aspects of this series - Dan and Oscar, their friends, the charming town, and writing that will make you want to book a flight to Italy asap. However, it wasn’t my favorite mystery of the series. It felt a bit too broad, with the ending being both lack luster and failing to tie up all the loose ends.
If you haven’t read this series before: it is a standalone part of a broader, interconnected series. So technically you can read this, I just personally would recommend reading one of the older ones since k think their mysteries tend to be a bit more tight and tidy.

It's August in Florence and it's hot. Dan and Oscar are looking forward to spending time with his fiancee Anna, and his daughter and her fiance.
Things change when a body is found in one of the confessionals in the Duomo. Virgilio, the local Police Commissario, asks Dan for his help in identifying the body.
They discover that it is Tristram Angel, the CEO of arms company TXA. He was staying at his villa with various people from his company and they are all suspects.
Slowly Virgilio and Dan, with the help of Oscar start to work on why he would have been killed. There are red herrings along the way and another murder. Will they catch the killer before they have to let the occupants of the villa go?
A nice cozy crime with beautiful descriptions of the Tuscan countryside.

Dan gets involved in an investigation when a British arms dealer is murdered in the confessional at the Duomo.
Tristan Angel was one of the founders of TXA Supplies, one of the world's largest sellers of arms and his death has created a power vacuum - was he murdered by rivals? Was it a government sponsored hit? Was it related to his infamous womanising? Tristan was on holiday in Florence with several colleagues - was it a power grab by one of his partners?
Yet another charming cosy mystery set against the stunning backdrop of Florence and amazing food, with Oscar the dog as Dan's faithful sidekick. The suspects are plentiful and it is going to take some good detective work to find the motive but Dan and Virgilio will do it.
I received an ARC from the publisher via NetGalley.

Another in the series of Armstrong and Oscar cosy mysteries. Dan has his daughter visiting and gets called in to help Virgilio with the death of an Englishman in Florences Duomo. Dans daughter Trisha is in the process.of arranging her upcoming wedding and looking for venues. Meanwhile Dan and Virgilio are struggling with finding any evidence in the case. This is a lovely cosy mystery with lots of interaction with Oscar who helps the story along. This is a nice relaxed read from characters we have got to know over the last fourteen or so books. Absolutely recommend this book for the escapism and an easy read.
With thanks to the author, Boldwood Books and Netgalley for the opportunity to read this book.

Detective Dan Armstrong and Oscar at the duty again.
But this time Dan has his wedding plans with his fiancee Anna, and also his daughter Tricia is visiting him and planning her own wedding.
And like usual, inspector Virgilio needs Dan help with the murder of Tristan Angel , that took place in the duomo.
In the time they search for evidence and interogates the suspects, another crime took place and one of the suspects was shoot at.
This time my suspicious was correct but that didn't took from the pleasure to read the story.
I liked this story too, detective Dan and his labrador , Oscar have solved another case again and helped their friend Virgilio.
Thank you Boldwood Books and Netgalley for the opportunity to read the book in advance. This is my honest and only opinion.

This is such a great series and each story is engaging from page one. One thing I really like is how the chapters are set out along with how the story flows and develops. Dan and his trusty sidekick Oscar the Labrador join the local police in Florence when a British man is found dead at the Duomo. They are initially involved to help with translation issues but as always Dan becomes heavily involved and his help is gratefully received! The murdered man turns out to be arms dealer Tristan Angel and there appear to be plenty of suspects. I really like how Dan’s own life is threaded through the stories and how the interactions between the characters is written. With the gorgeous backdrop of Florence and well developed characters this is a great addition to a very enjoyable series that I highly recommend

Although this is part of a series, it's quite easy to work out who's who and their backstories.
Dan's daughter and her fiance come to visit and discuss wedding plans (Dan's, as well as her own). But then Tristan Angel, an arms dealer, is shot in the Duomo and Commissario Virgilio needs Dan (and Oscar the labrador) to help solve the case. They think it's likely to be an unhappy customer, until a second member of Tristan's group is found dead at the luxurious villa just outside Florence - and is there dissent among the ranks?
Lots of red herrings, some great characters, fabulous setting and a twisty plot. Thoroughly good read.

Dan Armstrong is a retired Scotland Yard detective turned Private Investigator, now living and working in Italy. Along with his pet Labrador Oscar he has often helped the local police when the crime involves English speaking individuals. This time he is asked to assist when a wealthy British business man is found dead in a confessional in Florence’s cathedral. There are few clues for the team to follow and when it is found his business is in the arms trade they fear the killer could be from anywhere, but then there is a second death.
Another good read in this series and my thanks to NetGalley and the publishers for the arc.

An arms broker is murdered in a villa, and the list of suspects is endless since it includes anyone he sold weapons to as well as their enemies. A second murder helps narrow the field, and Dan Armstrong helps the Florence homicide investigative unit solve the cases. The descriptions of Florence - its history and culture - are on point as always. The plot had some gaps, and the reveal scene wasn't entirely plausible, but the overall charm of the series remains. Thanks to NetGalley and Boldwood Books for the eARC.

Thank you to Netgalley for the opportunity to read this book. 3.5 stars. I so love being back in the company of Dan and Oscar. These books can be read as standalones but do follow the life of retired police detective Dan Armstrong, now a private investigator and his faithful dog Oscar – now both living in Italy. This time a wealthy arms dealer, Tristan Angel, is found dead inside the famous Duomo (cathedral) in Florence. Tristan had a villa in the hills and his business colleagues were all staying there at the time. Could one of them be responsible? Another great cozy mystery.

Good addition to the series😊
Love this investigative duo and the Italian setting. Once again, sidekick black lab Oscar comes up trumps and contributes big-time to Dan's assistance in a multiple murder case which started with the murder of a wealthy British arms dealer in Florence's famed cathedral. After that, it sort of resembles a Christie closed venue mystery, with a group of characters installed in a beautiful villa in the Fiesole hills and all potential killer (or victim!).
This plot also makes big advances in Dan's personal life. I like the way the author balances the plot between Dan's personal life (often in danger of being overwhelmed by his eager participation in a murder case!) and his work with the Italian police. Good suspense, easy to read and on point descriptions of the lovely setting.

I love these mysteries from TA Williams, and Dan and Oscar are both on fine form again in Murder at the Duomo.
Beautiful descriptions of the Tuscan countryside are again woven into the murder mystery and I loved how we got to see more of Dan’s daughter Tricia and her fiancé Shaun.
This case is an interesting one for Dan and Virgilio, and with the possible introduction of the secret services into the case due to the victims history, it adds an extra complication that neither of the men was impressed with. Luckily Oscar is on hand to provide the distraction and sleuthing needed to aid with the puzzlement surrounding the mystery

Brilliant cosy mystery book with the perfect scenery, settings and characters. I love the series. It’s great to catch up with Dan and Oscar and their pursuits. This time it was the murder of an arms dealer that Dan finds in the confessional box at the Duomo. From that moment he is in the case. It’s fast paced, exciting and definitely cosy.
This is a great series but also reads brilliantly as a stand alone too. Thank you NetGalley for this arc in exchange for an honest review.

Well written and easy to read with a well paced and methodical unravelling of clues. I enjoy reading novels set in places where I have been, there is a sense of comfort and familiarity and Florence in particular is a place I liked. I received a complimentary copy of this book. Opinions expressed in this review are completely my own.

effective mystery with some good plotting and a fantastic conclusion with a very sympathetic antagonist. 5 stars. tysm for the arc.
