Murder in Siena: When Crime Meets Chianti in the Armstrong & Oscar Series
Last Updated on April 22, 2026
Have you ever felt like there are so many books and so little time to read them all? That happens to me especially when I’m in the middle of a series and I just want to keep going and read them all one after the other.
Case in point is the 4th book in the in the Armstrong and Oscar cozy mysteries series by T.A. Williams – Murder in Siena. I’ve read and reviewed the previous three: Murder in Tuscany, Murder in Chianti and Murder in Florence but with my TBR list getting longer by the day, I generally have to leave a bit of time between each new installment.
Anyway, if you’re anything like me, you know there’s a special kind of joy in picking up a cozy mystery, especially when it promises a sun-soaked Italian setting, a clever whodunit, and a four-legged sidekick who’s as much a star as the human sleuth.
Murder in Siena delivers all this and more, whisking us away to the rolling hills of Tuscany for a weekend that’s anything but relaxing.
A Tuscan Getaway Gone Awry

Dan Armstrong, our affable British ex-cop turned private investigator, is ready for a break. He and Anna, his new love (and a historian with a knack for making even ancient murals sound fascinating), head to a countryside hotel near Siena.
Their plan? A lazy weekend filled with sightseeing, good food, and maybe a glass or three of Chianti. Tagging along are Dan’s loyal black labrador Oscar, who, let’s be honest, is everyone’s favorite character, and their friends, Detective Inspector Virgilio and his wife Lina.
But as any cozy mystery fan knows, a relaxing holiday is never just that. Cue the howling in the night, rumors of wolves prowling the countryside, and the discovery of a mutilated body on the hotel grounds.
Suddenly, Dan is back in detective mode, Oscar is sniffing out clues (and probably the odd sausage), and Anna’s historical expertise is coming in handy in ways she never expected.
A Locked-Room Mystery with a Twist
What makes Murder in Siena such a treat is its classic setup: a self-contained hotel, a cast of quirky suspects (most of them environmental conference attendees), and a murder that initially looks like the work of wild animals.
But as the local police quickly discover, the wounds are a little too precise, the circumstances a bit too suspicious. Is there a killer among the guests, or did a wolf really go rogue?
Dan, with Virgilio’s help, starts the painstaking process of interviewing suspects. The author excels at giving each character, no matter how minor, a distinct personality, making the suspect pool both lively and believable.
There are academics with secrets, delegates with hidden agendas, and more than a few red herrings to keep you guessing. Honestly, it’s like Clue, but with better food and more scenic views.
Red Herrings, Real Wolves, and Relatable Characters
Williams is a master at weaving in red herrings. Just when you think you’ve got it figured out, another clue sends you in a new direction.
The investigation unfolds at a steady pace, with Dan’s methodical approach balanced by Oscar’s comic relief and Anna’s insightful observations.
The interplay between the characters is a highlight; Dan and Virgilio’s friendship is particularly enjoyable, full of mutual respect and the kind of banter that makes you wish you could pull up a chair at their dinner table.
Speaking of dinner, food lovers will find plenty to savor. Williams doesn’t skimp on the culinary details, and the Italian meals are described so vividly you’ll want to book a flight to Tuscany – or at least order takeout.
The setting is equally immersive, with the Tuscan countryside, Siena’s medieval streets, and even a side trip to a farmhouse with a mysterious mural all painted in loving detail.
Friendship, Romance, and Second Chances
Beyond the mystery, Murder in Siena explores deeper themes of friendship, romance, and the challenges of balancing work and personal life.
Dan’s relationship with Anna is still new, and their dynamic adds a sweet layer to the story. She’s supportive, clever, and brings her own expertise to the table.
Meanwhile, Virgilio and Lina’s marriage faces its own trials, echoing some of Dan’s past struggles. These subplots give the book emotional depth without ever feeling heavy-handed, and they make the characters feel like old friends you’re always happy to visit.
A Whodunit That Lets You Play Along

One of the greatest pleasures of this series, and this book in particular, is the way it invites you to solve the mystery alongside Dan. Clues are presented clearly, suspects are whittled down one by one, and you’re encouraged to guess, theorize, and second-guess yourself at every turn.
And if you’re anything like me, you’ll probably be barking up the wrong tree (pun absolutely intended) more than once. The solution is satisfying, with enough twists to keep things interesting, but not so outlandish that you feel cheated.
Williams’ writing is warm, witty, and peppered with just the right amount of humor. There’s a particularly memorable scene involving two academics debating the finer points of canine droppings – a moment that perfectly captures the book’s blend of lightheartedness and genuine intrigue.
Even as the stakes rise and the body count threatens to climb, the tone remains friendly and inviting, making this a perfect read for a lazy afternoon (preferably with a cup of coffee and a biscuit or two).
A Few Quibbles
No book is perfect, and I found that the pacing can lag a bit in the middle and I did wish for a bit more suspense in the climax.
I also couldn’t work out the point of the sub-plot involving a couple who are living off the grid but maybe that connects to a later book in the series.
But these are minor quibbles in an otherwise delightful package, and most fans, myself included, are more than happy to forgive a few slow chapters when the journey is this enjoyable.
A Cozy Escape Worth Taking
Murder in Siena is everything a cozy mystery should be: engaging, atmospheric, and just challenging enough to keep you guessing.
The Italian setting is a feast for the senses, the characters are charmingly real, and the mystery is well-constructed, with enough twists to satisfy even the most seasoned armchair detective.
Whether you’re a longtime fan of Dan and Oscar or a newcomer to the series, this book is a perfect escape-one that will leave you smiling, hungry for pasta, and eagerly awaiting the next adventure.
