Murder at the Duomo

Armstrong and Oscar, Book 14

By: T A Williams

Don't miss the BRAND NEW instalment in the brilliant, BESTSELLING Armstrong and Oscar Cozy Mystery series by T.A. Williams. A gripping murder mystery set in beautiful Florence featuring a retired DCI and his loyal companion, Oscar.

Even angels can have a dark side...

As the sticky heat of August settles over Florence, Dan Armstrong is ready for a well-earned break—sightseeing with fiancée Anna, daughter Tricia and her fiancé Shaun. But when a British man is found dead inside the city's magnificent Duomo, Dan's plans quickly change.

The victim, Tristan Angel, is 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 confession?

At Angel's opulent villa in the hills of Fiesole, Dan and Commissario Virgilio encounter a colourful cast of suspects—each one hiding secrets and none too eager to talk. As tempers rise and the heat outside grows ever more intense, Dan and his four-legged sidekick, Oscar, must sniff out the truth before the killer strikes again.

Another impeccable mystery!!

I hope these books never stop. I so enjoy the story as the characters and the narrator is beyond excellent! This is another good mystery which honestly kept me guessing until the end! I think these are so clever and fun and I’m totally invested!

Another great story!

I love these cozy mysteries. The writing is good and the voice actor is wonderful. This is another great story in the series.

Very enjoyable!

I really enjoy all Amstrong and Oscar Cozy Mysteries. Very entertaining. The series transports you to Italy

Another Great Adventure for Dan and Oscar

I very much enjoyed the plot which kept me guessing until the end. It was fun to visit with the main characters who now seem like old friends to me (I have read/listened to all the books in this series). The story settings of Florence and Fiesole were a joy to experience, and as a former resident of Florence, I can say they were authentically portrayed. The story brought me back to a delightful time and place (although thankfully, murder-free ;)) I look forward to the next mystery investigated by Private Detective, Dan Armstrong and his best pal Oscar (a sometimes officer/sniffer-dog of the Florence Murder Squad).

Fabulous!

Great plot. Interesting characters. Beautiful descriptions. Meaningful content. Old friends. My favorite book in the series!
