MIllstone of Doubt is the continuation of the Thorndike and Swann series. I definitely recommend you read the first book, The Debutante's Code before starting the second in the series. This book continues where the first one left off as Daniel and Juliette navigate their new roles as agents for the Crown. Beloved characters from the Serendipity and Secrets series continue to play a role in this series. I loved that since I am never really ready to say goodbye to my favorite characters. The story is full of mystery, murder, deception and intrigue with some romance and a beautiful faith-based message sprinkled in. It had some predictable moments and scenarios that were similar to other novels I have read recently, but I loved it anyway. I can hardly wait for the next book in this series to be published.
If you like a clean mystery novel then I highly recommend Millstone of Doubt

Thank you Kregel and Net Galley for the free DRC of this book. The opinions expressed here are my own.

I loved seeing Daniel and Juliette’s relationship progress. The relationship has been rather slow-burn, but Millstone of Doubt left me satisfied, though I’m still hankering for more.

The murder mystery was interesting, and though I figured out the culprit, Vetsch had me second-guessing myself. But it was the other mystery solved in this book that had me reeling. I don’t want to give anything away, so I’ll leave it there. Just know that Vetsch throws a curveball like no other.

There’s also this really great faith arc for Daniel. I liked the discussion he has with Ed about God as our Father and the way He takes care of His children.

Millstone of Doubt can be read as a standalone, but you’ll enjoy it more if you read the first novel, The Debutante’s Code.

Overall, Millstone of Doubt is a compelling Regency mystery with plenty of romance. Michelle Griep fans (or any Regency fan in general) will love this novel.

Erica Vetsch knows how to write a gripping mystery. From the first page I was intrigued by the returning cast of characters and new additions as an intricate web of suspicions and danger was spun. After an ominous explosion rocks a mill in the city of London, Lady Juliette and Daniel must combine their skill sets to find the killer of Juliette's friend's father.

Historical mysteries will always be my genre of choice, and Millstone of Doubt does not disappoint. I would recommend that you read this book after The Debutante's Code to fully follow the trajectory of the characters' stories.
