This book is part of a continuing story about our lead characters and their family. In this one, an old nemesis has returned and threatened them . It's time to stop her once and for all. It will not be easy.
There is a lot of danger, excitement, and adventure. The plot is fast-paced and keeps you interested all the way through.
I have read and thoroughly enjoyed all of the books in the series. I hope they all get the happy ever after they deserve.
Great fun.

Thanks to Netgalley and Dragonblade Publishing for this ARC. This is a great series that has gone from strength to strength. I love the characters and their depth. The plots are always great and twisty. Looking forward to the next installment

Kara and Niall are now the Duke and Duchess of Sedwick, but they prefer to remain the people they were before dukedom. Unfortunately, a past enemy as resurfaced. She is determined to destroy Kara and Niall and all they love. However, her plans also include colluding with Russians and destroying high ranking members of government. How can they stop someone who is willing to get rid of everyone who gets in her way? Petra Scot is one of most dastardly villains that I have come across in many years. She seems capable of allowing nothing to stop from getting what she wants, not even her own family. Dealing with her, handling her is a close thing for Kara, Niall and friends, and not without pain and loss. It all makes for great reading, fast paced, hard to put down. With each book in the series, the author develops her characters, including the secondary ones, a bit more. How can the reader not be all in and look forward to the next installment.

Another great historical mystery from Deb Marlowe chronicling the adventures or Kara and Niall, the Duke and Duchess of Sussex.. The plot is suspenseful and so action packed it keeps the reader engaged until the end. Though I haven’t read the previous books in the series, I was able to jump right into the current book and it was never a dull moment. Now I have the pleasure of reading the first 5 books before the next in the series releases.
I received an ARC from NetGalley and I am voluntarily leaving a review.

Happily wedded bliss...

Niall and Kara are married, they are at Bluefield, and in Scotland and are officially the Duke and Duchess.
Its two years since they first met at the Great Exhibition. This was a slow burn. But are they quite content to stay uninvolved? There's a trickster about doing bad things.

What was the highlight of this book was how supportive Niall was of Kara and the emotional growth he's done to be in a good place with Kara, so they can do the sleuthing.
Recommend.

A beloved mystery series continues, in this fast paced story. Kara and Niall are back and planning on settling down now that health has been restored. Yet, the past seems to want to continually plague them. A great story that can be read alone but if you want to get the full picture, immerse yourself in the joy of these two while they banter and solve case after case, then I recommend reading the series in order. You will never be bored.

Thank you so much to NetGalley and Deb Marlowe for providing me with a complimentary digital ARC for Betrayal from Beyond coming out April 14, 2025. The honest opinions expressed in this review are my own.

This is the first book I’ve read by this author. I have the other books in the series, but haven’t read them yet. I really love cozy historical mysteries. I think this book was fun. I enjoyed the characters and the plot. I definitely would check out other books by this author.

I would recommend this book to anyone who enjoys historical murder mysteries!

This sixth book in The Kier and Levett Mystery series is another well written entry to this series. This book concentrates on action more than relationships and is full of action, drama, intrigue, suspense and conflict as an old adversary appears bent on revenge so not a mystery in the traditional sense but more about protecting their family and friends with many twists, and turns kept me very engaged. I received an advance review copy for free, and I am leaving this review voluntarily.

This series just keeps getting better and better!

I love the character development of Kara and Niall, plus all of their friends they have collected throughout their journey. Their fight against their enemy Petra showed just how important it is to have strong relationships, as Kara and Niall have the backs of their loved ones and vice versa.

The first chapter had me hooked, and it kept me guessing until the twist was revealed.

I can’t wait to read the next!

4.5 stars out of 5 ⭐️

Betrayal from Beyond by Deb Marlowe
The Kier and Levitt Mystery series #6. Historical mystery. Can be read as a stand-alone but better in series order.
The newly married Duke and Duchess of Sedgwick are back home from their country estate and hope to resume a peaceful lifestyle, in particular now that Harold is recovered from his illness. Niall can go back to the forge and Kara her mechanisms.
It’s seems that a former enemy is back and while they decide to let Scotland Yard deal with the problem, it comes to them.
In a surprising twist, it seems that Petra is dead. Drowned in the River.
What a relief. They can return a calmer life.
Can they? Is she really dead?

Suspenseful and surprising and the danger edges closer. They must out-wit and plan and get creative to have any chance of winning the life and death pawn game.
Loved the references to the Great Exhibition and all the returning characters. A compelling mystery series.

I was gifted a copy from NetGalley and purchased a copy to keep.

I am going to go back and read the previous books in this series. Kara and Niall are unusual characters. They aren't what you would call an ordinary Duke and Duchess with their cobbled together family. They are loyal to the people they call family. When an old nemesis comes after them again, they try to stay out of it and let the police handle it, but it isn't possible to stay out of it. Petra will not leave them alone. She is bent on revenge and destruction at all costs. She doesn't care who gets hurt in the process. Kara, Niall and the others have to go after her and finish it this time. Can they finally put an end to her tyranny?

Betrayal From Beyond by Deb Marlowe is a Keir and Levitt mystery, book six. Niall and Kara are home after their wedding trip and adjusting to life at Bluefield Park as duke and duchess when things start happening. No one notices at first, but then it becomes obvious that Petra Scot, their old nemesis is lurking close by. Lord Stayme is being watched and the things escalate to actual contact. Then the constable calls them to see a body and, yes, it is indeed Scot, but things keep happening. Harold, their young ward has been progressing nicely and sometimes takes things on his own, such as spying. Very dangerous. They beefed up security at Bluefield and hunkered down to figure out what Scot is up to. With some investigating they discovered that she had a twin sister. Next on the list is to figure out what she is up to. And what a doozy it turns out to be.

Kara and Harold were working on automatons, Niall was forging gates, and Gyda had been traveling to London often where she had developed a relationship with the fourth son of a duke who shared her interest in creativity and together they were opening a gallery featuring both traditional art and craftsmen of all types. Sadly that ended in tragedy as Petra Scot arranged an attack which went awry. These are interesting characters who have gotten better as Niall and Kara have gotten together. The mystery was good, although quite a chase after a psychopath. People got hurt but Petra didn’t care so long as she met her objective. She didn’t.

I was invited to read Betrayal From Beyond by Dragonblade. All thoughts and opinions are mine. #Netgalley #Dragonblade #DebMarlowe #BetrayalFromBeyond

Will Petra Scott ever give it a rest?

Deeply ensconced in her determination to bring down Kara and Niall (now the Duke and Duchess of Sedwick) Petra’s nefarious plans have far reaching consequences.
A body is fished from the river. It is Petra Scott.
Kara feels somethings not quite right but it is definitely Petra.
So what’s Kara feeling uneasy about?
Danger and tragedy surrounds the couple and their friends as they work their way through a mass of lies, falsely laid paths, realities and counter truths.
An edge of the seat read from Marlowe that had me glued to my screen!

A Dragonblade ARC via NetGalley.
Many thanks to the author and publisher.

Tropes: MC's continue to pair up to solve a mystery
Steam level: 1 (all intimacy is closed door)
Part of a series, and best if read in order.

Another solid book in this series. Niall and Kara have returned from their honeymoon, only to have an evildoer from their past reappear and wreak havoc with their lives and that of their friends and family. They must consistently stay one step ahead of this person in order to survive and finally get justice.

The plot is the star of this entry. It's twisty and faced-paced, requiring a bit of suspension of disbelief at times, but the writer is adept enough to pull it off. The downside? Little time for romance. Niall and Kara have always had good chemistry, but their relationship is not the focus of this book. In fact, all of the relationships in general are subplots. There is an emotionally moving storyline in the early chapters involving a young woman who was exploited, but everything speeds off after that.

With action so prevalent, some nuances of characterization do get lost in the shuffle. And I honestly felt like Gyda got short-changed. She finally got a chance at a (unexpected) relationship, and then...well, I don't want to give away any spoilers, but I was a little bummed. Stayme is probably the standout of the secondary characters, injecting the proceedings with a nice dose of humor.

Although I enjoyed this entry, I would like the next book to refocus on Kara an Niall's relationship and move away from the storyline that was the hub of the previous book and this one.

I really thought this series had come to its conclusion with Niall and Kara's wedding and the moving ending of the last book, but I'm delighted to be wrong and the story of the likable and dynamic duo and their found family continues! As always, the plot is gripping, very well written and full of suspense, action, twists, danger, deception and a vicious adversary to keep the readers on their toes.

Kara and Niall, newly minted Duchess and Duke of Sedwick, have just returned from their honeymoon, when their old enemy, Petra Scot, reappears and starts her game of vengeance, intrigue and deception. Kara and Niall have their hands full trying to protect themselves and their family and thwart Petra's dangerous plans...

Overall, a riveting Victorian mystery romance with very likable main and supporting characters that will keep you hooked until the last page!

I received a free ARC of this book. Opinions expressed in this review are completely my own and left voluntarily.

The newly married Duke and Duchess of Sedwick are more than happy to settle in and enjoy a bit of peace, until it becomes clear that an old enemy has returned with a view to torment them. This time, they vow, they will let Scotland Yard and the government handle the situation. They are vastly relieved, then, to hear that their nemesis—a woman who has vowed vengeance on them both—is dead or is she?
The sixth outing for Niall & Kara & another fast paced intriguing book. I love the chemistry between the couple who are now happily married, they totally complement each other. There was intrigue, danger, conflict, drama & action & once again I found it hard to put down. The climax is thrilling & there’s plenty of suspense. I love this series & hope there are many more

This sixth book in The Kier and Levett Mystery series is another dast-paced, well written historical romance, mystery that I think should be read in order because it has many continuing thread previous books thst are also very good. The combination of action, drama, intrigue, suspense, conflict, amd many twists, and turns kept me very engaged. The return of the undoing villain is intense. I enjoyed the sweet scenes of their enjoyment being newlyweds, family time, and their love. I highly recommend reading!

A fast-paced mystery, as we have leaned to appreciate in this series. Although, I wouldn’t mind a bit longer description of the domestic bliss. The couple is constantly in danger (looming or active). They did seem to have had a quite honeymoon, but we weren’t invited, so that the new mystery, which is introduced in the first chapters, makes us miss the settling-in- and- enjoying- the- married -life part. Having read all the previous installments, the mystery was gripping but I did find the tone of the narrative rather pompous. It always was, but maybe it just wore out its charm for me this time.
Hope, the two recuperate a bit before the next disaster strikes.
I received an arc from netgally. Thanks! Opinions are my own and I left the review voluntarily.

I’ve enjoyed this series, but I’d warn any reader that there is very little explanation of what had gone before. You’re just thrown into a storyline which was quite convoluted across five previous books. I’m not sure how much new readers will understand of the relationships and backgrounds of these characters. The villainess was so indescribably evil with little care whom she murdered or destroyed. It was hard to take when nice and interesting characters were killed off. I enjoy the pairing of this couple, now a married duke and duchess, but I find it all quite unbelievable. But if you’re willing to suspend disbelief and muddle through reading until you understand the characters, you will enjoy the tension built up throughout the story.

I voluntarily reviewed an advanced reader copy of this book that I received from Netgalley; however, the opinions are my own and I did not receive any compensation for my review.

I really, really enjoyed this! But for the sake of full transparency I only realized that it was a part of a series after I added it. But that is ok, the mystery plot was easy to catch up with. I will come back to this book after I actually catch up to the entire series, which is lucky available on KU.
