When you have a secret past, it’s only a matter of time before it catches up to you.

Officer Wyatt Davis thought he left his old life behind—until a sinister message forces him into an impossible betray his own values or let the people he cares about suffer.

But Wyatt isn’t the only one haunted by the past. Someone else in town is running from old ghosts—a fierce survivor with secrets of her own.

As a dangerous federal agent watches his every move and unexpected alliances begin to fracture, Wyatt doesn’t know who to trust. Wyatt knows that sometimes those who seem like good guys turn bad, kind of like the new mayor of White Rock, Henley Jamison.

Meanwhile, Jo and Bridget are settling in with Pickles, but they still refuse to believe their sister will never be found. Bridget and Kevin’s relationship is growing stronger—but so is the storm brewing around them.

And when a new dog arrives who seems to share an instinctual bond with Lucy that hints they may have a shared past, it becomes clear - the past never stays buried.

At least, not for long.

I have been following this series now for some time and am blown away by the amount of secrets you can fit in such a small rural setting and their police force. Hiding Crimes by L.A. Dobbs is the tenth book in the Sam Mason series and in this one we get a lot of answers that I as a reader has been waiting for. As an old beer comercial put it, "It was worth the wait". Now after reading this book I have a new set of questions and I was therefore glad to see that book eleven is already announced. I can't wait. I don't know much about other books by this author but she has a few different series under a few different pen names, and I bet they are just as well written as this series. I will however find myself content with following Sam since I don't have more time for reading. I will recommend this series for fans of well written small town mysteries and a great setting with marvellous characters. She even has a dog and a cat that plays an important part in the adventures.

secrets are hard to keep

Another dead body, this time it’s a warning, we’re watching we’re near and anyone can die. The group has secrets and they need to share, but fear and self loathing hold them back. Now 2 FBI agents show up, and the group is watching each other, can they trust each other, or will it get worse if they do or worse if they don’t.

Another great story by Ms Dobbs, I truly enjoyed this one. Couldn’t put it down now I’ll wait for another one if she writes about this family of cops. Great read my favorite so far.

Ms. Dobbs does it again!

These Sam Mason books are fantastic, there's never a dull moment! I like that Major and Lucy are in this book a lot, their relationship is always fun to read.
I don't want to get into the plot of the book, I'd rather not leave any spoilers, but I will say it is a fast based book with lots of surprises, and action, I didn't suspect the ending which made it more exciting. I hope that there are more adventures with Sam Mason and his crew to come our way, I can hardly wait for the next one to come out!!

Good (not great) read

I find the characters in this series engaging and it starts with a shocking discovery. But many things seemed repetitive: the cat on the filing cabinet; the sights, sounds and smells (burnt coffee) of the police station, cars pulling up next to another character’s ride are mentioned over and over again. I will probably dive in again when the next Mason book comes out to see how the relationships progress.

Hiding Crimes is the 10th book in Sam Mason Mystery series by L.A.Dobbs.

This is an excellent K-9 Crime series.

This book was so good, I could NOT put it down.

This story is personal for the members of the team, Wyatt, Kevin, Jo, and Sam.

There are many layers to the story and some shocking twists and turns.

The ending was so good.

This is a great story with great characters.

Another fantastic book in the Sam Mason series!
This book delves into Wyatt's backstory, and why he's always so secretive about his past.
Two seperate FBI agents arrive to investigate the murder of an undercover agent.
Is anyone telling the truth?? Who can Sam and K-9 Lucy count on as they come up against a crime syndicate?
So many twists will keep you guessing and second-guessing until the very end.
I'm really hoping there will be more, I really want to get Lucy's full backstory.

This is the tenth book in the Sam Mason Mysteries. Deputy Wyatt Davis’ back story is revealed. \We learn why he has been so closed lipped and secretive.

His father has found him and wants to use him for illicit gains. I was on the edge of my seat. I recommend this story. It can be read as a standalone.

I was given an advanced readers copy. These are my opinions. I am not required to leave a positive review.

This book gets 4 stars because I find this series to be consistently entertaining and easy to read, but I have to admit that the editing leaves something to be desired. There are a lot of repetitive phrases throughout and even a couple typos and blatant inconsistencies, but despite this, I’ll keep reading because the characters are enjoyable and the “whodunnits” are entertaining. Bonus, there’s a dog!

Excellent addition to the series

A dead body in Wyant's trunk that turns out to be an FBI agent, his father issuing demands, and a couple FBI agents show up at the station. Wyant is scared and afraid to trust. This is an excellent addition to the series, and I look forward to more as Wyant's father is still out there.

I like the Sam Mason & Lucy series a lot. This entry was good and I read it quickly, but it was a pretty straightforward tale. I expect the next one (or more) in the series will be more exciting given how the plot was slightly unresolved at the end of this one. Definitely recommend as an easy read with good characters.

An exciting book

A story filled with secrets, distrust, and excitement.
Sam's crew finds a body and all their world tilts. Who are they really? Is the trust you once had still there. Danger surroundings each of them in different ways. Add a couple FBI agents and mix stiffens.
But love blooms even in the turmoil.

Finally the truth is out!!

I got through the books about Sam Mason wanting to reach the union of the protagonists in an open truth.
Finally, as the title of this review says, they got to open up their souls and personal histories to a common ground.
Obviously, the fall of the gang head is still in the air.
Thank you Ms. Dobbs for a superb story.

The cases build and the characters develop. With each book the same core characters take on crime in their small community. Character development improves and broadens with each book. Besides the human characters, there are 2 cats and a dog, with distinct personalities and interactions with each other and their human partners. A fun read!

Simple story...deep reality

This crew is easy to care about. Sam, Jo, Lucy...the whole bunch are so real, ordinary, doing the right thing. Proving that when life gets tough it's people who matter. Intrigue woven through it all. Mystery, suspense. Very entertaining.

Sorry to see the end of this series, there seems to be much more that can be done with these characters. The book was well written and flowed by quickly. The ending was a bit of a surprise and some loose ends seemed to be left.

Great next chapter

The story of Sam Mason, Lucy and his sheriff's office continues in enjoyable fashion. The tenth book is as well-written and holds the reader's attention as well as the first.

Great read!

The Sam Mason series is wonderful. I love the characters and how they work together to keep their "family" safe. Lucy brings it all together with her dog wisdom and love for them all.

gut churning suspense

Wyatt comes home from a short stroll and finds an unwelcome sight, presaging reemergence of his haunted past.

Then two FBI agents appear, separately, neither one aware of the other.

I just love the Sam Mason series, I have been hooked from the very first book. The stories just flow and grab you immediately. The dog Lucy and all the characters seem real and their relationships are enviable. I sure hope there is a #11.
