The island of Olib in Croatia .... peaceful, beautiful, until it isn't .....

Rex Dalton and his amazing dog Digger are visiting, when another visitor,a young lady is found murdered. The police charge another visitor almost immediately ... but Rex and Digger don't believe it for a minute.

Dalton decides to conduct his own investigation and bring the real killer to justice.

This is a very short story (48 pages) filled with action, mystery, and quirky residents. If you have followed this series, you will like it. If not, this would not be ny recommendation on where to start. There is not a lot of character development, but it does whet my appetite to go back to the beginning of this series to see what I've missed.

I love the relationship of man and dog.. I found it very much entertaining. The two old women who serve as the Island's Customs invent stories about the visitors to anyone who will listen are a hoot.

Many thanks to the author for the digital copy of this short story. Read and reviewed voluntarily, opinions expressed here are unbiased and entirely my own.

No doubt, the most exciting short story I've ever read!!

Mystery and intrigue on a tiny island no doubt kept me hooked.

A mysterious man and his very obedient and talented dog quietly navigate the island as the locals assign motives and speculation on those arriving off of the ferry....

Fans of Don Pendleton's Mack Bolan, Able Team and Phoenix Force Series' will feel right at home with this series.

I received a free copy of this book through an email from JC Ryan and I have No doubt I'll be buying and bingeing the entire series!!

This was a good read as our intrepid hero and his faithful sidekick solve a crime. It wasn't the masked man and Tonto, but equally effective. They just missed witnessing the murder and could immediately put together the facts. The story leads us through the eyes and vision of a remote witness to all as we tail the hero and sidekick.

They have plenty of resources available and they do use them.

Rex Dalton series:
No Doubt - I read The Fulcrum (#1) before I read this short story. I enjoyed the writing style of the beginning chapters and the presentation of the island's natives and tourists. Quite comical until the murder, then the style changed similar to The Fulcrum. There's a bit of maturity in the character and dialog missing in this short, but it's still an interesting and entertaining story. This is introduction to Rex and Digger's histories, as well as bits and bobs about Rex's purpose for being on the island. The Fulcrum actually did a great job with Rex and Digger, which makes this short unnecessary, but still a good read. 4*

The Fulcrum #1 - My first read by this author and I couldn't put the book down! Mesmerized by the writing style, the vivid descriptions and the storylines, I read without stopping. Fast paced, action packed and interesting on several facets. Rex is a good example of what many Americans used to be, the masses who made this country great. Now after the decades of the Dark State (read chapter 15 for clarification) at work molding the brainwashed and dumb downed younger American generations with Mickey Dees and smartphones, our future and security is at stake. This is not a political agenda on part of the author, but part of the description of what we're facing; the reasons Rex became driven. The truth of what we're actually facing with cartels, terrorists and the havoc and destruction caused by the corruption and ineptness of our government's screaming chimps. Oh, sorry, our politicians.

I thought our Founding Fathers voted English (by one vote over German) as our Country's language? A point that caused me concern was his blacking out and thinking he was rescuing his sister. Not sure he would have been allowed to continue, but I'm not in that world and maybe he has special talents that were in dire need. As for mental testing, as determined as he was, he probably had the ability to pass them. Of course there's clarification later concerning those tests. While the ending was not a cliffhanger, the job was accomplished, plus; the ending gives the opening to the next book of the series. Ludlum is my favorite author, but I've found another one that I look forward to reading more of his work. The only editing needed was Internet, somehow everyone thinks this proper noun and place is lower case. I found this book on authorsxp.com. 5*

The Power of Three #2 - I absolutely enjoy this author's books. If you're Ludlum and company fan, you will like Ryan, too. If you haven't read The Fulcrum, the first book, it isn't necessary since this book gives background from the first. But I recommend reading it anyway; it is a good foundation for the series. Well written, fast paced with intriguing and suspense filled storylines.

The characters range from good to despicable, with many characters from the previous book. The emotions run the gamut. The terrible truth about America's governing leaders will dishearten many, but there's still hope the Dark State won't win completely. After all, not all Americans want donuts and circuses; the proof of that lies with the current elected president, instead of the increased circus clowns being elected.

The relationship between Rex and Trigger develop, but at a great cost to both. Part of the cost brings Rex to make decisions about their future and leaves possibilities of multiple paths to be taken in their journeys. While not a cliffhanger, the story is complete, but the series does continue. There's an overview, which I appreciate knowing what a story is about before I read nowadays. I contacted the author to review his books and found this book on authorsxp.com. Minor editing needed. 5*

Unchained #3 - As good as all the other books were, this one tops them. Mr. Ryan has become one of my favorite (new) authors in my all time favorite genre. This is another well written and fast paced adventure. The intrigue and planning to make all come together is great. Everything is realistic and there's no "Hollywood poof" to make things work; the storylines have been planned and well thought out. The characters are developed as much as their roles need them to be. The main characters, of course, continue to grow in their roles as the storylines continue. The vivid and clear descriptions do not leave the reader confused or hanging, but involved with the happenings. The travels are interesting in themselves. Rex and Digger are getting better with their relationship; and Rex is gathering a family of friends to end his days alone. Both kept growing as the pages flew by. I contacted the author to review his books and received this one through AXP. 5*

Sideswiped #4 - I absolute enjoy this series and this book fits in like a charm. Fast paced and intriguing, this interesting addition keeps the reader immersed in the story until the last page. Again, we met good and interesting characters and glimpses into another culture. The characters run the gamut from braggart fool to criminal mercenary to doctors and more. The vivid descriptions place the reader in the mix and flow. There's maybe a touch of romance, maybe not, but ask Digger his opinion about that. The emotions don't run rampant as they did in Unchained, but there's enough to make the story work. I contacted the author to review his books. 4*

The Inca Con #5 - I can't wait to read a book from this series and I'm so lucky to have found this author after he released several books. I don't have to wait long to read the next one. In Peru, chasing history and finding a whole can of whoop*** keeps Rex and Digger in their roles as guardians for several different characters plus a village and their dying children. The duo are closed to married couple status finishing each other's thoughts; no traces of their earlier relationship since they've been together over a year. The storylines are interesting, the pace is steady and the action realistic. There's no stupidity, dumb dialog or Hollywood action scenes. A special character holds Rex's attention and she's not a dumb dame. Read these books in order for best value. I contacted the author a while back to review his books and found this book on AXP. 5*

The French Girl #6 - I love that the author always has an overview of the story at the beginning of the book. Get ready for a whirlwind journey from country to country with Rex and Trigger saving others, yet again. The beginning, for me, started a bit slow laying the foundation about France and the main players there. But once the story started rolling, the pace never slowed down. The story lines run amok with all the different characters and agendas that occur in this book.

The characters are still believable and developed enough for their roles, while there's more to Rex and Digger. The dialog remains realistic without any stupidity. There's plenty of emotions spilling out of the pages and the suspense is thick in many places. Mr. Ryan's vivid descriptions place the reader in the middle of the action and still leaves plenty for the imagination. Well written and well thought out, the series continues to grow in substance and leaves the reader wondering when the past is going to cross Rex's path. Rehka does wonders as Rex's girl Friday. I contacted the author to review his books. 5*

Olib, Northern Dalmatia, Croatia. Marija (older woman) & Agneza (coworker) were gossiping about a whore Lucija Babić from Zagreb out looking for a man to bewitch.
They were greeters to the tourists who got off the ferry’s, always stereotyping the island guests.
Sightseers would come across the St. Paul's Church & Monastery which was abandoned during the 13th century.
The harbormaster was 1st on the crime scene. The deceased was Lucija.
Dramatic turn of events in Olib Murder Case.

I do not receive any type of compensation for reading & reviewing free books from publishers & authors. Therefore, I am under no obligation to write a positive review, only an honest one.

An awesome book cover, great font & writing style. A very professionally written thriller book. It was quite easy for me to read/follow from start/finish & never a dull moment. There were no grammar/typo errors, nor any repetitive or out of line sequence sentences. Lots of exciting scenarios, with several twists/turns & a huge description list of unique characters, settings, facts etc. to keep track of. This could also make another great thriller movie, or better yet a mini-TV series. to be continued. There is no doubt in my mind this is an extremely easy rating of 5 stars.

A definite must read book and series

I absolutely love this series! Although I was very sad about what happened to Digger's original handler (sorry, I hate spoilers!), Rex and Digger are a perfect fit for each other. I really, really hope that there will be many more stories in this series in the near future!
This story was entertaining, humorous, with a bit of suspense that will capture you from beginning to end. You'll definitely fall in love with the adorable Digger, and of course Rex too. Lol! It's not a story that you'll want to miss!
I would definitely recommend this book, series, and outstanding author.

I found No Doubt (REx Dalton #5.5) a novella by J.C. Ryan rather boring.

A beautiful woman has been stabbed to death on an island where the harbour master replaces the police and a couple of old ladies who reside on the island act as informants because they have the knack of judging tourists who come to the island as to whom are decent and those who are not.

It is up to Rex Dalton a former black ops specialist and his trusty dog, Digger to sniff out the murderer.

A good short story.

Personally I am not a lover of short stories. I prefer to be enthralled in a good book for a few hours. However this is not a bad little story and for the uninitiated gives an idea of what Rex Dalton and his military dog, Digger, are all about.
Now back to a full story.

JC RYAN paints pictures with his words. He keeps me involved with every chapter.
I found this series to be an excellent thriller, a page turner. Its hard to put the book down once I start reading.
While the outcome may be predictable, there is enough intrigue to keep you wanting more.
The big winner in this series is undoubtedly the dog.

This short story about former black ops specialist, Rex Dalton, starts on the tranquil Croatian island of Olib. Until the peace was broken by the death of a victim, considered by many to have made herself vulnerable to murder. That’s when champions of the innocent and oppressed, Rex and Digger, become involved.

A really good short story. JC Ryan has put together a story that puts the reader on an island of Croatia where there is no crime, no police, and two women who assume the roles of immigration enforcement. They have a unique way of assessing the newcomers. A very rare crime takes place and Rex and Digger are on the job. Thanks for entertaining me for a short while.

‘No Doubt: A Short Story’ was captivating. The plot involved a lady’s murder, the townspeople’s inuendos and speculations, a man’s arrest, an innocent bystander investigating, a dog coming to his own conclusions, and a flash drive sent to the police. Additionally, I appreciated the author’s word choices, which created a suspenseful tone. Overall, I liked the narrative.

Justice once again.

I love these books with rex and digger making justice wherever they go. Robin hood like care for strangers. And digger is brilliant and a great canine sidekick. always an intriguing resolution to the current mystery.

I really enjoyed the premise of this story introducing Rex and his dog Digger. As a previous assassin, he and his dog are trying to travel the world, but seem to always get stuck in the middle of murder and mayhem.
I felt that character depth was missing, but still a quick, great story.

Digger, No Doubt

Digger will always find justice for those wrongfully accused of crimes. No Doubt was written in a different style than the former novels, it had the feel of an old-time radio mystery. Kudos to the author!

Entertaining short little read.

First time I read a story about this character. Apparently he's a ex-military contractor, traveling the world as sort of a modern-day paladin. His sidekick is his dog.

While on vacation in Croatia, help solves a murder while working behind the scenes.

JC Ryan is great in giving details of the scenery in the area where the story is being told and also on how Rex and Digger go about solving a crime. Great job JC. Keep it up. Will be reading the next in the series.

Unfortunately, I didn’t get much thrill out of reading this book. I generally like JC Ryan’s books and was disappointed in this one. There were several places where there were very long sentences which I felt affected the train of thought.
