About the author

Award-winning author Russell Atkinson served as an FBI Special Agent for 25 years, where he specialized in high-technology crimes in Silicon Valley. He was the first to investigate Raj Rajaratnam, the high-tech hedge fund manager who was convicted of insider trading in 2011. He was the case agent on the first federal prosecution in California under the Economic Espionage Act. He worked on several kidnapping cases and has arrested murderers and drug dealers. After retiring from the FBI he practiced law. With degrees in mathematics and law he worked for many high-tech firms in the computer industry including IBM, Fairchild Semiconductor, and AOL. He served as President of the American Cryptogram Association and has written extensively on cryptographic topics. He was Head Cryptographer for the movie The Red Machine, which was given a thumbs up by Roger Ebert. Now retired, he lives in Silicon Valley and spends time with his interests: running, geocaching, guitar, cryptography, and, of course, writing.

Regardless of whether one is a geocacher or not, this novel stands on its own. The story is fast paced, the situations plausible, and the characters are interesting. It is a real page turner. It is, truth be told, one of the few books I have read (and I read a lot) that I did not want to put down. When I got to the end, I wanted more. If it was a TV show I'd already be checking the schedules waiting for the next season to start.
Geocaching does play a central part in the story, and it is intricately woven into both the plot and the character development. However, the geocaching is explained enough that I believe someone who is not familiar with geocaching would have no problem following the story, in the same vein as one does not have to be a lawyer to understand or enjoy a John Grisham novel.
That leaves us with the question of the accuracy of the geocaching. I am an avid geocacher, and I am also rather pedantic. Inaccuracies in caching descriptions quickly cause me forget about the story and concentrate on the errors. As a result, accuracy is vital for my enjoyment of a geocaching themed book. Fortunately there is good news on this front.
The author of Cached Out is a geocacher himself, and it shows. His depictions of geocaching are, essentially, perfect. Both descriptions of geocaching itself, and how the geocachers think, are exactly what I expect based on my extensive experience with geocaching and the geocaching community. Many times during the story, and especially during the climax, I thought "yep, that is *exactly* how a geocacher would react." As a result I found that the geocaching in the novel allowed me to get more enjoyment out of the story. Think of it like a delicious gravy spread over Thanksgiving dinner.
So, in summary, as a murder mystery novel it is a good read, fun, quick paced, and enjoyable. As a geocaching themed novel it is even better. It would make a fantastic stocking stuffer for the geocacher on your Christmas list.
That said, I'm a geocacher and that aspect of this book was extra special to me... so if you like to read AND you're a Geocacher, this is a DO NOT MISS item for you!!
BTW, if you do want to do the puzzles, DON'T read further in the book until you have solved them as they do get explained, usually in rather short order.
Did you notice the past tense verbs I used in the paragraph above? There is a reason for that. If I were writing this review after having read the first hundred pages or so, I would definitely award five stars to what I'd be happy to call an excellent read. Unfortunately, a few serious problems develop in the second half of the book.
One, it goes on far too long. If the author had disciplined himself to edit this story down to 60% or so of its current length, it would have been a better product. Whole subplots are introduced that do little towards advancing the storyline. Two, a book that had been refreshingly light on bad language had some of its main characters turn into potty mouths toward the end. However, the biggest flaw in my opinion comes with the resolution of the story. I can't deal with specifics without spoiling the outcome so I'll simply say that the ending was highly unsatisfying. The reader feels frustrated because justice was not done.
I am disappointed. What should and could have been a five-star book really deserves no more than two or three. Remembering the first part of the book, I'll be generous and give it three. The jury is out for me about whether or not I would be interested in giving Atkinson's work another chance.

I really liked the writing style, interesting storyline and likeable main character. Plus it's rare to see Geocaching included in fiction this way.
I've since purchased the other six Cliff Knowles books as they all make for enjoyable reading - well recommended.
My only criticism was the continual acronyms used; they may have been necessary, but annoying all the same.
The story line was great as were the characters, some likeable and some not. Can't wait to read the first book.
