Peter read your book. I enjoyed the puzzles. I especially enjoyed your scathing comments on travel, politics and society.
One puzzle I don't get. What do you call a man with a plank on his head? Edward.....????? Must be a British thing. mirtim@bellsouth.net

I read this book over a weekend, and it definitely held my attention. I always enjoy a good thriller, and this definitely fit the bill. Enough humor, action, twists and turns to keep you going.

A cracking fast moving thriller that will have you hooked in an instant.
The plot is a straight forward good guys bad guys race against time, but with a twist as even the good guys have to figure out where to go first.
This very enjoyable novel will also introduce you to the intriguing and sometimes mysterious world of geocaching.
Make sure you have a few hours free as once started you won’t be able to put this one down.

A real page turner - I started this on a Friday evening and finished it the following morning. This is a straightforward thriller with a plausible plot, with no holes that I spotted, that fairly rattles along to a satisfying conclusion.

Kept looking at this book as it sat on the coffee table, then after Christmas picked it up. Was soon addicted and couldn't put it down!! All read in two days flat!! An exciting thriller mystery. Highly recommended.

An intriguing thriller by a new writer, set in the south of England, involving the increasingly popular pastime of Geocaching. Fast moving, action packed, as the heroine struggles against a deadly foe to solve her dead father’s puzzles in a race to save his planet saving eco-invention. Not to be missed.

A great first novel from this exciting new talent. A skillful blend of modern topics like destruction of the planet, the credit crunch and terrorism, with a few interesting puzzles to solve along the way.



OK, I admit it, I wrote it, so I'm biased!

Just finished the book and found it an interesting read. Definitely a pacy thriller involving murder, mystery and intrigue combined with Geocaching! (Quite brought tears to my eyes at one point). And, it also clarified one or two diagonally challenged questions I had about the puzzles! Well done.

An easy read, like Dan Brown without the sales volumes and with a slightly more down-to-earth context (the heroine is daughter of a University professor in Surrey rather than a descendant of Jesus). Ideal for a plane journey. Armstrong uses the new, if slightly nerdy, hobby of geocaching to create a pacy thriller with neat puzzles and tongue-in-cheek soap boxing about the ills of the modern world. Buy it and see for yourself, or take up geocaching and you might find a copy in a geocache down in the SE of England.
