An auction bid presents an old suitcase with cross-swords and a skull, so, naturally Steve bids on it. It turns out that there was an old map hidden in there of The Grim Reaper's Mine. Suddenly, the Decoders must configure the cryptic poem and seek the answers behind the mysterious papers.
Could there still be gold in that old mine?
Through research ,the kids find out the legend of The Magic Sapphire and the power it supposedly gives to whoever owns it. Interesting. Only a good person can find the stone. A real live treasure hunt!
Can they find the treasure before the jewel thief does?
This is another fun adventure book. It seems like these kids are always figuring out a code and going on a treasure hunt, making most of the books in the series pretty much the same. The bulk of the story is the actual decoding―going line by line, analyzing each lame text, to figure out the special meaning.
Still, these kids are smart and witty, and young readers will enjoy this little tale.
My rating: 3.5 stars
