Buried deep in the woods lies a secret map that leads to an artifact, written in code by a lumberjack who worked at Point Beach in 1939. As the mystery unfolds, Dominic, Forest, and Sailor are on the case, but they're not alone. A local taxidermist is hot on the trail, looking to add the artifact to his peculiar collection. Or is he? Ranger Rick offers little help with the distractions of a pesky bear on the loose, and the flirtations of Sally, the new park ranger. The race is on to the finish line. It's up to the young detectives to crack the code before the map ends up in the wrong hands.
