Alex Kotler has always been good at solving mysteries. That's why he started his own detective agency—any mystery solved, but it will cost you a buck.
For one dollar, Alex finds lost homework, helps track down missing bicycles, and puts things right for kids who need a little help. But one day, a new girl in town brings Alex an all new sort of mystery. Her father has a mysterious diamond sword—and it's gone missing!
Alex has to use all of his smarts (and everything his famous uncle, Dan Kotler, has taught him) to track down the diamond sword and unravel its mysteries. But he's not the only one looking.
Can Alex solve the Secret of the Diamond Sword, escape capture by the mysterious man who took it, and collect his buck?
