Swindle mystery

"The multimillion-dollar Star of Prague has been stolen from the top of the tree at Cedarville's annual holiday pageant, and The Man With The Plan is the prime suspect. Now Griffin and the team have to solve the mystery and catch the real thieves just to clear their names and avoid being Scrooged!"--Author's website.

After a class trip to a floating zoo where animals are mistreated and Savannah's missing pet monkey is found in a cage, Long Island sixth-grader Griffin Bing and his band of misfits plan a rescue.

"Luthor the Doberman, a former attack dog, has a good home with Savannah Drysdale, but every time a certain truck passes he goes into a frenzy, while Griffin Bing is caught up in trying to beat his rival, Darren Vader, at an invention contest."--Provided by OCLC.
