"Papa is very patriotic," brags Grant. "Mimi says he was a strong constitution," adds Christina. But the Constitution in jeopardy is the real U.S. Constitution! Is it lost? Stolen? Fake? Real? And how are they supposed to know! It's a spy vs. spy kind of mystery as Christina, Grant and their new red, white and blue (or are they spies too?!) friends follow the Constitution from its historic birth to its possible demise. "We have to save it!" Grant insists. "But how?" Christina worries. "Time is running out, we're being chased, and ohmygoodness look at that!" Join them for some mysterious fun, a "capital" tour, parade pandemonium and really, WILL THEY, CAN THEY SAVE THE CONSTITUTION?! Each mystery incorporates history, geography, culture and cliffhanger chapters that keep kids begging for more! Each mystery includes SAT words, educational facts, fun and humor, built-in book club and activities. Each Carole Marsh Mystery also has an Accelerated Reader quiz, a Lexile Level, and a Fountas & Pinnell guided reading level.
