Secrets of the silver lion

"For centuries, the magnificent Throne of Felipe has stood with two empty spaces beside its famous silver arrow'spaces where the silver castle and lion should have been. And now, with the recent discovery of the silver castle within a secret vault in Seville, Spain, the hunt is on for the third silver icon. With all three pieces in the place, the throne will be enormously valuable'making it a hot item on VILE's radar. Now it's up to Carmen and crew to find the silver lion before VILE does, and protect the throne from winding up in the wrong hands"--OCLC.
