The story takes place in Drummond Castle, the Alden family has been invited by Grandfather's friend, Carrie Bell, to help turn the old home into a museum. When the Alden children learn that a Stradivarius violin owned by the original Mr. Drummond has disappeared, they work together to find the missing instrument.

Great book for any one who loves to solve mysteries. Also, it allows kids to think cratively.

Teachers can have class read book and write a book report on it. Also, teachers can have kids read half of the book and have kids write down what they think happens in the end. ( )
