Aunt Murgatroyd is back to challenge potential problem solvers with more riddles, puzzles and problems! This time the Troublemaking Trolls are after the Domesday Book! (Pronounced Doomsday!) But don’t worry, it’s not as scary as it seems. The book is an 11th century census of Norman, England! Can you help Aunt M. defeat the trolls and save this invaluable treasure trove of historical data?
