If you liked the DaVinci Code, you will probably like this one. Not as well written, but enjoyable.
Description: Stranded in Milan by a train strike, a down-on-his-luck music scholar finds a misterious document at an auction. Could it be the diary that Mozart kept as an adolescent, traveling through Europe with his father? If authentic, the diary could catapult Matthew Pierce into wealth and fame. His search for the truth leads him into a dazzling world of Europe's most gifted musicians and wealthiest aristocrats. But the brilliance of his surroundings is clouded by intrigue, threats, and murder.
