解開“彌賽亞小提琴”之謎

The “Messiah Violin” was the most expensive violin in the world. But it had been called a fake.

The famous tree detective， Dr. Henri， was on the case.

The violin was worth $20 million because the master instrument-maker Antonio Stradivari crafted the instrument more than 200 years ago.Or did he? A scientist who studied violins and another scientist who studied tree rings claimed that Stradivari did not make the violin. It was not

possible， they said， because the last ring in the violin’s wood had grown in 1738. That was the

year after Stradivari died.
