This is book number 45 in the The Boxcar Children Mysteries series.
An orchestra is coming to town! The children are excited to hear the orchestra play, to meet the musicians, and to learn how to make their own instruments. The orchestra is also displaying a very valuable, old piece of music. But when it mysteriously disappears, it’s up to the Boxcar Children to find it!
The Boxcar Children series was created by Gertrude Chandler Warner, a teacher, when she realized that there were few, if any, books for children that were both easy and fun to read. She drew on her own experiences in writing the mysteries. As a child, she had spent hours watching trains near her home, and often dreamed about what it would be like to live in a caboose or freight car. In each story, she chose a special setting and introduced unpredictable, unusual or eccentric characters, to help highlight the Aldens’ independence and resourcefulness. Miss Warner lived in Putnam, Massachusetts until her death in 1979.
