This is a story about a young Negro musician, who returns to the USA after the years that he had spent abroad learning to play the violin and giving concerts in different European cities. The action of the story takes place in 1932 in the USA. This was the time of the world economic crisis.

Roy Williams had come home from abroad to visit his mother and sister and brothers who still remained in his native town, Hopkinsville. Roy had been away seven or eight years, travelling all overthe world. He came back very well dressed, but very thin. He wasn't well.

It was this illness that made Roy come home. He had a feeling that he was going to die, and he wanted to see his mother again. This feeling about death started in Vienna, where so many people were hungry, while other people spent so much money in the night clubs where Roy's orchestra played.

In Vienna Roy had a room to himself because he wanted to study music. He studied under one of the best violin teachers.

"It's bad in Europe," Roy thought. "I never saw people as hungry as this."

But it was even worse when the orchestra went back to Berlin. Hunger and misery were terrible there. And the police were beating people who protested, or stole, or begged.

It was in Berlin that Roy began to cough. When he got to Paris his friend took care of him, and he got better. But all the time he had the feeling that he was going to die. So he came home to see his mother.

He landed in New York and stayed two or three days in Harlem. Most of his old friends there, musicians and actors, were hungry and out of work. When they saw Roy dressed so well, they asked him for money.

"It's bad everywhere," Roy thought. "I want to go home."

That last night in Harlem he could not sleep. He thought of his mother. In the morning he sent her a telegram that he was coming home to Hopkinsville, Missouri.

"Look at that nigger," said the white boys, when they saw him standing on the station platform in the September sunlight, surrounded by his bags with the bright foreign labels. Roy had got off a Pullman – something unusual for a Negro in that part of the country.

"God damn!" said one of the white boys. Suddenly Roy recognised one of them. It was Charlie Mumford, an old playmate – a tall red-headed boy. Roy took of f his glove and held out his hand. The white boy took it but did not shake it long. Roy had for- gotten he wasn't in Europe, wearing gloves and shaking hands with a white man!

"Where have you been, boy?" Charlie asked.

"In Paris," said Roy.

"Why have you come back?" someone asked. "I wanted to come and see my mother."

"I hope she is happier to see you than we are," another white boy said.

Roy picked up his bags, there were no porters on the platform, and carried them to an old Ford car that looked like a taxi. He felt weak and frightened. The eyes of the white men at the station were not kind. He heard someone say behind him: "Nigger." His skin was very hot. For the first time in the last seven or eight years he felt his colour. He was home.

Roy's home-coming concert at the Negro church was a success. The Negroes sold a lot of tickets to the white people for whom they worked. The front rows cost fifty cents and were filled with white people. The rest of the seats cost twenty-five cents and were filled with Negroes. There was much noise as the littl
