Berlin, 1939. A young, brilliant trumpet-player, Hieronymus, is arrested in a Paris cafe. The star musician was never heard from again. He was twenty years old. He was a German citizen. And he was black.Fifty years later, Sidney Griffiths, the only witness that day, still refuses to speak of what he saw. When Chip Jones, his friend and fellow band member, comes to visit, recounting the discovery of a strange letter, Sid begins a slow journey towards redemption.From the smoky bars of pre-war Berlin to the salons of Paris, Sid leads the reader through a fascinating, little-known world, and into the heart of his own guilty conscience.Half-Blood Blues is an electric, heart-breaking story about music, race, love and loyalty, and the sacrifices we ask of ourselves, and demand of others, in the name of art.
