Coventry and Brixton in the 1980s. My guest this week has drawn on reggae and the music of the iconic Two Tone label to evoke cities riven by racial conflict. Music was a strong part of identity and hers is a soundtrack of jagged horns and simmering beats. Her novel’s title echoes one of Two Tone’s landmark tracks – Ghost Town, by The Specials. If you know it, I bet it’s started in your head – and hold that thought, because she returned to the track time and again to capture her characters’ tensions. She is Catriona Troth and she’ll be here on Wednesday with her Undercover Soundtrack.
