One warm July night, when thoughts of Ireland are far from James Dwyer’s mind, a homeless man with a sunburnt face, who smells like dry wood, comes to the screen door of his Michigan apartment. Walter has two messages. The first is that an old lady is lying in the middle of his street. But when James goes to look there’s nobody to be seen. The second, while apparently more ordinary, is ultimately more troubling: a childhood friend wants him to visit. Kevin Lyons, the wayward older son of a neighbouring builder James knew long ago as a boy in Tipperary, now lives in the USA too, and wants to reconnect with his past. But James, who has spent years establishing the foundations of his American life, has put that past behind him.
