Minnie is the orphan child of a decaying estate, educated in England by an emigrant uncle, and returned to live with a decaying uncle and Ivy, the housekeeper. She's only just into her teens, and Johnston does a very credible job of creating her confusion and frustration and dreams. She also clearly creates the Kelly family, paragons of poverty, drink, violence. The weak spot is Minnie's parents. They almost non-existent, and it isn't surprising that the family isn't forthcoming with information, but what little the girl gets isn't made sense of at all. Everything else is so tight that the stray ends are obvious. Kevin Kelly, the oldest of eight, is desperate to escape his lot, loathes his father, and hates his mother for allowing herself to be beaten, as he sees it. Kevin, uneducated and unwashed, is Minnie's crush. When the heritage tourists come with their American dollars, Minnie and Kevin concoct their plans. Johnston crafts the characters and their circumstances so smoothly and convincingly that when the end comes, who could hate Kevin for what he does? Not me. Not Minnie.
