A journey through time to a particular house, in a particular street, Urquhart Road, Aberdeen in 1934, where eight-year-old Helen Priestly lives with her mother and father. Among this long, grey corridor of four-storey tenements, a daunting expanse of granite, working families are squashed together like pickled herrings in their narrow flats. Here are Helen's neighbours: the Topps, the Josses, the Mitchells, the Gordons, the Donalds, the Coulls and the Hunts. Returning home from school for her midday meal, Helen is sent by her mother Agnes to buy a loaf from the bakery at the end of the street. Agnes never sees her daughter alive again. Nina Allan explores the aftermath of Helen's disappearance, turning a probing eye to the close-knit neighbourhood and with subtlety and sympathy, explores the intricate layers of truth and falsehood that can coexist in one moment of history.
