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 – where everyone knows everyone, at least by sight – and with subtlety and sympathy, explores the intricate layers of truth and falsehood that can coexist in one moment of history.

Full of echoes, allusions and eerie diversions, A Granite Silence is an investigation into a notorious true crime case, but also a stylish, imaginative inquiry into who gets to tell a story, how it is told, and why.

When Frank disappears, Rachel is forced to seek help in the form of Robin, a private detective who left the police force for reasons she will not reveal. Like Frank, Robin is obsessed with the music of Bach. Like Frank, she has unexplained connections with the criminal underworld of southeast London.

An obscure science fiction story from the 1950s appears to offer clues to Frank’s secret agenda, but not to where he is. As Robin and Rachel draw closer in their search for the truth, they are forced to ask themselves if Frank’s obsession with an alien war, against all logic, might have a basis in fact.

Nina Allan’s new novel is a work of the greatest imaginative power, an investigation of the human need to make connections, to find causes and effects, however fantastic. Conquest is the story of a disappearance, and of the mystery that follows.

Starting work on her new project – photographing murder houses – she returns to the island where she grew up for the first time since she left for Glasgow when she was just eighteen. The Isle of Bute is embedded in her identity, the draughty house that overlooked the bay, the feeling of being nowhere, the memory of her childhood friend Shirley Craigie and the devastating familicide of her family by the father, John Craigie.

Arriving at the Craigie house, Cath finds that it’s occupied by Financial Analyst Alice Rahman. Her bid to escape the city lifestyle, the anxiety she felt in that world, led her to leave London and settle on the island. The strangeness of the situation brings them closer, leading them to reinvestigate the Craigie murder. Now, within the walls of the Craigie house, Cath can uncover the nefarious truths and curious nature of John Craigie: his hidden obsession with the work of Richard Dadd and the local myths of the fairy folk.

The Good Neighbours is an enquiry into the unknowability of the past and our attempts to make events fit our need to interpret them; the fallibility of recollection; the power of myths in shaping human narratives. Nina Allan skilfully weaves the imagined and the real to create a magically haunting story of memory, obsession and the liminal spaces that our minds frequent to escape trauma.
