Ghosts and spectres, the eerie and the occult. Why is contemporary culture so preoccupied by the supernatural, so captivated by the revenants of an earlier age, so haunted? The concept of Hauntology has evolved since first emerging in the 1990s and has now entered the cultural mainstream as a shorthand for our new-found obsession with the recent past.

Return to the world of Rivers of London in this first short-story collection from number one Sunday Times best-selling author Ben Aaronovitch. Tales from the Folly is a carefully curated collection that gathers together previously published stories and brand new tales in the same place for the first time. 

A writer has left his family in Brooklyn for a three-month residency in Berlin, hoping for undisturbed days devoted to artistic absorption. When nothing goes according to plan, he finds himself holed up in his room watching Blue Lives, a violent cop show with a bleak and merciless worldview. One night at a party he meets Anton, the charismatic creator of the show, and strikes up a conversation. It is a conversation that leads him on a journey into the heart of moral darkness. A conversation that threatens to destroy everything he holds most dear, including his own mind.

Shaw had a breakdown, but he's getting himself back together. He has a single room, a job on a decaying London barge and an on-off affair with a doctor's daughter called Victoria, who claims to have seen her first corpse at age 13. It's not ideal, but it's a life. Or it would be if Shaw hadn't got himself involved in a conspiracy theory that, on dark nights by the river, seems less and less theoretical....

A story at once mythic and strikingly timely, Sarah Moss's Ghost Wall urges us to wonder how far we have come from the 'primitive minds' of our ancestors. Teenage Silvie is living in a remote Northumberland camp as an exercise in experimental archaeology. Her father is an abusive man, obsessed with recreating the discomfort, brutality and harshness of Iron Age life. Behind and ahead of Silvie's narrative is the story of a bog girl, a sacrifice, a woman killed by those closest to her, and as the hot summer builds to a terrifying climax, Silvie and the Bog girl are in ever more terrifying proximity.
