This is a strange and spooky and brilliantly-written tale of a rising folk band in the 70s retreating to an isolated country house to work on their second album. There's drink and drugs and a bit of sex, but these are, as one member describes them, halcyon days. It's the strange doings and secret mysterious obsessions of the doomed lead singer that invokes something strange from the English landscape, that attracts the attention of something or someone best left undisturbed. Told from multiple points of view, this is a wonderful and evocative story, genuinely creepy and disturbing in parts even as it brings to life a long-lost era of music and innocence and possibility.
