Researcher Ruthie Gillespie has undertaken a commission to write an essay on Martin Mear, lead singer and guitarist with Ghost Legion, the biggest, most decadent rock band on the planet, before he disappeared without trace in 1975. Her mission is to separate man from myth - but it's proving difficult, as a series of increasingly disturbing and macabre incidents threatens to derail Ruthie's efforts to uncover the truth about the mysterious rock star. Just what did happen to Martin Mear back in 1975? Is he really set to return from the dead, as the band's die-hard fans, the Legionaries, believe? It's when Ruthie's enquiries lead her to the derelict mansion on the Isle of Wight where Martin wrote the band's breakthrough album that events take a truly terrifying turn .
