There is a real HMP Edinburgh, situated in the same area of the city as the prison in this novel, but of course this is a work of fiction and the two should not be confused. I am grateful to staff and inmates (present and past) who spoke to me and allowed me to tour the facilities. I have taken a few necessary liberties, but I hope I have also managed to show that prisons are places where compassion and hope can be manifested on all sides, church bells or no church bells.
