Not all cases are black and white… Police constable Steph is flattered when her neighbour asks for help with strange happenings at the school where he works. She's less than impressed when the problem turns out to be a dodgy printer. Steph's ghost colleagues, Nora and Superintendent Hicks, persuade her there could be more to this case than a rogue ink cartridge. As Steph investigates, she is convinced that someone has something to hide… Can Steph and the team track down the ghost in the machine? Ghost in the Machine is a mystery novelette in the Spirit of the Law series, set in modern Liverpool.
