I went back to the X-ray Department and found Caroline at her desk. I told her that Fuck Off 45 did not work. ‘Well,’ she sighed, ‘I’d better come and look. Maybe you don’t know how to spell Fuck Off.’ We went downstairs together and returned to the consultation room. ‘Now that I think of it,’ she said. ‘It might have become Fuck Off 47.’ She typed in ‘Fuck Off 47’ and the computer, having checked my credentials – although they were really Mr Johnston’s – to its satisfaction, finally downloaded the menu for the X-ray department at the patient’s hospital.
