In the early hours of 12 April last year, nine Japanese police officers quietly gathered outside a hotel room in Osaka. Inside and oblivious, 26-year-old Briton Izabel Rose was suffering the effects of a nasty hangover following a night out. Eventually, in need of the communal bathroom, Rose opened the door – and the officers descended.
Days prior, Rose had messaged a friend in the UK asking them to send her the class B drug ketamine. She had left London at the start of the month in the depths of her addiction to the drug, and hoped her travels would be an opportunity for her to get away from her usual environment.
