He and Michael, who had both been students at Oxford, had met through the aikido club. As it had turned out, both of them were in Mansfield College studying Politics, Philosophy and Economics, Edwin a year ahead of Michael. On several occasions, Michael had brought him to his family home in London, claiming he needed to be exposed to the reality of how others lived. In London, Michael had taken him to the homeless charity where he had volunteered when in sixth form, and to his local aikido club, where he heard about their programmes to encourage teenagers into sport and away from knife crime. And Kara had tagged along, listening attentively to Michael’s opinions, smiling when Edwin and Michael disagreed over some issue. She had visited Michael in Oxford and had gone to parties with them, the only person to ever persuade Michael out onto the dance floor. Kara had idolised Michael and their parents had worshipped him. Edwin used to tease him over it, Michael always shrugging it off until one evening during his second year in Oxford, when they were both at a house party. Michael was drunk and fell and spilt a drink all over someone’s laptop. The owner screamed at Michael. Michael just stood there staring at the girl as she ranted at him, not reacting, looking as though nothing was registering with him. And then he disappeared out of the house. Edwin followed him, unsettled by the blankness in Michael’s expression.
