I’d started to glimpse in Harris what I thought of as a second, shadow personality. The dominant side of him enjoyed banter and refused to give anything away other than wind-ups. That Harris liked – loved – lording it over me. Yet there was another one as well, this one cooler – no, colder. This one practised no sort of friendliness, superficial or otherwise. To be totally honest, he scared me a little. But he did give direct answers. Responses so straight up, so literal, that they seemed almost autistic in character. At first I thought it was just another wind-up strategy, but the flashes of that shadow self were so rare and unpredictable, I began to wonder … I realised that I’d need to watch him all the more carefully.
