Warr runs a tea and coffee business and also works as a politician; he’s a deputy for the St Helier South district. He doesn’t go on holiday often, but last year he and his wife visited Norway and stayed in a hotel on a lake. The water was murky and dark. There were no shallows. Warr’s wife swam; he dipped in a toe. “I thought, ‘I’m not going in there. I don’t trust myself.’”
