In Europe today, it is what goes unacknowledged and un-commemorated that reveals the trouble we are in. Recently in Marseille, two women, aged 20 and 21, were walking past the Saint-Charles train station. The women — named as Mauranne and Laura — were cousins, one a medical student, and the other a trainee nurse. A man stabbed both of them to death, while shouting «Allahu Akbar» before each assault.
