A mystery has occurred. In The Affluent People’s Republic of North London, a rabbi was stabbed on the street multiple times by a knifeman. Rabbi Alter Yaakov Schlesinger was rescued by two builders and a Deliveroo driver and is now in hospital, where hopefully he will recover. Apparently no robbery was attempted. The police, however, have said that this was not a terrorist incident, thus suggesting – by extension – it was also not a hate crime. A crime of love, or indifference, then? Who knows? All a mystery. A familiar mystery.
