An ill wind.

There was a black cloud hanging over the school all yesterday afternoon and it wasn't just the headmaster's bad mood. I believe it was a cloud of particles from Hemel Hempstead - thankfully it didn't rain. Mr HC reckoned he heard the explosion on Sunday morning, though I didn't hear anything. I wondered, on hearing that the police are saying the catastrophe was an accident, whether the government would tell us if it was in fact not an accident.
