I see that the latest news from Paris is that the police are saying that an electrical fault is the most likely cause of the fire. Elsewhere I read that the workmen busy in that area claim they switched off the power as they left. To me the police assumption seems a little hasty, perhaps taken an easy conclusion. Little forensic evidence can have been sorted out by this time. Could it not just as easily have been a crafty illegal smoke, discarded and smouldering for a time? What do others think?
