So, it would seem that it was all an accident after all. Someone left an industrial vacuum cleaner on for two days and a couple of security guards sloped off to a cafe for a kip, missing the beginning of the fire.
You can read about it here. What I wonder, though, is what will happen to the insurance money, if it can be proved that the fire wasn’t deliberately started. I guess they can sue the Italian makers of the vacuum – but it could be argued that leaving in on for an entire weekend wasn’t the best of ideas. The security guards could be rounded up and sent before the beak – but it’s unlikely that they’d have the sort of money that the insurance would be covering.
I hope I’m worrying unnecessarily. I do a lot of that.
