Burn the house down

Some tenants, living in a brand new and very expensive flat had been working abroad for a few weeks. When I arrived on their moving out day they had packed up and left but I discovered that for possibly the whole tenancy they had pushed one of the leather settees up against an electric wall heater, the back of the sofa was blackened and brittle and not long from bursting into flames I would imagine. I also discovered that the lounge door had been pressed against a heater and this too was charred and black. A few more days and the whole place could have gone up in flames - which would have damaged several luxury properties (and probably occupants) in the same block of flats. I think this development could be cursed there have been several distinctly dangerous incidents - more of which later!
