What lies behind the wall at Number 90? Something we should not see, I suspect, judging from the formidable barrier provided by the residents.Perhaps a fortress guarded by savage dogs on long chains, hungry for flesh. Maybe a cortisans court or a den of iniquity where bare breasted nubiles flaunt themselves before the glaring eyes of the lechers who covet them. There may be secrets behind this wall that we should never hear. Whispers of deviance or dalliance. MI5, CIA, ASIO and other acronyms of mystery and intrigue.
Number 90 is telling us: 'Move on. There is nothing here that concerns you.'
