Detective Stalky

I figure I see a lot of random stuff on my way to work.  Scary staring dudes, rogue trolleys, giant cat sized lizards, man wearing one shoe, one slipper.  Stuff.  Today I saw a brick pillar that the day before had been standing and today was a pile of rubble on the floor.  It caught my attention because of it's randomness.  And randomness must always be noted.  It even provoked a raised eyebrow on my part as I ambled (no power working with the evil cough of doom) towards work.  The pillar was one of two which marked the entrance to a shared courtyard.  One stood like nothing was amiss, whilst the other lay in a sad heap.  Most peculiar.  Mainly because I wondered how the pillar had come to be like this.  What could topple such a formidable structure.  It didn't look like it had been done on purpose, like someone had planned to remove the pillar.  It was a mess.  A brick mess.  And only one pillar was down.  Not both.  A mystery indeed.  I assume a large vehicle, or something similar, ploughed into the pillar and knocked it over.  But I couldn't imagine a car doing that kind of damage.  The car would surely have had to be going very fast and it seems the pillar would have done more damage to the car.  But then I'm no expert.  Perhaps Rabby would know better.  So, in my Little Stalky opinion, not a car, not a bicycle, not a moped.  Certainly not a land dwelling shark, for they're not known for this kind of destructive behaviour.  So what?  What had knocked over this pillar and left it strewn across some person's courtyard.  Something bigger.  A lorry perhaps?  or a tractor?  What is a tractor doing there?  Why would a tractor be there?  It makes no sense.  A lorry might be passing through, but why would they be near the pillar.  No, to get to the pillar one would have had to have been entering the courtyard, or getting close to the courtyard.  Backing up to the courtyard perhaps.  Backing up to the courtyard...Something big and clumsy that would be backing up to a courtyard.  On a Monday.  Early in the morning.  Before anyone else is up and about.  Early in the morning as the pillar was in tact on Sunday night.  Could it be...the dustbin men!!!  It's the only logical explanation.  It was the dustbin men, in the courtyard, with the candle stick.  Yes, I'll make a detective yet.
