it's a mystery

9.05am; I open the back gate and there's a ladder leaning against the wall in our car-parking space.  Never seen it before.  It certainly wasn't there last night. I go back inside, get my phone and take a picture of it.  

The street is quiet - a few cars parked, but no-one around.  It's also a cul-de-sac - only one way in and out. Ours is the last house.

9.20am; I go back outside and the ladder is gone. 

9.45am; I look out of our upstairs window.  There's a man wandering about, clearly looking for something.  He takes his time, nosing around the car-park, peering at people's houses and eventually stops in the middle of the street.  He shrugs, has a last look around, then turns and walks back down the street onto the main road.

As Toyah Willcox once said - it's a mystery.
