I'm back...

 ...and I went for a walk to look at the stars (which are fabulous BTW, it being clear and very very cold) Took this arty snap of the 7.30 train passing some fig trees.

Then I fired off a shot at my side to see what the camera could do at night and lo! This spookiness appeared, left hand corner. There was nothing visible. Snapped some more but no other appearances - guess I frightened it away.  Probably. Blow up below.
