Paranoid Android

Late last night the outside light came on which I ignored on account of the various animals that cross the path.
After the walk this afternoon I sensed there was something different about the bricks. Close inspection seemed to suggest that some were missing from two of the palettes. How do I know this? Well I pruned the rose the other day and I’m pretty sure the brick was level, now there’s a big hole in t’middle!
But who would go to such trouble to steal 12 bricks… I dunno, but not taking any chances.
Challenge on, Houdini!
Lordy, this renovation is messing with my brain!
