As I was sitting perusing the site this morning (hooray for holidays!) I suddenly heard our back gate close, which is quite a distinctive sound. Trouble is, it's double-bolted and there is trellis over the top to discourage casual climbers. I did watch the window for a few moments to see if anyone or anything appeared, but nothing. I even went out and checked that the bolts were still shot, which they were. Most peculiar. I'd heard some scraping on that fence a few minutes earlier, which I assumed to be some kind of wildlife - we're overrun with squirrels at the moment - or even the neighbours faffing around in the tiny gap between the fence and their house, but the click of the gate closing is not something easily replicated.
