So there I was digging away, happy in my own little world when the spade snagged on a stone. As is my habit and as I was taught by my gardening neighbours many years ago, I went to pick up the stone to throw it into the hedge. One day in years to come I will be found behind a 20 foot wall of flung stones but my borders will be fine stone-free tilth; however I digress. As I stooped to pick up the stone I realised it was not what I thought. I picked it up and at first thought it was a large bolt as there are many in the garden. After a bit of a rub to remove the soil I realised two things. Firstly that it did not contain a genie and secondly that it was a window catch.
