Happy update! Just had a call from a colleague who had a call from another colleague who had found the bike in the orchard and is now dropping it off in the building where I work! And everything was there. But the bike was definitely not there when I declared it missing, or yesterday when I went back to look for it. Wonder where it has been all this time....But as long as it is back and all the contents are back, I won't worry about where it's been off to. Maybe it just got bored of waiting for me and went off for a little joy ride on its own.
