Awww! A happy ending. Just got a call on my mobile. She said she was Cassie or something similar, I explained that the bike had been stolen from me. And she said she'd unlock it and I could just go pick it up! Someone gave it to her when her bike was stolen from outside her work a while back. She said she was really pleased we'd been reunited, and that it was a lovely bike :-) So I guess I'll be popping over there tomorrow lunchtime or something. Too tired to go tonight, and I have a meeting first thing tomorrow.
