G, after 24 hours you really should report him as missing to the police.
Can Julie not pull in some favours with her guv'nors and put out an all out search for him?
Maybe they could pull Interpol in if indeed he did not return safely from Austria.
I did ask Stu where he was at the weekend but he did'nt know either so he has not emigrated to south Wales.
We are thinking of you in your time of need.
Here's hoping for a happy ending.
