Ok, so, a not very hypothetical situation:
Friend is very seriously ill (has only been given a few more months to live). Is in relative denial about this despite all treatment having failed.
Has been getting on really badly with husband.
Has now disappeared- been gone since Friday evening. Her phone has been traced to a town on the south coast but she is not answering it. Husband beside himself.
She is normally a very feisty woman but things have been going quite badly in her household recently. She is not happy there.
What does this sound like to you? A woman who just wants a few days away by herself, or something more sinister? Would she want to be found? Is it worth starting a MN search campaign in the town in question?
What would you do?
