Three women. Three dates. One missing man.

8.52 a.m. Siobhan's been looking forward to her breakfast date with Joseph. She was surprised when he suggested it - she normally sees him late at night in her hotel room. Breakfast with Joseph on Valentine's Day surely means something... so where is he?

2.43 p.m. Miranda's hoping that a Valentine's Day lunch with Carter will be the perfect way to celebrate her new job. It's a fresh start and a sign that her grown-up life is finally falling into place: she's been dating Carter for five months now and things are getting serious. But why hasn't he shown up?

6.30 p.m. Joseph Carter agreed to be Jane's fake boyfriend at a colleague's engagement party. They've not known each other long but their friendship is fast becoming the brightest part of her new life in Winchester. Joseph promised to save Jane tonight. But he's not here...

Meet Joseph Carter. That is, if you can find him.
