It can't be just after dawn, not everywhere anyway. Shadows in central
London (e.g. Nelson's Column) indicate that it's late morning, roughly
around 11:00. There's an event of some sort in Trafalgar Square. From
the works going on in Devonshire Road, Chiswick, I would say it was
around January or February this year. Colin says it must be a Sunday
morning. Between us on this NG, we ought to be able to pin it down to a
date.
