Circumstantially the RTY is just across the road from a famous shop whose owner, just the previous day, had dubbed the Duke of Edinburgh ‘Dracula’, to a jury hearing evidence in the Diana Windsor/ Dodi Fayed inquest.

However, as far as I was able to determine, the only strong light that had the Duke scuttling for the shadows, like the bloodsucker of legend, were the flashguns of over-zealous photographers.
