I had a day out with Belle in London.

First she took me to the museum café where she treated me to a raspberry and ice cream fruit sundae. I ate it seated next to a Dane who told me that he was hoping to meet some top UK government officials to discuss agricultural policy. When a big party of men in suits arrived to take the big table next to us, we knew exactly who they were.

Meanwhile Belle had disappeared into the toilets with a stranger. When the pair of them returned I could not tell which of the two was Belle. Was this a mystery twin? No, here was a neighbour who specialised in Belle impersonations.

On our way home in a black cab I allowed Belle’s three month old daughter to sleep across my chest.
