Castle, back in time and the moon.

1. In St James' Park, looking back up to Horse Guards Parade and the Ministry of Defence behind. It looks like a fairy tale castle. I think that the MoD has King Arthur and his knights sleeping in one of the towers, in case of national need.

2. To come off a hot, bright shopping street in London and walk down a narrow lane that looks as if it hasn't change since 1780.

3. The moon (white silver and shaped like an egg) has been peering round clouds and through the window of the train all the way home.
