I couldn’t sleep so, in the middle of the night, I visited our old neighbours. It was about 1:00am and they were watching television as a wind-down before bedtime. I recognised an episode of The book group on the screen. Our huge drawing room was used for most of the scenes in this series.

On my way back home again, I bumped into some young soldiers on duty guarding the city. One was my Zimbabwean former student PS. He told me that he had just learnt that his father was Idi Amin, and that now he was a celebrity amongst the ranks.
