I have some vivid memories of that journey. We travelled first class so the food and accommodation were good, and we enjoyed important events like ice cream served on deck at eleven every morning with, occasionally, second helpings. I remember the magnificently decorated rickshaws in Durban pulled by Zulus in feathered finery, and the huge shark which swam beside the ship in one of the east coast ports. I recall catching a small black fish off the stern of the ship, this achieved by lowering a tin on a long piece of string - though I can't recall what I provided in the way of bait, nor how I obtained the tin and the string. I remember going ashore at Gran Canaria and being captivated by the brilliant yellow canaries for sale in cages. I desperately wanted one but my parents vetoed the idea.
As we approached the Bay of Biscay, the ice cream was replaced with bovril. The weather deteriorated, we had to wear thicker clothing, though however thick it was it didn't seem to keep me warm. And when we docked at Southampton I remember being amazed to see white men doing labouring jobs like mending the roads.
It wasn't a good leave. My father was ill with suspected TB, so we had to spend an extra two months in a bitterly cold winter. Fortunately, we had a pleasant flat overlooking the Thames: I recall having to cross Putney Bridge to reach the small private school we attended.
