All my friends in Cape Town get press-ganged into reminiscence and fact-checking, for which I am very grateful. As ever, the amazing Birch clan deserve special thanks, as do Abbie Chetwyn and Michael Nel for medical advice, and a host of others for all manner of intriguing contributions.
To live with someone who puts up with the troughs and peaks of being a writer and can then read an early draft and make such well-judged, apposite comments is a tremendous advantage, and my love and thanks go to Gareth Hughes for doing just that.
