I would also like to thank Nicholas Syfret, QC, who was a mine of information on court procedure and the legal elements of the story.
Thanks also to Professor David Hills for his help with the technical aspects of engineering construction, and to Dr Oli Rahman for answering my medical questions so patiently (if he will forgive the pun). Needless to say, if any errors remain they are down to me, and not to the people who’ve been kind enough to help me.
