Christina Bashford wishes to record her thanks to Cyril Ehrlich for reading an early draft of Chapter 1 and for much stimulating discussion.
Tully Potter is indebted to Richard Turner’s comments on the drafts of Chapters 3 and 4.
David Waterman is extremely grateful for the wise and penetrating feedback on the draft of Chapter 5 from Steven Isserlis, Ruth Waterman, Jonathan Del Mar and Sara Fanelli, who are in no way responsible for any of its shortcomings.
