With thanks to Gerard Reissmann, who kept me right on the medical bits, to family and friends, for putting up with my regular defeatist moans during the writing, to Georgia Garrett, for her unparalleled guidance, both on and off the page, to Juliet Annan, whose enthusiasm and encouragement is unflagging, to Clare Parkinson, so meticulous and thoughtful, and to David Hastings, for coming up with ‘Hung and Heavy’.
