Huge thanks go to my brilliant editors, Tilda McDonald and Clare Bowron. To my agent, Jonathan Lloyd. To Shauna Bartlett for her great copy-edit, Emma Henderson, the editorial manager, and all the team at Michael Joseph, particularly Maxine Hitchcock, for their support for The Anniversary.
I would also like to thank Julia Samuels for her moving and important book, Grief Works, Penguin Life, 2017.
