- Author Allusion:
- At one point Strike buys a magazine to get more information on Charlotte's upcoming marriage and passes two other magazines with cover photos of Emma Watson (whose Star-Making Role was Hermione Granger) and Rihanna (whose song Umbrella was the unofficial Leitmotif of Krystal Weedon's rowing team.)
- Fancourt makes a derisive remark on how the only good female writers are those who are childless. The author, of course, has three children and her works are among the best-selling books in history.
