Sorry

Celia Morton, queen of the domestic thriller, can say only one word, and the police think it is a confession. Her surgeon husband lies dead in their Highgate pool, and her laptop holds a chapter describing exactly how he died. Lucy Hurst, a court intermediary still haunted by a barrister who once called her a ventriloquist, is hired to help Celia give evidence without leading her. But every careful question seems to pull her closer to a killer.
