The sixth book in the Joe O'Loughlin series, the inspiration behind major ITV drama The Suspect.

My name is Piper Hadley and I went missing on the last Saturday of the summer holidays three years ago.

When Piper and her friend Tash disappeared, there was a huge police search, but they were never found. Abducted, hidden, and abused, Tash has reached breaking point. She escapes her captor, promising to come back for Piper.

The case is closed. But clinical psychologist Joe O'Loughlin and his stalwart companion, ex-cop Vincent Ruiz, haven't given up. They uncover a chilling link to the missing girls and force the police to re-open the case. But they are racing against time to save Piper from an abductor with an evil, calculating and twisted mind.

Although the Joe O'Loughlin books can be read in any order, Say You're Sorry is the sixth in the series after The Wreckage. The next in the series is Watching You.
