Elise Ward is in a cell for murder, and she is safer than she has been in a month.
While she is locked up, the killer keeps working. A surgeon is buried upright in an Atlantis dune. A colleague is found overdosed. A cellmate wakes at 3 a.m. and swears a cleaner was standing at the door. The police call it an accomplice. Elise calls it impossible, until her sleep-lab partner Deon pulls the noise floor off her recordings and finds a whisper two seconds before every word she says asleep, followed by two soft knocks on wood.
Someone has been in her bedroom every murder night, feeding her the lines.
Then her daughter Maisie, asleep, says something no child should "Somebody knocks two times so you don't wake up."
The trail runs through a cleaning contractor with keys to every building, a borrowed name, and a trial nobody remembers. It ends where it began, in the dead Harbour sleep centre at 02:30, with Maisie asleep in Room 705 and one rule Elise must not do not wake her.
The explosive conclusion to the Harbour case.
