The forever watch - David Ramirez

The Noah: a city-sized ship, half-way through an eight-hundred-year voyage to another planet. In a world where deeds, and even thoughts, cannot be kept secret, a man is murdered; his body so ruined that his identity must be established from DNA evidence. Within hours, all trace of the crime is swept away, hidden as though it never happened.

Hana Dempsey, a mid-level bureaucrat genetically modified to use the Noah's telepathic internet, begins to investigate. Her search for the truth will uncover the impossible: a serial killer who has been operating on board for a lifetime... if not longer.

And behind the killer lies a conspiracy centuries in the making.
