Ali Dawson

Ali Dawson is a police officer working on crimes so old, the joke goes, that they are not only cold but frozen. What most people don't know is that the team travels back in time to complete their research - a process pioneered by the mysterious Italian physicist, Serafina Pelligrini. So far the team has only ventured a few years back but Ali's boss has a new assignment for her. He wants her to step back to 1850, the heart of the Victorian Age, to clear the name of Cain Templeton, the eccentric great-grandfather of Tory MP Isaac Templeton.

Ali Dawson is a police detective who leads a unit that investigates cases so cold her team must travel to the distant past to solve them. But Ali and the team haven't been allowed to time-travel ever since their technical expert, Jones, got stuck in Victorian London, never to be seen again. To distract herself from meaningless tasks, Ali decides to look into a present-day case - a series of apparent suicides, all young men who fell to their death from high places. She believes the deaths are linked to a psychic medium called Barry Power, who convinced the boys they could fly.
