Ali Dawson

Ali Dawson and her cold case team investigate crimes so old, they're frozen—or so their inside joke goes. Ali’s work seems like a safe desk job, but what her friends—and even her beloved son—don’t know is that her team has a secret: they can travel back in time to look for evidence. So far, Ali has only made short trips to the recent past, so she’s surprised when she’s asked to investigate a murder in 1850. The killing has been pinned on an aristocratic patron of the arts and antiquities, and member of a sinister group called The Collectors.

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.
