SOME MURDERS CAN'T BE SOLVED IN JUST ONE LIFETIME.
A mysterious death. A Victorian psychic. A case for Ali Dawson and the Frozen People.
'Warm and engaging characters and a wildly brilliant story wittily told' Ann Cleeves
'A thriller that is full of zest and joy' Nicci French
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.
To distract herself, Ali looks into a present-day case - an apparent suicide of a young man who fell to his death from a high building. She believes the death is linked to a psychic medium called Barry Power, who convinced the boy he could fly. Ali goes to one of Power's shows where he claims to be in contact with Jones.
When Ali notices that evening that her cat, Terry, has gone missing, she decides to go back in time just long enough to prevent Terry from escaping through his open cat flap. A dangerous plan which backfires, and she finds herself once more in Victorian London, where she meets Jones, as well as Power . . .
