The Killing Time. A Mystery

The second mystery following Ali Dawson, the brilliant time-traveling detective, on her newest foray into Victorian LondonDetective Ali Dawson leads a unit that investigates cases so cold her team must travel back in time to solve them. But ever since their technical expert, Jones, got stuck in Victorian London, Ali and her team have been forbidden from time travel. At a loss, Ali dives into a present-day case - an apparent suicide of a young man who fell to his death from a high building.
Ali believes the death is linked to a bad-news psychic medium, Barry Power, who convinced the boy he could fly. Suspicious, Ali attends one of Power's shows, where he claims to be in contact with none other than Jones. Minor trouble closer to home inspires Ali to sneak back in time just long enough to prevent misfortune. Her plan backfires, and she finds herself once again in Victorian London, where she reencounters Jones, as well as the darkly mysterious Cain Templeton, with whom Ali has unfinished business from her previous visit to the nineteenth century .
