When a twist of fate puts Trevor in charge of the case, he hastily assembles Scotland Yard’s first forensics team: Davy Mabrey, the first bobby on the scene of the grisliest of the murders, whose working class common sense proves an invaluable asset, Rayley Abrams, a cautious intellectual whose future at the Yard is marginalized due to his Jewish heritage, Tom Bainbridge, a medical student with aristocratic connections and a secret drinking problem, and Emma Kelly, sister of the Ripper’s last victim who has a troubled past and a gift for linguistics. The team finds an unlikely ally in the form of Queen Victoria herself, who takes an unusual level of interest in the Ripper case and secretly funds the unit. But will they stop Jack in time to spare Leanna Bainbridge, the young heiress with whom Trevor has fallen madly and improbably in love?
