But when the girl's body is found in the rubble of one of the recently demolished slums around the prestigious new railway station at St Pancras, Lizzie begins to wonder exactly what has been going on. She has re-made the acquaintance of a childhood friend, now Inspector Benjamin Ross, and with his help starts to investigate, risking her life to unearth the truth about the death of a girl whose fate seems interlinked with her own.
