Leeds, England. October, 1891. An unclaimed parcel at the Central Post Office is discovered to contain the decomposing body of a baby boy. It's a gruesome case for DI Tom Harper. Then a fire during the night destroys half the railway station. The next day a woman's body is found in the rubble. But Catherine Carr didn't die in the blaze: she'd been stabbed to death and Harper has to find her killer. The estranged wife of a wealthy industrialist, Catherine had been involved with the Leeds Suffragist Society, demanding votes for women, the same organization for which Harper's wife Annabelle has just become a speaker. Were Catherine's politics the cause of her death? Or is the husband she abandoned behind it? But when her brother escapes from the asylum and steals a shotgun, Harper has to race to find the answers.
