Hester Monk's voluntary work in Coldbath Square is increasingly demanding. Every night she tends to a stream of women of the streets who have been injured or become ill as a result of their trade. But the injuries are becoming more serious, and now a body has been discovered in one of the area's brothels. The dead man is none other than the wealthy and respectable Nolan Baltimore, head of Baltimore and Sons, a successful railway company. With calls for the police to clean up the streets, Hester decides she must intervene to protect these women who stand to lose everything. Meanwhile her husband, William Monk, has been approached by Katrina Harcus, who suspects that the company her fiance works for may be guilty of fraud. That company is Baltimore and Sons. As Monk endeavours to prevent a serious crime, possibly even a tragedy, taking place, he faces some staggering revelations. And with the link between the two cases becoming ever clearer, Monk finds that the time has come to confront his own demons - even if it means losing all that he now holds dear...
