London dust

A young woman, Natalie Meadows, jumps from Blackfriars Bridge, escaping from the horror she has just witnessed.

But she is rescued and feels duty-bound to find out who murdered her best friend, the music hall star Nellie Warwick, and why.

Natalie reinvents herself as Flora Thorne and finds a position as housemaid to the Reverend Wallace and his daughter.

From the sanctuary of their home, she is able to investigate the circumstances of Nellie's murder.

What she uncovers is a conspiracy of silence and corruption, and of unscrupulous men preying on women like herself and Nellie.

Her attempts to unmask the killer and bring him to justice exact a heavy price on Natalie.
