Women rich and poor come to her, desperate and in dire need of help – and discretion. Dolly Merishaw is a midwife and an abortionist in Victorian Toronto, but although she keeps quiet about her clients' condition, her contempt for them and her greed leaves every one of them resentful and angry.

Now, Murdoch isn't sure if he's hunting one murderer – or two.
