Simply put, this is a wonderful book about compelling and complex women in Montreal at the end of the 19th century. Men in the story are mostly inconsequential, despite some appallingly boorish behaviour. Marie and Sadie are best friends as children, but theirs is a classic love-hate relationship (“Every decent friendship comes with a drop of hatred. But that hatred is like honey in the tea. It makes it addictive”). Marie is spoiled and entitled; Sadie is subversive and dangerous. Ms. O’Neill‘s writing is enchanting with exquisite similes describing disparate worlds: life in a brothel, exploitive factory work (the Squalid Mile). Female relationships are infinitely complex with righteous anger, pettiness and jealousy, and a self-absorbed woman who has no empathy toward other women. Powerful feminist themes abound: the invisibility of marriage, sexual awareness leading to female empowerment. And finally, anticipate a late plot twist and an extraordinary ending. This is O’Neill at her best, a Montreal noir story.
