Although the idea is simple enough - use a thief to double cross a lady and win her fortune - there are enough twists and turns throughout the story that kept me guessing right to the end. The novel rarely left my hand in the three days I ripped through it.
I also really appreciate when a writer lets me use my own reasoning without having to spell it all out. There also were enough of the Victorian mainstays to make me very happy: thieves, beggars, proper ladies, dashing villains and ancient, crumbling mansions. The idea of two women falling in love and expressing it openly shone a spotlight on this oppressive social time period when a woman had few rights and even fewer options outside of a traditional marriage.
