Lady Cassandra Greenwich and her best friend Lady Emilia Lockwood has everything young women in Victorian England could want. Wealth, beauty and the pick of all the bachelors fashionable London society has to offer. But the fiery women are uninspired to find love among the insipid gentlemen who prowl the drawing rooms of the elite ton. Ladies of leisure by day and masked avengers by night, Cassie and Em find themselves investigating a string of suspicious murders in London. Unable to make much headway on their own, the pair stumbles across four strangers who will change their lives forever. Is the Marquis and Marchioness of Konstantin what they pretend to be – just another well-to-do, striking couple? And what of their two incredibly attractive male companions? Who are they and how are they related to the murders? Will Cassie and Em solve the mystery of the murders and perhaps find true love at the same time, or have the two friends finally bitten off more than they can possibly chew?
