In the third installment of the Agency series, we find Mary Quinn already deep in another adventure and in a new disguise. Promoted to the role of a full agent in the Agency, she's acting as a parlor maid in Queen Victoria's palace after it's been discovered that a number of trinkets has gone missing. 
 I really enjoyed the deeper insight into the past life of Mary and a closer look at the mysteries surrounding her father. I found it really helped complete her character. As a very strong and independent female character, it was great being able to see where she got all her strength from, especially being a young woman in Victorian England, orphaned at a young age, and being half-Asian in a time of great tension. 
 Of course the book wouldn't be as good without the appearance of the infuriating but lovable James Easton. He's probably one of my favourite things about the series. He's just so charming! 
 Also, thinking this was the final book in the series I was pleasantly surprised to find out that there will be a 4th one! It's working title is The Rivals in the City and I can't wait!
