Editorial Reviews


Victorian England comes alive again with Y.S Lee’s third novel in THE AGENCY series. Lee has a terrific knack of combining intrigue, romance, and mystery with the strong female character, Mary Quinn... Girls of all ages will enjoy the fast pace, the twisting plot, and most of all, the romance that awaits them.

Lee, as ever, paints an evocative picture of London life... Mary makes for a bold heroine (sometimes too bold for her own good), and her fans will want to find out how it all ends.

About the Author

Y. S. Lee was born in Singapore but brought up in Canada. She has also lived briefly in the United Kingdom. An academic with a PhD in Victorian literature and culture, she wrote Masculinity and the English Working Class in Victorian Autobiography and Fiction. She lives in Ontario, Canada.

Reason for Reading: Next in the series.

An excellent finale to "The Agency" trilogy. Mary Quinn's character has grown from a rag-tag orphan thief to a young woman now ready to live independently in a world where men usually have the upperhand. This was a fun case all-round, which has Mary playing parlour maid inside Buckingham Palace to rout out who has been stealing odd pieces of ornamentation, all to no avail. However when she thinks the case is not going to go any further, the details of the murder of a friend of the Prince of Wales is being kept all "hush-hush" and the Prince has been banished to seclusion. Now here is a case Mary can sink her teeth into! But how is it related to the thefts and why does Mary think she may have finally found her father.

Many issues that have been brought up previously in this series are put together and solved to the reader's satisfaction. By the end of the book one quite forgets they are reading a YA novel, and feels more like they are in a Gothic Romance. Mary is a feisty woman and her paramour James seems to like that in a woman because nothing she says, does, or reveals shocks him. I thoroughly enjoyed this tale.

Now, we've been told this is the end of a trilogy and the book does have a finite ending in certain respects, while in others there is still plenty of openings for a new trilogy or series to continue from here; perhaps more of an adult read than YA. Though either way I'd be happy. Towards the end of the book, James and Mary had a decidedly Tommy and Tuppence air about them and I'd love to see them together in their own series aimed at adults.

ETA: Well after a little looking around it seems this is no longer being tooted as the last book in the series and Lee is indeed currently writing a fourth book about Mary Quinn! Good news to my ears! We'll see if she uses this opportunity to make any changes to the series or just continues on with it. I'm happy either way.

4.0 out of 5 stars Amazing! March 10, 2012
The Agency 3: The Traitor in the Tunnel by Y. S. Lee continues the story of Mary Quinn. This time she has to pose as a parlor maid in the Queen Victoria's household to solve a case of petty thief. However, while she's there, the Prince witnesses a murder of one of his friends. To make matters worse, Mary finds out the murderer has the same name as her father.

I really love this series and have enjoyed each and every one so far, so I couldn't wait to get this book and read it. This book is no exception. Just when you think you got things figured out, a new twists comes into play.

It was nice to read more about Mary in this book as well and about her father. It went into more detail about what happened, or what she knew about her father, and her reaction to the fact that her father might still be alive.

Also, James comes back into this book, much to the surprise of Mary. In the last book, Mary and James didn't leave things as pleasant and she's afraid of that repeating itself. However, James wants nothing more than to bury that in the past and start over. Which is great because I'm really liking the two of these together. And if you're like me and like them, let's just say, you'll LOVE what happens! I don't want to spoil it too much, but towards the end of the book, there some really good moments and well, I'm very happy. :)

Because there is a mystery involving the tunnels below the Palace, most of what happens, especially later on in the novel, takes place in the tunnels or the sewers. While that's great as far as the mystery goes, it can get a little boring. James and Mary have great interaction during this process, but sometimes I felt myself wanting to skim.

4.0 out of 5 stars Lovable Characters May 27, 2012
After reading all three books in this series, I have got to say that my favorite thing about them is the characters. Mary and James are complex, funny, and an absolute delight to read about! Mary and James also have great "chemistry" and you will often find yourself laughing out loud at their witty banter. While the actual mystery they are supposed to be solving tends to take a backseat to their relationship (to the point that you almost forget you are reading a mystery novel), the dilemma is always solved in a fast-paced action sequence that leaves the reader satisfied. Plus, James and Mary are so darn lovable that you are always left wanting more of them (fourth book please?!) and don't mind the plot straying from the investigation.

What a wonderful storyteller! I absolutely loved the way Ms Lee developed the characters in these three books. The portrayal of Queen Victoria was right on the spot, I believe.

Who doesn't like a mystery that not only has a historical setting, but includes romance and drama?! :) Another great Mary Quinn mystery book! This is the third book in the Agency series featuring the smart and strong heroine Mary Quinn as a secret spy in the mid 1800's, set in England.

In The Traitor in the Tunnel, Mary is assigned to work undercover as a maid in Buckingham Palace, where she has to solve what supposedly will be a simple case. However, unexpectedly, her one case becomes three mysteries! In one case, she has to deal once more with the ever so charming Octavius Jones, the very sneaky journalist from book two (I think he has a crush on her. Oh my!). In another case, she has to work with James, who seems, that this time, is determined not to let her get away from him (Oh my, again!). And lastly, she stumbles upon a mystery that might finally make her confront fully her past. She finds out that her long lost/allegedly deceased father might not be dead at all, and instead, is being held as a prisoner in the infamous Tower of London on the charge of murder of an aristocrat!

Wow, what a book! The mysteries found inside this book were quite complex. And even though, I felt that some questions were still left unanswered regarding her family, even when it came to James, after a few comments made about his trip to India, overall, it was a solid mystery book!

*Pg-13 level*

P.S. I was able to read this book thanks to my town's public library.
