Queen Victoria has a problem: there's a thief at work in Buckingham Palace. The Agency - the secret all-female detective unit - assigns quick-witted Mary Quinn to the case. Posing as a palace maid and fending off the attentions of the Prince of Wales are challenging enough, but when the prince witnesses a murder, Mary's case becomes anything but petty.

Okay, this is going to be short because really there are only a few things I want to say about this novel.

1. I loved it. Really, really loved it.
Mary confronts the skeletons in her closet . The book takes a somber look at the people who sire us and how their mortality and morality affect us. This gives Mary new depths and she evolves much more as a character.
2. The kisses are smoking hot. My toes curled multiple times. It’s quite a feat since I wasn’t even the one being kissed.

This is a rare event for me but I have accidentally started a series in the middle and now have to go back and read from the start! This turned out to be a really good book.
It is set in Victorian London, in Buckingham Palace no less, and it follows the adventures of a young lady who is acting as a kind of private detective. The story is good, the romantic interest is very entertaining and, although I am absolutely certain the author has taken great liberties with the behaviour of Queen Victoria,

I have, honestly, never come across a couple in a book more adorable and perfect together than Mary and James.



Y.S. Lee, THANK YOU, for giving us these two, especially James!



P.S - Queen Victoria is SUCH a badass in this book! :D

This book was absolutely wonderful! There was sooo much you didn't expect. Leave it up to Y.S. Lee to make it a suspenceful yet funny Victorian novel. She put it the right amount of detail in the book. Enough to let you get the main idea of where the characters are and what they are doing, but not so much to bore you to death. It was so good I couldn't put it down until 2:43 am (I could have stayed up longer- but unfortunatly, I had school in a few hours). Something that I enjoy in all of Y.S. L ...more

This is a young adult novel I was granted access to through Netgalley – with thanks to them. It is the third book in a series, but the only problem with that is that I want very much to read the first books and don't have them yet. (This also appears to be called The Traitor and the Tunnel - for the original Canadian edition, perhaps?)

Ugh. I kept reading this series because I did like the basic idea of it and hoped it would improve. It did the opposite of that. The very, very opposite of that.

I’m going to lead, though, with what is good about the series. The central idea is fun, if anachronistic: the main character, sentenced to death for theft at the age of 12, is brought instead to a girls’ school founded on the revolutionary principle that women are capable of independent thought, life, and work. In time, she’s introduced

Oh my god!! It is rare that I find a series that sucks me in the way that Y.S. Lee's Agency series has. It is even rarer when every book in a series gets a 5-Star ranking from me, but that is what happened with these historical mysteries.

The Traitor in the Tunnel is by far the best installment of The Agency series; with the character introductions and early foundation cases out of the way, Mary finally (literally) moves onwards and upwards - in the world and as an agent of The Agency - faces her past and hitherto mysterious Chinese heritage and really makes some serious relationship progress with former beau (of sorts) James Easton. Hurrah.

Blergh. This one really didn't work for me. It was just too... much. In other words, nothing about this felt realistic.

-Mary and James' fight at the start felt contrived, and for dramatic purposes only
-The setting felt over the top (Mary is investigating shenanigans at Buckingham Palace of all things). I mean, sure, some of the stuff with Queen Victoria was a bit fun, but also, really over the top
-The whole sub-plot with the Prince of Whales was just ick. She's a sympathetic and attractive maid

When I first started reading the book I was starting to feel a little let down, so I put it down and thought, what was missing? It was only then that I realized that my anticipation for this book had been building up for over a year, so I had envisioned some almighty holy grail-esque shining novel in which I would hear a choir singing whenever I turned a page.

Mary is undercover posing as a maid in Buckingham Palace, trying to find a thief. Her assignment isn't going as well as she'd like and there is tension in the Agency complicating matters further.

To make matters worse, James Easton is back unexpectedly and Mary suspects that (view spoiler) is her long lost father.

My life sucks so much right now

You do not know how much at ease I am when I read Y.S.Lee. For me, The Agency series turned out to be full of humor, family, friendship and James Easton. Even though the first book was slow to build a steady pace, they were so freaking relaxing. Especially after clawing through the endless chapters of Ulysses by James Joyce.

And what I love most about these epic quick-reads is that the romace is never, ever over-the

I think it's been too long since I picked up this series because although I literally inhaled this book since I borrowed it from the library yesterday, I didn't enjoy it as much. First, anything where royalty is involved just bores me; their generosity, their love for their people, ugh it chafes at me and I don't enjoy all the prostrations that it involves. Second, there wasn't much high tension in the story, for me at least. The resolution to the mystery kinda whimpered out at the

A lot is happening for Mary, both personally and professionally, in this latest installment. It opens with Mary on her first assignment as a fully trained Agent, even though the case - petty thefts at the palace - is a bit humdrum after the excitement of previous cases.

But then, while she's at the palace, this go awry for the Prince Bertie, and the case touches on Mary's on past. She also is left in a position of having to decide just how far she'll go to compromise herself to get information

Y’all, historical mysteries are one of my favorite genres. The Agency series by Y.S. Lee definitely delivers – I love these books! The Traitor in the Tunnel is easily the best yet.

Mary Quinn, working for the shadowy female Agency, is undercover at Queen Victoria’s palace as a maid. Some petty thefts have been going on, and Mary is hoping to figure out who is behind them. Then things get complicated. Extremely complicated. The prince witnesses a murder – and the accused murderer just might be som

Whenever a new Agency novel by Y. S. Lee comes out, I always try to resist the temptation to devour it immediately, knowing that I will have to wait a while until the next book. I succeeded in resisting for all of approximately two weeks after I was approved for it on NetGalley. While, in my opinion, THE TRAITOR IN THE TUNNEL didn’t quite live up to how much I loved the first two Agency books, it is still a satisfying return to Lee’s Victorian London.

My biggest frustration with TRAITOR was that

Recommends it for: people who like silly and stupid romances based solely on passion and physical attraction

Ugh.

Writing is fine. Story is okay. Nothing spectacular.

What annoys me to no end is Mary and James.

Their relationship appears to be all about the physical. They argue and bicker and then kiss passionately and get interrupted before they can do much more.

No meaningful conversations. Or, at the very least, not very many where they aren't yelling at each other. No signs that they really care for one another. It's all about how hot Mary gets underneath the petticoats whenever James is around and Ja

This installment of YS Lee's excellent historical romance-mysteries is, in my opinion not quite as tightly plotted as the last two, but I still thoroughly enjoyed it. If I could, it would get 3.5 stars. Mary is, as always, intelligent, courageous and impulsive. Her thoughts always take more of the center stage than the actual mystery, and in this one, the mysteries are numerous and a bit confusing. They don't end up being related, which was disappointing. And as for James...well, at the beginnin ...more

This is very likely the best of The Agency series so far. Certainly better than the second, which wasn't quite so good as the first, though it's a bit harder to remember that one, as it's been a good year or more since I read it (but I do have some vague recollections of a mystery gone horribly awry). I enjoyed the writing, the story was excellent, and I have a notion that the setting was perhaps a bit better done the others. Also, the addition of Mary's father didn't go amuck.

Okay, this review will be short but let me just some this book up first in three words: fun, addicting, and fabulous.

I absolutely loved the new setting in this one. We went from the absolute lows of Victorian society (the poor and the hardworking who live in shoddy housing and unhygienic places) to the utmost of highs (the ruling royalty). It was so fun seeing how she portrayed everyone from the well-meaning, sharp, but also caring queen to the ineffective, cowardly, and lazy ponce of a prince.

This series continues to be entertaining with well-developed characters and excellent plots. The mystery in this one, the thefts from the palace and the lurking about in the tunnels, is somewhat secondary to Mary's personal mysteries and actions. Not that that is bad, it's just that solving the mystery isn't central to the story, although it is the central story.
Without going into much detail, I loved how this one ended. I would have liked Mary to get to know more about her heritage and why thin

So far this is my favorite book in the series. Of course this is the natural thing for most series because the characters and the world setting is mostly done in the first book. So we already have the established characters and just get to focus more on the plot of the story, which is a new mystery for Mary to solve.
This time the characters involved may be closer to Mary than she would have ever thought. It not only develops a story within the Royal court at Buckingham Palace, but one that leads

This book made me laugh out loud, it made me flip pages frantically to find out WHAT WOULD HAPPEN NEXT, it made me sigh soulfully over perfect romantic scenes, it made me cry, it was-- in short-- a Mary Quinn book. The mystery here is a little less tightly-plotted than the others have been, as the two disparate threads Mary is investigating never coalesce into a larger, joined problem and the payoff in each-- since neither has been the specific focus-- is therefore lessened. But Mary's emotional ...more

I loved this book! Mary finally confronts the ghosts of her past...and she seems to be the better for it. She also has to make some major decisions about where her life is going n this book, and I really hope that she sticks with what she chose. James is so confusing. I mean in the first part of the book, I really hated him for what he did to Mary. But by the end, I was totally back on his side again. The mystery, as usual with Y.S. Lee books was great. I never suspected who was stealing the tri ...more

Nice to see Mary as a full-fledged agent. Glad she was able to see her father for one last time. Also glad to see James again. Wonder if Mary will stay with Anne or go to work with Felicity. Finally, glad that Mary and James confessed their feelings for each other. Can't wait to read Rivals in the City!!!
