This was a fun read with great period detail. Lane is a great heroine with minimal TSTL moments. Yes, there were a few, which was frustrating, esp when she acknowledges that unlike dumb females in movies, she knows better than to not stay put when told (sly wink), then goes prancing off and gets caught (repeatedly). But I suppose it's not much of a story if the heroine is always obedient and careful.
The setting of the story was vivid, and 1930s New York felt like its own character in this novel. I love all the descriptions of Lane's clothes, the food she ate, and places she went. I learned some history too, which was presented as a natural part of the narrative in a non-pedantic fashion. The description of the characters were vivid and full, and I felt like I got to know some of them (Lane, Fio, Aunt Evelyn, Mr. Kirkland) so well after just a short time. They were really well-drawn, and I was engaged from the start. (Fio is the greatest)
A couple nits: I don't live in NY, but it did seem to me that 1930s NYC must only consist of about 10 city blocks and about 500 people, for all the coincidences that keep cropping up. Where does everything take place? How does Fio arrive on the scene of every crime within minutes? How does everyone keep running into each other, fortuitously or otherwise? For that matter, why is it that Finn (whose mystery, I thought, was not very mysterious at all) has zero operational security? For someone whose existence Lane shouldn't even know about, lest it endanger her, he sure is casual about hanging around, taking her out in public places, and opening them up to situations in which they could be easily seen (though this seems to be the only time that people actually *don't* run into each other on the street). Don't get me wrong - I liked Finn and getting to see their relationship develop. It just seemed like he could have been a lot more wise about it. Just sayin'. The mystery was fun - one plot twist made me shout, "WHAT?!" and another, "I knew it!!" That's the mark of a good mystery to me. ;)
I'm very much looking forward to reading the next installment in this series. Thanks to the publisher for providing an ARC via netgalley in exchange for my honest review.
