You did it! We figured this one out! It is a truth universally acknowledged (by me for certain) that the Bitchery pretty much knows everything, and really, it's true. Scroll down to see the solution for this HaBO - and many thanks!

This HaBO is from Virginia, who’s stumped on this historical romance:
I need help! I can’t remember this book I’ve read within the last two years. At first I thought it was Duke of Pleasure or Earls Just Want to Have Fun, but I re-read both and the scene I’m remembering is not in either of them.
The scene goes like this: a lowborn woman, possibly a thief or a pickpocket, and an aristocratic man are running though the streets being pursued by either a policeman, a gang of thugs, or another aristocrat. As she runs through a building, she gives a sign to her fellow street thugs and they try to stop whomever is chasing her/them.
I also remember her having a hidey-hole in an attic of a building, and I remember her bringing the guy there at one point and possibly there is either a gun fight or a fire.
It’s driving me nuts; I might be mixing a whole bunch of books together. I read a ton of books at once, so they could have just blended in my memory.
Anything ring familiar?

Possibly Wicked Intentions or one of the other Maiden Lane books by Elizabeth Hoyt?
I read it a few years ago but could it be Jennifer Ashley’s ‘Rules for a Proper Governess’? I remember a chase through a series of alleys and an abandoned alley in that one…
sorry, I meant abandoned building.
This probably isn’t quite right, but the protagonist in Julie Ann Long’s To Love a Thief was a pickpocket.
Maybe Courtney Milan- unraveled? She’s a witness, part of a gang – she wears disguises maybe? and he’s a barrister.. possibly now I am mixing up a few books
@chillyjen I second that! I’m sure it’s Rules for a Proper Governess.
I think chillyjen’s right–Rules for a Proper Governess. Bertie leads the MacBride brother to the alley trap, but he fights his way out. They have to shelter nearby in her “hidey-hole” when he’s hurt later in the book.
I know you said you didn’t think it was Duke of Pleasure, but that sounds exactly like the opening of Duke of Pleasure. Lady helps dude being set upon by a gang, retreats to an attic “hidey-hole” afterwards.
I just love that every guess on this post is going to produce a book I want to read. It’s like my own personal Rec League on top of a HaBo.
Maybe Bec McMaster’s Hexbound? Been a while since I read it but it has a girl thief and an aristocrat getting in trouble in the Seven Dials (her home turf)
Could it possibly be a combo of like two or more books? Because that opening is awful similar to Duke of Pleasure.
Deborah, I would be in the same boat except I already have the first four books mentioned. I can definitely recommend all of them.
Hi y’all, I’m so glad you figured it out. It is Rules for a Proper Governess! Thanks so much!
Woot! I finally solved a HABO. I can die happy now 🙂
This sounds like Jennifer Ashley’s book “Rules for a Proper Governess”.
