What's the Name of That Book??? discussion

-> Apologies for my weak English. I am a new reader. I have started to read books now.

I read this particular book a few years back(3-4 years) till exactly half way through the book. I do not remember the title of the book or the author's name.

I vaguely remember the plot.

Plot is like this: There is a guy (name - 'gentleman'?) who is a con artist looking to hire a young girl ( about 17 year old ) who is also a thief living in a poor neighborhood of London (set in 1920s?) to con a rich English family living in the countryside. They have a big estate and they are looking for a maid to take care of the house and the girl. The family consists of a young 17-year-old girl and her old uncle along with a bunch of other maids and servants.
The con assignment is probably to trick this family into giving their wealth and luring that young girl into love by 'Gentleman' and then after the wealth has been transferred the girl would be declared senile or something and sent to an asylum.
Rest of the first part of the book is all about the secret arrangement between the gentleman and the thief girl about how to carry out the con assignment. And the time thief girl and the rich girl spend together taking care of her meanwhile also making sure everything goes as planned and the gentleman lures the rich girl into love and runs away with her eventually to send her to asylum.
At the end of the first half of the book, the thief girl and not the rich girl is sent to the asylum, gentleman tricks the thief girl apparently.

Probably this is a famous book but I can't seem to recall the title of the book.

Let me know if anyone knows the name of the book.
Thanks in advance.

Aanjaneya, please add plot details to the header/ topic title. You can copy and paste from what you've already written. Many people only scan the headers, and we have thousands of book requests.

It’s definitely Fingersmith
