Queer Fiction similar to KJ Charles Books?

I've been sucked down the gay old England mystery path by none other than KJ Charles. But sadly, each book has a last page and so do hers.

Which is why I'm in dire need for some book recs, similar to her stories f.e. The magpie Lord-Series or Band Sinister.

I just love the setting and the fact that the books cater towards a more mature readership. (Aka it's not just catered towards YA)

For anyone who hasn't read books of her yet:

• usually mlm / gay fiction (not afraid to also get a bit steamy)
• both mystery and romance centered
• old England / probably around, no idea 1850-1900
• usually has a happy end (I'm a sucker for happy endings, my heart will weep for weeks if it's another bury your gays book)

Thanks so much in advance and have a great day!!
