This is a very short story (about 4500 words) related to A Charm of Magpies series by KJ Charles. It is not often I give a short story five stars, but I loved the end of this story when Lucien and Stephen are sending notes back and forth to each other (the Victorian era version of texting, I guess). It had me laughing out loud and was related to the thing that happened with the tattoos. Loved that too. I'm working my way through this series and I'm really enjoying it.
