   Summary

   You had never expected to come face to face with actual crime when you started to work for rich people. Right up until you were asked to serve at a party and you saw both a wondrous and a horrifying sight: a captive mer.

   Beautiful and deadly and kept in a tank, and despite the danger of the situation, despite the fact that he was clearly very capable of killing you if he felt like it, you couldn't turn your back on him. Doubly so when a mer-child was unexpectedly added to the mix.

   Really, what were you supposed to do but help them escape and hope you'd survive that experience? And why was that dangerous mer watching you like that?
