The Thin Blue Line - Septiplier AU [CON]

Mark gets called in to take care of a basic 10-50, which seems easy enough and accepts without hesitation.
Upon hearing more about the situation, he begins to get an off feeling about not the character in question, but rather the couple who called it in. His partner, Wade, has similar thoughts, but the two press forward, unaware of what they're getting themselves into.

This is the continuation of a book by another talented writer @BrieBrittany , so definitely go check them out since their writing is amazing. They wrote chapters 1-12 which I will still publish here so that it will still make sense to readers who have come from the previous book.
The cover, description (apart from this A/N), first chapters and everything will be exactly the same.
