This Thing of Darkness cover

It was supposed to be a simple investigation of a serial killer... until the mind of the killer was made known. Mulder struggles against truths and lies in the mind of a murderer, while Scully fights against shadows and conspiracies for the sanity of her partner.

Content Warning: Profiler!Mulder is violent towards Scully a number of times in this story.

Tara writes beautifully, so at least while she's putting you through an emotional wringer you can appreciate that she's doing it with such vivid imagery.  😉  This is one for the angst addicts. Be prepared to hurt for a while.
