Caela and Mykos have to make this partnership work or lose everything.

Head of a renown PI firm, a crack team at her fingertips, you'd think everything would be easy. Yet, there are strands of poison woven deep into the threads that hold Hughes Investigations together.

Caela can't trust Mykos – but is it because of him? Or because of her?

I don't know, Cay. The way he looks at you? That's not someone who's just in it for the money."
"Oh, I'm sure part of him cares about me. He performs too well in bed to be just dialing it in. But my definition of committed relationship and his seem to be two different things. "

Trust is broken, trouble abounds, and now a serial killer is coming for Caela and those she loves.

"Do you need anything?" Sam asked, voice low.
"Answers," Caela replied. "Why now, after so much time has passed? What was the new trigger? Why not just come for me instead of going after all of my loved ones?"
"Because it fucks with your head. Psychological terror is delicious to these guys," Andy said.

The kills are racking up and Caela is on the list. She got him put away once, can she do it again?
