Tonight's episode marks the winter season finale of Bones and it looks like there'll be a lot of exciting twists and turns as Joshua Malina (In Plain Sight) and Pej Vahdat guest star in "The Devil in the Details."
As the title suggests, the case this week involves the remains of a man found resembling then devil which is ironically found at a church. Booth and Brennan dig deeper into the allegorizing biblical text that comes with the case and identify the victim as former patient of Dr. Adam Copeland (guest star Malina) at Havenhurst Sanitarium. But as they investigate further, they are confronted with suspects who are hard to characterize as either good or evil.
Meanwhile, Jeffersonian intern Arastoo Vaziri (guest star Vahdat) reveals a secret about his past.
Here's the trailer for tonight's episode just in case you missed the preview released by FOX last week:
