DeKay, 49, will appear in an exorcism-themed episode (edgy!) as a deeply religious father whose teenage daughter dies dramatically in the ER. The cops soon suspect his daughter may have been possessed by the devil.
Aside from his starring role as FBI agent Peter Burke on the USA drama, DeKay has guest-starred on Chuck and Law & Order: LA and is known for previous series roles on Tell Me You Love Me and Carnivàle.
White Collar is set to return with new episodes in January. Body of Proof's third season is also expected to premiere in early 2013.
