Beau Bridges, Tim Dekay

Beau Bridges will appear on an upcoming episode of White Collar as Peter's mentor, TVGuide.com has learned exclusively.

Bridges, 69, will play Agent Kramer, a well-decorated federal officer and art expert who instructed Peter (Tim DeKay) when he trained at Quantico. Kramer has been Peter's mentor ever since, and his paternal nature offsets his intimidating presence.
