The actress will appear in the ninth episode of the third season.
However, things aren't going to be perfect in the White Collar world by the time she comes around.
[Spoiler alert!] Things are headed for trouble between con man Neal Caffrey, played by Matthew Bomer, and new love interest Sara Ellis, played by Hilarie Burton, midway through the upcoming third season, which launches next Tuesday at 9 p.m.
Eliza Dushku is playing a rather sexy role, and is working for Matthew Keller (Ross McCall), and ends up having a fling with Neal, who just broke up with Sara.
The show also might have plans to bring back Eliza Dushku's character for the fourth season.
