South African actress Musetta Vander, who recently appeared in an episode of “Criminal Minds: Beyond Borders,” is guest-starring in an episode in Season 7. Vander announced the news on her official Facebook account and shared several photos of picturesque Oahu in Hawaii where the series is shot. Also appearing in the same episode as Vander is “Barney Miller” actor Max Gail.

Both stars will appear in Season 7, episode 15, according to SpoilerTV. Details about their respective roles are currently unavailable.

“Hawaii Five-O” is currently on a short break and will return with episode 10, titled Ka Luhi,” on Friday, Dec. 9.
