Q: I am wondering what happened to "Vikings" on the History channel on Thursday nights. The season had just started and "poof" it disappeared.

A: I am not sure how much of the third season of "Vikings" you saw before it went "poof." But the season consisted of 10 episodes, not an unusual number for many series these days. It will be back for a fourth season, and this will be a longer one — 20 episodes total. That said, those 20 will be split into a 10-episode run on Thursdays beginning Feb. 18, then another batch airing later in 2016.

Another 'Turn'

Q: Will AMC's series "Turn" be back in 2016? It's a fabulous story of George Washington's spies during the American Revolution.

A: AMC promises it will be back sometime in 2016.

Tracking 'Law & Order' alums

Q: I watch reruns of "Law & Order" on cable but I don't understand why I never really see some of the actors and actresses after they leave that series. I don't mean Chris Noth; I see him in movies and on TV. But what about Benjamin Bratt, Jesse Martin, Angie Harmon and Jill Hennessy? Or Steven Hill. Is he still with us?

A: The original "Law & Order" went through many cast changes in close to 20 years on the air. And the actors in the series for the most part have found other work, although it may be on shows you don't follow.

Focusing on some of the names you mentioned and their current credits: Jesse L. Martin (Ed Green) is now on the CW's "The Flash." Angie Harmon plays Rizzoli on TNT's "Rizzoli & Isles," which resumes new episodes on Feb. 16. Jill Hennessy has been playing a recurring role on "Madam Secretary," which has resumed this week on CBS. Benjamin Bratt guest-stars from time to time on "Modern Family," and will be on the big screen in "Ride Along 2," which premieres Friday.

Steven Hill, who played Adam Schiff on "Law & Order" for a decade, is still with us at this writing. But, at 93 years old, he is apparently retired from screen work.
