They're baaaaaack -- all the Granthams and Crawleys, that feisty dowager countess, cuddly old Carson, devilish Thomas . . . and more, as a host of new characters arrive both upstairs and downstairs at "Downton Abbey." The season four premiere airs Sunday night at 9 on WNET/13.

Among the newbies: suitors for Lady Mary -- and "they're all really handsome," says actress Michelle Dockery, in a PBS online video.

The Internet is a precarious place for fans, as the season just concluded Christmas Day in Britain, and there are scads of spoilers lurking online. So here's a spoiler-free glimpse at the new folks you'll love -- and love to hate.
