Billie Piper

Billie Piper (Showtime Entertainment)

The seriocomic, British-made series wrapped up its American run on Showtime with these episodes.

Billie Piper ("Doctor Who") puts the capper - at least for now, since a feature-film spinoff has been rumored - on her portrayal of Belle, a London prostitute with expensive tastes. Cherie Lunghi returns as Belle's former madam, who needs her help here. *** (Not rated: AS, N, P, V)
