The Girl in the Café (HBO, 8-10 p.m.): In this exquisite comic drama by Richard Curtis ("Love Actually"), Bill Nighy stars as a diffident diplomat who is part of the British delegation attending a G-8 summit meeting. Before he leaves for the summit, he falls for a delicate young woman he meets in a cafe. The May-September romance seems impossible - especially since she speaks her mind too readily. But the story is witty and poignant.
Mystery! The Inspector Lynley Mysteries, Series IV (PBS, check local listings): The dashing detective is at odds with Havers, his brilliant working-class sergeant, even as they try to solve the murder of a young couple on holiday. The first of four new episodes.
Empire (ABC, 9-11 p.m.): Julius Caesar is murdered and his young nephew, Octavius, ascends the throne - if he can keep it from his uncle's killers. Rescued from his enemies by the fictional gladiator Tyrannus, Octavius displays a lack of wisdom that nearly costs him his life. Though lavishly made, this miniseries veers into melodrama, with too much carnage - and carnal knowledge - to make it family viewing.
30 Days: Muslim in America (FX, 10 p.m.): Morgan Spurlock, filmmaker of the whistle-blowing documentary "Super Size Me," exposes different aspects of American culture in this six-part series. In the third episode of "30 Days," a Christian spends a month with an American Muslim family. His presuppositions fall away, though he fails to ask some obvious questions about the status of women in the Muslim faith.
