No. 1 Ladies Detective Agency No. 1 Ladies Detective Agency

The No. 1 Ladies' Detective Agency
8 pm/ET HBO
Never underestimate a woman's intuition. An ebullient Jill Scott stars as Precious Ramotswe, a woman who opens the titular agency after her father dies. In the breezy, two-hour premiere episode — which was written by Richard Curtis (Bridget Jones, Four Weddings and a Funeral) and the late Anthony Minghella (The English Patient) and directed by Minghella — Precious sets up shop and investigates all sorts of female-centric malfeasance. The postcard-pretty series, based on the best-selling novels by Alexander McCall Smith, was filmed entirely on location in Botswana. A nearly unrecognizable Anika Noni Rose (Dreamgirls) costars as Precious' odd assistant.

Amazing Race 14
8 pm/ET CBS
Plucky flight attendants Christie and Jodi were finally jettisoned last week in India, leaving six teams to continue the race tonight in sweltering Thailand, where things get really wild. The racers experience close encounters with a foot-massaging elephant and a supposedly tranquil tiger. At the pit stop, Margie collapses on the mat due to the region's extreme heat. —Tim Holland

United States of Tara
10 pm/ET Showtime
In this commendable outing, Tara decides to take matters out of her own hands and put them in someone else's by checking herself into a clinic. The resident expert, Dr. Holden (Joel Gretsch), preaches that she must deal with her repressed memories because "you can't get better until you know what happened to you" and that it's time to "break down the walls" between her and her alters. The alters, however, aren't interested in breaking down any walls and block efforts to dredge up the past. —Ray Stackhouse

Masterpiece Classic
9 pm/ET PBS (check local listings)
Newcomer Claire Foy is a delight in this sparkling five-part adaptation of Charles Dickens' Little Dorrit, from the pen of famed screenwriter Andrew Davies (Bleak House, Pride and Prejudice). An oft-overlooked entry in the Dickens pantheon about financial ruin, rebirth and sacrifice in 1820s England, the story opens with young Amy (Foy), whose father (Tom Courtenay) has been in a debtors' prison for a quarter century, going to work for a stern shut-in (Judy Parfitt). —Jeff Gemmill

The Simpsons
8 pm/ET FOX
Homer and Marge are not married! It seems that Reverend Lovejoy's recertification fee was declined by his credit card and everything he has officiated during the last three months is invalid, and that includes — you guessed it — Marge and Homer's second marriage. An elaborate ceremony to renew the Simpsons' vows is planned, but will a kidnapping keep it from happening? —Fred Mitchell
