THIS WORLD
BBC Two, 9pm

Bad Medicine is a damning exposé of a crime that amounts to mass murder — the manufacture and distribution of fake pharmaceutical drugs sold in unregulated markets in the Third World. These are not just cut-price copies; either they fail to do what it says on the packet, or they are so low- strength that they help to spread drug-resistant strains of disease. The subject is surrounded by a culture of secrecy and denial, while thousands of its victims remain invisible. In this important and courageous programme, the reporter Olenka Frenkiel follows efforts by the head of Nigeria’s Food and Drug Agency to tackle the problem.

STREETS AHEAD
Channel 4, 8pm

I don’t believe it. Having done everything that the property expert Sarah Beeny has been telling me to do for years — I’ve got rid of the rabbit hutches in the hallway, sold my prized collection of manhole covers and painted the dog white — now, it seems, I’ve got to worry about whether or not the house has “kerb appeal”.

Since potential buyers want an area to look safe, tidy and well tended, Beeny encourages folk to get together and increase the value of their homes with a bit of Neighbourhood Watch-come-DIY. My wife thinks this is a brilliant idea and says I should stop sneering and cut the bloody hedge.

KHUBILAI KHAN’S LOST FLEET
Five, 8pm

The greatest naval disaster in history took place in August 1281, when 4,000 ships carrying Khubilai Khan’s Mongol army sank with the loss of 70,000 men off the coast of Japan. This rather protracted documentary (below), describes how a marine archaeologist discovered the remains of the fleet, and explains why the vast fleet sank in such mysterious circumstances.

CSI: CRIME SCENE INVESTIGATION
Five, 9pm/10pm

Quentin Tarantino, who wrote and directed this two-part edition, takes a formulaic series and transforms it into a white- knuckle ride. One of the CSI team is kidnapped, drugged and buried alive in circumstances horribly similar to Uma Thurman’s kidnapping in Tarantino’s recent Kill Bill Vol. 2. A live web link has been set up by the kidnapper between his glass coffin and the CSI headquarters, and the team race against the clock to rescue him. It is the most exciting and stylish edition of CSI ever made.

MY LIFE AS A CHILD
BBC Two, 9.50pm

Whoever came up with this brilliant and obvious idea (obvious once you have thought of it, that is) has struck a seam of pure gold. The programme-makers gave small cameras to children and asked them to record their lives. It turns out that their world has more to do with power, money and designer labels than anything to do with vulnerability or innocence.

Here, for example, is nine-year-old Chelsea talking about the men who stare at her mother, a model.
