How to Commit the Perfect MurderModern forensic science should make it impossible to commit murder and get away with it. But how easy would it be to outfox the detectives? With the help of top forensic scientists, and real-life murder investigations, we explore whether it's possible to commit a perfect murder.
The body is the most important piece of evidence in any murder. Pathologist Dr Richard Shepherd reveals the crucial clues that give away the secrets of a suspicious death. Dr Lee Goff can work out a time of death from just a few maggots on a corpse. To really understand the way a human decomposes he relies on experiments - and dead pigs make ideal human models.
And what is the perfect murder weapon? Probably Agatha Christie's favourite - poison. It leaves no marks on the body, and the victim may not even realise what has happened until it's too late. But there still might not be a perfect murder. The world's most notorious poisoner - Harold Shipman - was eventually caught.

Our oceans are turning into plastic ... are we?
Ask a group of people to name an overwhelming global problem, and you’ll hear about climate change, the Middle East, or AIDS. No one, it is guaranteed, will cite the sloppy transport of nurdles as a concern. And yet nurdles, lentil-size pellets of plastic in its rawest form, are especially effective couriers of waste chemicals called persistent organic pollutants, or POPs, which include known carcinogens such as DDT and PCBs.
The United States banned these poisons in the 1970s, but they remain stubbornly at large in the environment, where they latch on to plastic because of its molecular tendency to attract oils.
The word itself—nurdles—sounds cuddly and harmless, like a cartoon character or a pasta for kids, but what it refers to is most certainly not. Absorbing up to a million times the level of POP pollution in their surrounding waters, nurdles become supersaturated poison pills. They’re light enough to blow around like dust, to spill out of shipping containers, and to wash into harbors, storm drains, and creeks. In the ocean, nurdles are easily mistaken for fish eggs by creatures that would very much like to have such a snack. And once inside the body of a bigeye tuna or a king salmon, these tenacious chemicals are headed directly to your dinner table.
