Is it possible to use a knowledge of forensic science, not to catch a killer, but to commit a perfect murder? Modern 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.
