The definitive and explosive account of a harrowing murder case that has shocked Britain Peter Tobin was already serving a life sentence for murder when he was charged with the murder of two young women - Vicky Hamilton and Dina McNichol, in November 2007. Both girls went missing in 1991. Their bodies were discovered by police in 50 Irvine Drive, Margate - where Tobin once lived. In their new true crime investigation, Paul Harrison and Professor David Wilson examine this shocking case, including full details of Tobin's trial. But perhaps even more importantly, they look into other similar cases around the country. With developments in DNA testing, the police are coming closer and closer to solving a range of terrible and high profile murders. There have been at least five major arrests in recent months, with further arrests sure to follow. Harrison and Wilson investigate these cases, and ask how new DNA tests will change police investigations. But they also ask whether this will be enough to stop murderers in the future, and whether there are larger forces at work in society that need to be addressed before we can stop people from killing again and again.
