Robert Maudsley, the serial killer that inspired the creation of Hannibal Lecter, is one of the most interesting and curiosity-inspiring murderers still in prison. He will be in isolation for the rest of his life. He is such a danger to others and himself that he lives in a specially designed cell that bars him from contact and the outside world. People who are aware of his existence are on the fence about whether he should be considered a serial killer, a multiple murderer, or even a vigilante. Robert Maudsley has been deemed the most dangerous prisoner in Britain. Even though he is a serial killer, he had only murdered one person outside of prison. His remaining victims were claimed while he was incarcerated and became a huge part of the necessity for him to have a special cell built.
