The A-Z Killer

Rachel Nickell was brutally stabbed to death on Wimbledon Common in 1992, in a case that would become one of Britain\'s most notorious investigations. After an extensive manhunt, police believe they\'ve found her killer, but after a year in custody, the trial collapses, revealing they have the wrong man. As the investigation deepens, detectives uncover links to other violent attacks, pointing to a far more dangerous offender-the so-called A-Z Killer. Is a psychopath still at large, and how long before he strikes again?
