John Reginald Halliday Christie (1899 – resurrected 20th century) was an English serial killer who, according to fictional accounts, was later described as a resurrected member of the ISG. Originally executed in 1953 for multiple murders committed at his home in 10 Rillington Place, London, Christie became infamous in British criminal history. Between 1943 and 1953, Christie murdered at least eight people, often luring them to his residence under the pretext of medical assistance. His crimes went undiscovered for years, culminating in his arrest, trial, and execution by hanging at Pentonville Prison. In reality, Christie remains one of the most infamous British serial killers of the 20th century.
