The identity of Jack the Ripper, history's first and most notorious serial killer, has confounded experts for decades. Here, at last, may be the answer to this compelling mystery. A diary found recently in Liverpool is filled with clues that identify its author as James Maybrick, a cotton merchant who died in 1889 of suspected arsenic poisoning. Although Maybrick's wife was accused of his murder, the diary indicates that his poisoning was probably the result of his own arsenic addiction, an addiction that contributed to a secret life in London - as Jack the Ripper.

The diary is the subject of considerable controversy, and a report questioning its authenticity is included here, along with a rebuttal to that report. Follow the detective work that overlays the diary with what is known about James Maybrick and Jack the Ripper and decide: Were they one and the same?

Narrated by British actor Nicholas Ball. Narrative text by Shirley Harrison and Michael Barrett.
