Part three of a series on the history of Jack the Ripper, a renowned serial killer investigated during the Whitechapel murders of East London in 1888.

Part 3 - The night of the double murders of Catherine Eddowes and Elizabeth Stride. Evidence and eyewitness testimony really heats up as the investigation stalls but the murders become more and more grisly. Jack is likely to have been seen by an eyewitness and later, sends a letter to the police, writing Dear Boss... & famously signing his name for the first time.
