Robert Donston Stephenson is the last Carriage of Justice activity in the Jack the Ripper DLC: Evie delivers a writer who blamed the murders on black magic, and who had admitted himself to the London Hospital, to Scotland Yard for questioning.
Stephenson says he may have identified the Ripper and that someone wants him dead before he reaches the station. Drive him to Scotland Yard while his suspicious neighbours give chase, staying out of sight for full sync.
Abberline credits Evie with saving the suspect and probably some of his constables as well.
Stephenson sent word to Abberline that he may have identified the Ripper, and believes someone wants him dead before he can tell. His neighbours, meanwhile, suspect him of being the killer.
This closes the Carriage of Justice set. Each of the three passengers protests his innocence the whole way, and each thanks Evie at the Yard.
The carriage is slow and the neighbours give chase, so plan a path away from crowds if you want the full sync.
John Pizer
John Pizer is the first Carriage of Justice activity in the Jack the Ripper DLC: Evie drives this real-life suspect, nicknamed 'Leather Apron', to Scotland Yard so Abberline can question him, while people try to stop the carriage.
Seweryn Klosowski
Seweryn Klosowski is the second Carriage of Justice activity in the Jack the Ripper DLC: Evie escorts a Polish barber living in Whitechapel, later known as a poisoner, to Scotland Yard while a mob convinced he is the Ripper chases them.
Autumn of Terror
Autumn of Terror is the second Jack the Ripper memory: Evie Frye arrives at Scotland Yard in October 1888, learns from Inspector Abberline that Jacob is missing, and rides with him to Whitechapel to investigate the first murder scene.
Letters of Intent
Letters of Intent is the fifth Jack the Ripper memory, dated 3 November 1888: Evie gets a lead from Abberline, rescues newspaper owner Arthur Weaversbrook from Rooks near St Paul's, and then frees his kidnapped son from Jack's men at the docks.
