Abberline, We Presume introduces Sergeant Frederick Abberline, who meets the twins in a Whitechapel alley wearing a dress and bonnet. To earn police cover you kidnap a criminal named Homer Dalton and deliver him alive to Abberline's carriage.
Part 2 of 5 in Sequence 3: A Modern Babylon
Meet Abberline in the alley; he wants gang members brought in quietly, with no corpses left at the station. Find Dalton, grab him and walk him back while keeping guards outside the ring that appears around you. If he breaks free, chase him down and restrain him again. Load him into Abberline's carriage and drive him to the police station.
Walking slowly keeps the detection ring tight; running makes it balloon. Killing Dalton fails the optional objective, so keep your blade sheathed until he is in the carriage. If Dalton breaks free he shouts for help and runs. Catch him before he reaches a crowd, then hold him tight on the walk to the carriage.
Dalton ends up behind bars, and Abberline becomes the twins' contact inside the police. The memory's name plays on the famous line attributed to Henry Morton Stanley on finding David Livingstone.
The sergeant's disguise as an old woman is so poor that Jacob pulls off the bonnet, nearly blowing his cover. He asks the twins to bring in names he supplies, quietly and within the law, since dead bodies at the station would cause him trouble. Dalton protests that half the rich men in London squeeze tenants the same way.
Gang War: Whitechapel
Gang War: Whitechapel is the showdown for the borough: with Henry's new kukris, you lead the Rooks against Rexford Kaylock's Blighters at the Whitechapel train station, then chase Kaylock along the roof of his moving train. Winning gives the twins their Train Hideout.
Somewhere That's Green
Somewhere That's Green is the first London memory: as Jacob you step off the train in Whitechapel, chase a pickpocket, race Evie up a factory roof and meet Henry Green, the Assassin who has been watching over the city. It ends with a carriage chase to shake off Blighters.
To Catch an Urchin
To Catch an Urchin is where the twins meet Clara O'Dea and her network of child spies in Babylon Alley. Her price is a favour: free the children working in a Blighter-run factory warehouse.
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.
