Jack the Ripper Activities are the 21 side memories in the 1888 DLC, spread across Whitechapel and the City of London. Abberline, Arthur Weaversbrook and Nellie each hand out a set, and together they weaken Jack's hold on London's criminals and brothels.
Track down a criminal wanted by Scotland Yard, kidnap him and deliver him alive to Abberline. Abberline complains if you bring him a corpse.
Find a shipment held by Rooks, clear them off and drive the cargo to a drop-off point for Weaversbrook. One load is opium, the other looted Egyptian antiquities.
Shut down Rook-run fight clubs where bouts go to the death, one at Mitre Square in Whitechapel and one under a pub on Cock Lane in the City of London. Both ask you to frighten 15 enemies.
Nellie reports a kidnapped woman. Check the kidnappers' carriages, hijack the one she is in and lose the pursuers. The second one takes place in the City of London.
Weaversbrook names the suspected author of a Ripper letter. Tail him until he brags, frighten him and catch him to learn the truth, then let him go.
Drive a real-life Ripper suspect to Scotland Yard for questioning while angry locals try to stop the carriage. Full sync asks you to stay undetected.
Hit gatherings of Jack's gang bosses: four at Cannon Street station in the City of London and five in Whitechapel.
Grab a man abusing a woman and march him through crowds in Whitechapel so people jeer at him, ending at Nellie.
Free Lady Owers' brothels at Ludgate Hill and Gracechurch Street in the City of London and Buck's Row in Whitechapel. Kill the thugs inside, then their leader outside, while keeping the women alive.
A Simple Matter of Murder!
A Simple Matter of Murder! is the first Dreadful Crimes case: a foreman lies stabbed in a Whitechapel warehouse and a boy is found holding the bloody knife. Henry Raymond and young Artie introduce themselves and challenge you to solve it, and the obvious answer turns out to be wrong.
Abberline, We Presume
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.
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.
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.
