John Billingsworth is the chief warder of Jack the Ripper's private prison on the hulks at Deptford, and Evie's target in the Prisoners memory. He oversees the hostages Jack uses to extort their families and runs the executions.
Old navy ships at Deptford hold Jack's captives in terrible conditions. Prisoners are starved and tortured until they write the Ripper's demands to their families. Billingsworth believes the work is right and necessary.
Evie goes to Deptford looking for Jack, who is not there. She frees a group of captives to draw off the guards, then sabotages the gallows in Billingsworth's quarters so the mechanism becomes the means of reaching him.
Evie hangs him by the leg with his own gallows and finishes him with the Hidden Blade. He claims the Ripper's work is Jacob's vision for London and dies before she can get Jack's location out of him.
Prisoners has two full sync goals: frighten four enemies aboard the prison boats, and get through without being detected. Evie's fear tools handle the first, and releasing captives to pull the guards away makes the second easier.
Jack the Ripper
Jack the Ripper is the serial killer at the centre of the Jack the Ripper expansion, set in Whitechapel in 1888. Evie Frye returns from India to hunt him, and you also play as Jack himself in several story segments, using his fear-based kit against civilians and police.
