Loose Ends is the seventh Jack the Ripper memory: you play as Jack, returning to the Deptford garrison after Evie's raid to kill the witnesses and burn the evidence before the police can connect him to the Assassins.
Part 7 of 10 in Sequence 10: A Monster's Creed
Constables are already searching the garrison. Kill them as you move through, find each witness who is offering information (one about the Ripper letters, one a Templar trying to buy his freedom, one beside Billingsworth's body) and kill them too.
Go into two buildings to burn papers and the belongings of the people Jack held. One set of letters prompts him to say he will play 'Saucy Jack' again once Evie is dealt with.
Jack leaves Deptford preparing what he calls a masterpiece meant to draw Evie to him, which sets up the next memory.
As in the Prologue, you control the Ripper himself. Every witness has police with them, so expect a fight at each stop; with no full sync objective listed, there is nothing to lose by fighting in the open.
One prisoner tells officers that 'Mister Jack' owns the place, another offers to show them the Ripper letters he heard the Warder reading aloud, a third tries to buy his life with money and land in the colonies, and the last is found kicking Billingsworth's body. Jack sneers that the third is a Templar like all the rest.
Loose Ends happens on 9 November 1888, the same day as Prisoners, and picks up after Evie leaves Deptford. The memory's description frames it as Jack shielding his new Creed now that his hostage operation has fallen apart.
Prisoners
Prisoners is the sixth Jack the Ripper memory, dated 9 November 1888: Evie goes downriver to Deptford to free Jack's hostages from prison hulks and an old garrison, and to kill Chief Warder John Billingsworth, the hangman running the place.
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.
The Mother of All Crimes
The Mother of All Crimes is the eighth Jack the Ripper memory, set on 9 November 1888: Evie examines the scene of Mary Jane Kelly's murder, then follows a message from Jack back to the earlier murder sites in Spitalfields and Mitre Square, searching for clues without killing anyone.
