From Hell is the first Ripper Letters activity in the Jack the Ripper DLC: handwriting experts have named a suspect for a new letter, and Arthur Weaversbrook asks Evie to make sure he is not the real killer.
Find the suspect and tail him through the borough until he stops to boast to friends about fooling the police and making the front page. Frighten him, catch him and hear his confession, then let him go.
The real 'From Hell' letter was the last of the well-known Ripper letters, postmarked 15 October 1888 and received by George Lusk of the Whitechapel Vigilance Committee, so using it first is out of order.
Weaversbrook first printed a Ripper letter with police backing, hoping a reader would recognise the handwriting. Jack then threatened him into printing more, and the coverage made Weaversbrook Publishing the best-read press in London. These three memories are his attempt to make amends.
The suspect wanders the borough before he stops. Keep him in sight without crowding him, since the confession only comes once he relaxes with his friends.
The full text of the real From Hell letter is reused in the hidden Eagle Vision messages Jack leaves for Evie in The Mother of All Crimes.
Dear Boss
Dear Boss is the last Ripper Letters activity in the Jack the Ripper DLC: Weaversbrook needs to know whether the 'Dear Boss' letter came from a madman or a newspaperman, so Evie follows its suspected author to a dockyard and makes him talk.
Jack's Lieutenants: City of London
Jack's Lieutenants: City of London is an assassination activity in the Jack the Ripper DLC: four of Jack's gang bosses meet at Cannon Street station, and Evie infiltrates the station to kill them all for Arthur Weaversbrook.
Saucy Jack
Saucy Jack is the second Ripper Letters activity in the Jack the Ripper DLC, named after the real 'Saucy Jacky' postcard. Evie runs down its supposed author for Arthur Weaversbrook and finds a man with a political motive.
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.
