Sequence 4 splits the twins between two leads: Jacob traces Starrick's Soothing Syrup back to its maker, while Evie chases the Templars' new Piece of Eden. Its seven memories end at Lambeth Asylum, and completing them unlocks the A Quick and Reliable Remedy achievement.
Henry explains that Starrick's Soothing Syrup is now the only medicine sold in Lambeth. Jacob follows a street seller to a distributor, wrecks the distillery with Darwin, scares a name out of Owen and finally walks into the asylum. Evie's thread runs alongside it: she raids Lucy Thorne's shipment, finds a coded notebook and uses it to search the Kenway Mansion.
1. The Crate Escape. 2. A Spoonful of Syrup. 3. Unnatural Selection. 4. On the Origin of Syrup. 5. Cable News. 6. Playing It by Ear. 7. Overdose.
Jacob kills Elliotson by hiding under a cadaver sheet, which shuts down syrup production. Evie learns that Edward Kenway found a Shroud of Eden and left clues to where it was hidden. Starrick's inner circle meets afterwards, and Lucy Thorne promises to deal with Evie.
Jacob's thread runs from the Starrick Brewing Company's factory and distillery through the Southwark Foundry fight club to Lambeth Asylum. Evie's runs from the docks where Thorne's shipment lands to the Kenway Mansion in Queen Anne's Square. Cable News takes either twin to College Wharf.
The Crate EscapeThe Crate Escape is Evie's first lead on the Templars' new Piece of Eden: Lucy Thorne is expecting a shipment at the docks, so you raid her cart, open the chest and flee in a carriage chase while Jacob drives badly on purpose.
Cable NewsCable News is a short side trip for Alexander Graham Bell: his telegraph cables never arrived, and an intercepted wire says the cargo is held at College Wharf. Bell also fits your gauntlet with a dart launcher for a hallucinogenic serum before you go.
OverdoseOverdose is the assassination of Dr John Elliotson inside Lambeth Asylum. As Jacob you explore the asylum, help a trapped nurse and stop a brutal electroshock session, then reach Elliotson's lecture theatre by hiding under the sheet of a cadaver.Charles Darwin's London Stories
Charles Darwin's London Stories are side memories in which the naturalist, a friend of the twins since the Starrick's Soothing Syrup affair, asks for help as his enemies turn from argument to threats. You protect a fossil, destroy toxic flowers, tear down smear posters and finally rescue Darwin himself.
Charles Dickens's London Stories
Charles Dickens's London Stories are a set of side memories in which the novelist recruits Jacob and Evie Frye into the Ghost Club and sends them after rumours of demons, hauntings and spectral thieves around London. Most cases end with a human culprit behind the supposed ghost.
Epilogue
The Epilogue in Assassin's Creed Syndicate's memory list holds one memory, Pressed Flowers, where Evie collects flowers around London for Henry Green's herbarium. Collecting every pressed flower is also tied to the Language of Flowers achievement.
Karl Marx's London Stories
Karl Marx's London Stories are five side memories in which the exiled philosopher asks the Frye twins to help London's working people rather than the comfortable citizens they have already helped. You shield his union meetings from police spies, expose a dangerous factory, stop a grieving worker's bomb plot and guard a rally.
