Echostreet Alley is a Lambeth gang stronghold under Cletus Strain, named for the screech of trains at Waterloo station echoing through its backstreets. Burn the Blighter heist plans and free the captured Rooks for full sync.
The leader, Tom, reads a letter from Strain about rogue twins stirring up London's underworld. Strain tells him to keep the Blighters in line and leave the brutality to him, and admits the fight might cure his boredom.
Echostreet Alley and Battersea Bellows are Cletus Strain's two strongholds. Lambeth's Templar hunts are Martin Church, the Lambeth Bullies and the Fletchers, and its bounties are Leopold Bacchus, Mildred Graves and Jesse Butler.
Look for the Blighter heist plans and set them on fire, and free the captured Rooks and keep them alive. The heist plans can be burned at any point, but the prisoners are vulnerable once fighting starts, so it helps to clear guards around them before you cut them free.
Strain warns Tom that the twins may already have taken out several borough leaders and tells him to stay calm. The letter hints the raid comes after the Fryes have made progress elsewhere in London.
