Part 1: Ghost Town
1- The Assassin Ethan Frye was watching and tracking a target in a market.

2- The thief and courier Boot was headed down to deliver photographic plates in the St. Giles Rookery when he was threatened and interrogated with a Hidden Blade by Ethan.

3- Boot was about to reveal his boss' identity when he was shot by an unidentified individual. The man also tried to shoot Ethan, however, the bullet killed an innocent girl bystander. Enraged, Ethan chased and assassinated the man, who was revealed to be Boot's boss and Templar associate Robert Waugh. Later, Ethan reported the incident to his friend George Westhouse. The pair formulated a plan involving The Ghost and the corpse of Waugh to uncover the Templar plans.

4- The chief engineer John Fowler recollected his memories regarding the construction of the first underground railway. Touring the construction with his friend and solicitor Charles Pearson and his wife, they discovered the body of Robert Waugh in one of the construction trenches.

5- The manager Marchant informed the director Cavanagh of the crime, and Police Constable Frederick Abberline was called to inspect the crime scene. Abberline discovered that the cause of death was a clean stab wound. Despite Mary Pearson's request to delay the construction due to the death, Charles and Cavanagh insisted to continue the work. However, The Ghost, witnessed a look of recognition in Cavanagh as the latter gazed in the corpse. The Ghost signaled a drunk man after Abberline left with the corpse.

6- Reaching Belle Isle, Abberline tried to avoid the curious street children and eventually reached the mortuary yard. However, he discovered that Waugh's body had been replaced by a dead pony's corpse.

7- The Ghost returned home, passing by Marylebone Church to check messages. Sure enough, he learned that his handler wanted to see him. He returned to the Thames Tunnel and met with his friends Charlie, Jake and Maggie.

8- Remembering his childhood in Amritsar, India, Jayadeep/The Ghost recalled his father, Arbaaz, stories and his time training with Ethan Frye.
