A Non-runaway Death[]

Main article: The Memoirs of the Clouded Kokoro

With John Garrideb

Duncan Ross was a student at Thorndyke Academy of Fine Arts. He was engaged to his fellow student Olive Green. Once he showed her how to pick a lock using a wire and some turpentine. He went to live in a cheap flat on Briar Road that used to be occupied by Selden, one of London's most notorious criminals, due to wanting a room with a history and to save money for his wedding with Green. William Shamspeare, the prisoner who took care of Selden, tried to scare him out by blowing into the gas pipes to search the room for a hidden treasure. This led people to believe that Selden now haunts the flat and curses future residents with death. Green tried to persuade him to move out in fear of the gas leaks. Ross promised he would soon leave and move to a better place, but he didn't want to live with her due to wanting to graduate before meeting her parents. However, later that night, he passed away via asphyxiation. As a result, Green dropped out of school and went by Briar Road many times.

A Vengeful Fiancée[]

In picture in Green's ward

After hearing what been going on in the flat from the new tenant, Soseki Natsume, at a pub and remembering a conversation between two gas company employees, Green realized Ross' death might not have been an accident after all. So she bought some strychnine off the black market and painted it on the gas pipe in Shamspeare's apartment. That way, it would confirm her suspicions and Shamspeare would receive his due punishment. She sent a letter for him to meet at the The Slug and Salad to lure him out but she didn't make it due to being stabbed by Joan Garrideb. At St. Bartholomew Hospital, she kept a picture of Duncan Ross on her desk.
