Marylebone Church is an Anglican cathedral located in the Marylebone Road in London.


During the mid-19th century, a particular headstone of the graveyard in Marylebone Church was used as a signal by the British Assassins, specifically Ethan Frye and the Indian Assassin Jayadeep Mir.

Every evening, Jayadeep was required to check the headstone's position: upright signifies no messages, leaning right with danger and left as a meeting. During one of his checks, he witnessed five men harassing an old woman in the churchyard. He immediately locked them into combat and saved the woman who was named Maggie.
