Mary Ann Nichols (Assassin)

An unidentified British Assassin initiate (unknown - 31 August 1888) was active during the Whitechapel murders and the first real victim of the Assassin turncoat and serial killer Jack the Ripper.

Biography
During her childhood, the Assassin initiate was recruited by the Master Assassin Jacob Frye sometime after the British Rite of the Templar Order Grand Master Crawford Starrick's death, in order to rebuild the British Brotherhood. Along with other initiates, she was brought to India by Jacob to learn the fear tactics of the Indian Assassins.

By their return in 1888, a fellow initiate Jack usurped control of Jacob's gang the Rooks and started operations to eliminate the Assassins. In an attempt to stop his former student, Jacob sent his initiates to pretend to be prostitutes as undercovers.

After Jacob sent the real Mary Ann Nichols away from Whitechapel, he ordered the apprentice to assume her identity. The initiate then tried to assassinate Jack the Ripper in the morning of 31 August but failed, resulting to her demise.

The Inspector Frederick Abberline and Jacob's twin Evie Frye discovered her guise during their investigation, seeing an Assassin ring in the crime scene. She was buried in 6 September 1888.
