Biogaphy
In 1868, as a young member of the Metropolitan police force trying to make a name for himself, Frederick Abberline enlisted the help of the Assassin Frye twins to help him solve cases of the members of the Templar-affiliated gang Blighters, paying the twins money to kidnap or kill the targets.[1][2]
Sometime later, Abberline disguised himself as a banker named Dredge to gain information in the inner sanctum of the Templar Grand Master Crawford Starrick's financial sector. Abberline uncovered a plot to rob the Bank of England while undercover. However, he was accidentally kidnapped by Jacob Frye who was investigating as well. Abberline revealed his disguise, informing Jacob of his discovery. The Assassin talked him into revealing confidential information of the supplier - Cockham Merchants.[2]
In 1888, he worked with the Assassin Order to find the serial killer known as Jack the Ripper.[3]
