In 1868, as a young member of the Metropolitan police force trying to make a name for himself, Sergeant 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.

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.

He later aided Jacob further in their investigation, Jacob uncovering Plutus' identity as the banker and Templar Philip Twopenny as he provided information regarding the bank's possible access points.

However Jacob's assassination of Twopenny and the Earl of Cardigan caused major turmoil in London's citizens and Abberline had to calm the rioters down. He met with Evie Frye who, once again, came to fix her brother's problems. She had to recover the currency printing plates, after Abberline informed her that Jacob was accused of stealing it. Abberline also requested to destroy counterfeit notes if Evie had the opportunity.

After Maxwell Roth's assassination, Jacob asked Abberline ideas on how to smuggle weapon inside a ball to be held at the Buckingham Palace. The sergeant told him to acquire the royal guards' uniform and to return a carriage Jacob evidently stole. After acquiring the uniform, Jacob gave it to Abberline for his disguise. He told him to meet him on the roof of the palace.

Later, at the ball, Abberline informed Jacob that Starrick's men had replaced the rooftop guards and had taken up sniping positions. Though Abberline was uncertain who the impostors were, Jacob assured him that he had the means of identifying them.

The next morning, after Jacob, Evie and Green had assassinated Starrick, Abberline brought them to meet Queen Victoria, who knighted the trio into the Order of the Sacred Garter.

In 1888, he worked with the Assassin Order to find the serial killer known as Jack the Ripper.
