Tony's mother was an alcoholic who allowed him to wander the streets on his own. One day, after stealing some food from the market, he was abducted by Marisa Coulter and taken to Bolvangar, where he underwent the process of intercision.
At Bolvangar, Tony became friends with a girl named Bridget McGinn. They were in the laundry room together when a nurse came and told Tony it was time for him to have an operation. Tony became a victim of intercision. Separated from his dæmon, he wandered to a village and stayed there in the fish house, holding a piece of dried fish as though it were Ratter.
Lyra Silvertongue found Tony and took him back to the gyptians. Tony couldn't calm himself without Ratter, though, and died the following morning. After Tony's death, the gyptians constructed a funeral pyre to cremate him. Lyra carved the name of his dæmon into a coin, then placed it into the boy's mouth like she had seen with the academics at Jordan College.
