Jeff Duffy

Jeff Duffy (Birth name: Taylor Acosta), a character in the Veil of Secrets book, was one of the deputies of the Birchport Police Department and the main antagonist. He made his first appearance in Chapter 2.

Appearance
Jeff has brown hair, blue eyes, light skin, and a stubble. He wears a sand brown police uniform over a white top.

Personality
Although not much is known about him, he is shown to be timid and obedient towards his chief. He is also shown to be dimwitted given that he often says or does things that make himself and Walsh look foolish.

In Chapter 14, it is revealed that he is a cunning psychopath who is targeting the Sterlings for the death of his mother, Alanis Acosta. He ruthlessly guns down Tino Thompson, Chief Walsh, and Margaret, and takes Kate as his hostage after he learns of her pregnancy and locking you in a cell.

He feels that the Sterlings prevented him from his life of privilege and wealth, which caused him to be neglected and abused in foster homes. He believes that all the Sterlings are nothing but pure evil, and therefore must die. This is also his motive for kidnapping Kate: he didn't want her to become a Sterling and resented them so much that he wanted to erase the Sterlings from history.

If you choose to save him, he will show remorse for his crimes and the epilogue states he becomes a model inmate in prison.

Tommy Walsh
Jeff does whatever Walsh tells him without batting an eyelash, even degrading menial chores. This leads up to years of built-up resentment, causing Duffy to kill him in Chapter 14.
