Malcolm Black

Malcolm Black is an illegal arms dealer that held captive David Clarke for 10 years. He faked David's death during 2002 as a cover to break him out of prison and force him to launder money for him. He is the father of Katherine Black (formerly known as FBI agent Kate Taylor).

Season 4
Malcolm Black makes his first appearance in "Epitaph" after failing to make contact with Kate whom he had sent to the Hamptons to track down the money that David Clarke stole from him when he escaped.
