Benjamin Lambert is the police chief of the Saint Denis Police Department.
The player can hunt down Lindsey Wofford as a bounty, for a $100 reward. If Wofford is brought in dead, Lambert will ask for his body to be dumped in a cart behind the police station or, if brought back alive, Lambert will ask the player to put him in a prison cell.
Benjamin Lambert also appears in stranger side-mission “The Mercies of Knowledge IV”. In this mission, the player must ask Lambert for a permit to publicly demonstrate Andrew Bell III's electric chair. Lambert sets the price at $100, but after negotiating with him, the price can be cut in half.
It is hinted at that he may have been forcefully bribed by Guido Martelli in 1907 to ignore his organisation's criminal activities.
Outside of missions, the player can find Lambert standing at the reception desk of the police station in Saint Denis.
Benjamin Lambert is a white middle-aged to elderly man with dark brown hair and a brown handlebar mustache. He wears a blue police uniform, complete with a blue peaked hat upon his head.
