David Theroux

Chief Superintendent David Theroux (Erick Ray Evans) is the American second in command of Nathan Spring. Theroux, an engineer, started out in the US space program but quit and joined the European space effort instead. When he is introduced in the opening episode, "An Instinct for Murder", he is working as a traffic controller and part-time Star Cop on the European space station Charles de Gaulle. Movie buff Theroux generally tries to maintain an air of wise-cracking, cool detachment which breaks down only when he is forced in "This Case to be Opened in a Million Years" to face his morbid fear of radioactivity.
