Bosch's contact with Vance takes extreme liberties with its relationship to Raymond Chandler's 1939 novel "The Big Sleep." Vance and the case are nearly identical.
Mark Ralston, as Lt. Thorne, assigns Maddie Bosch to 'Officer Vasquez' as her new T.O. In 'Aliens', he portrayed a Marine named Drake, whose squad mate was a female Marine named 'Vasquez'.
The actor is playing the character Carl Rogers in Legacy and the original Bosch series are different.
