Given the following context:  Lyon Gaultier is a paratrooper in the French Foreign Legion, stationed in Djibouti, North Africa. His brother, who is married to an American woman in Los Angeles, is burned alive during a drug deal gone wrong and suffers third-degree burns, dying shortly afterward. Lyon deserts his legion when he finds out they have been withholding letters from his brother's wife and ultimately refuse to let him see his dying brother. He steals a jeep and escapes through the desert, finding work on a tramp steamer headed for the U.S. Meanwhile, the Legion Commandant travels to Paris, arriving at the government Consulate, where he is told that Lyon's desertion is ranked at low importance with the LAPD, so the Commandant suggests sending two of his own men to bring Gaultier back, which is approved. Lyon arrives pennyless in New York City and is attracted to an illegal street fighting match that is being run by a New Yorker called Joshua, a man who runs fights for money. Gaultier steps forward to take part in the next fight and destroys his opponent, leaving Joshua looking astounded at what he just saw. Joshua takes Lyon to meet a person called Cynthia, also known as 'The Lady' who organizes underground fights for the rich elite and she decides to sponsor him. Figuring that this would be the best way to earn the money he needs to get to L.A., Lyon fights in a no-holds-barred bare-knuckle fights to finance the trip. Once in L.A. Lyon goes to the hospital where his brother was taken. He learns that he cannot avenge his brother's murder, as he failed to identify his killers before dying. Grief-stricken, Lyon asks the help of Joshua who tracks down his brother's widow's address. However she refuses to accept any financial aid from him, even though she obviously needs it, because she is angry with Lyon for "deserting" his brother years ago. She threatens to call the cops and Lyon has no choice but to leave.  answer the following question:  What is the full name of the person who finds out his legion has been withholding letters from his brother's wife?
