What is the first name of the person whose superior is Frank Westlake?  Answer the above question based on the context below:  After World War II, immigrants in Cuba who are refused visas for various reasons try to sneak into the U.S. illegally with the help of a human smuggling ring run by Palinov, a Levantine café owner. Following the death of one immigrant, U.S. Immigration operative Pete Karczag is sent to Havana, where he poses as a Hungarian in need of Palinov's services. During his dangerous undercover investigation, Pete meets Marianne Lorress, a penniless Austrian refugee of the Buchenwald concentration camp who is waiting to be smuggled into the United States by Palinov. He decides to use her to obtain the place and time of Palinov's next operation. However Pete falls in love with Marianne, and deducing that she must give herself to Palinov in trade for the trip, talks her into staying in Cuba. Palinov discovers Karczag's true purpose and decides to use his own services. He exposes Pete to Marianne, who angrily decides to go ahead with the smuggling trip. Palinov tries to have Pete killed but the agent overcomes his would-be killer, gets the information from him, and reports it to his superior, Frank Westlake. Palinov flies to the United States with Marianne and the other smuggled passengers. However, the airplane is being tracked by U.S. Immigration and is unable to refuel in Florida. Palinov and his pilot crash-land in the Florida Everglades in one last desperate attempt to elude capture.
