Answer
"The Thin Man" is not a James Ellroy book. Ellroy is known for his crime fiction novels set in Los Angeles, often dealing with themes of corruption, violence, and redemption. His notable works include "L.A. Confidential," "The Black Dahlia," and "American Tabloid." "The Thin Man," on the other hand, is a mystery novel written by Dashiell Hammett, featuring the detective Nick Charles and his wife Nora.
