In 'The Thin Man' (1934), young Dorothy Wynant (Maureen O'Sullivan) approaches amateur sleuth Nick Charles (William Powell) when her inventor father appears to be a major suspect in a murder case. In fact, Dorothy is so worried about her father's guilt that she tries to convince Nick that she did it. Nick's wife Nora (Myrna Loy) wants him on the case so that she can experience some of the excitement herself. However, Nick is reluctant to get involved until he sees that police Lt. Guild (Nat Pendleton) is coming to the wrong conclusions. Nick decides that the best way to clear up the case is to invite all the suspects to dinner with Lt. Guild and see what happens. In 'After the Thin Man' (1936), back in San Francisco after solving their last case in New York, Nick and Nora find another case. Nora's cousin Selma (Elissa Landi) is accused of having murdered her husband, but for Nick it's clear that she is not the murderer and he starts to investigate.
