Nick and Nora have grown up in this Farewell to the series. It is still just as funny, but there is an underlying theme of duty and moral obligation that is missing from the previous entries as Nick and Nora try to find the killer. Keenan Wynn is hilarious as Klinker, a jazz clarinetist, and there's plenty of jazz music -- real jazz, when it was truly cool and the performers were super cool.
