Another Thin Man (1939)
by Hans J. Wollstein review

Too much plot tends to get in the way of the usual verbal sparring between the Charleses, Nick (William Powell) and Nora (Myrna Loy) , in this the third entry in M-G-M's series of sophisticated whodunits. Not that Nick and his charming wife aren't their usual brittle selves but the screenwriters dragged in almost to burdensome a riddle for them to solve. The end result is fairly entertaining, though, especially when Mr. Charles' addlebrained gangland pals insist on given little Nick, Jr. (William A. Paulsen) a birthday party complete with "rented" baby guests.
