Nick and Nora Charles are asked by Phil Brant and Janet Thayar, who have just eloped, to help them after band leader Tommy Drake is killed at a society dance which Nick and Nora also attended. The police are looking to arrest Brant for the murder and while he claims he's innocent, Nick isn't too keen on having him in the house and turns him over to the police. As they look into the case, Nick and Nora learn that Drake wasn't very well liked and there are actually several people who benefited from his death. Drake owed money to loan shark Al Amboy, and Janet's father disliked Brant and may have set him up. Drake's girlfriend may have been having a fling with clarinetist Buddy Hollis, and he and Drake had a fist fight on stage during the festivities. Nick arranges for another party on the same boat where Nora notices something quite peculiar about one of the guest's jewelry. Written by garykmcd
Did Nick and Nora's swan song, "Song Of The Thin Man," tries too hard to be hip and cool? Yep.
Are some of the bits a tad forced? Yep. Is this, the sixth adventure of Mr. & Mrs. Charles, the worst in the series? Yep.
You know what that means? Yes, it means that the worst Thin Man movie is still better than most.
For Nick and Nora's final bit of sleuthing and their first in a couple years (since the wonderful Thin Man Goes Home), they enter the ultra-hip, ultra-cool, slanged-out world of jazz, courtesy of their tour guide, reed-man Keenan Wynn, who couldn't put together a sentence of straight Queen's English to save his shoe bottom (soul). Who killed the band leader? All I can say is, it wasn't Nick or Nora or Asta.
By 1947, William Powell's waistline has expanded and Myrna Loy long ago gave up the sheer, slinky gowns that had us all drooling, but they can still cut it, rug and all.
Were six Thin Man movies enough? Not for me.
