Here we've got a complete change of atmosphere for our city-dwellers Nick and Nora: they travel to Nick's small hometown to see his parents after a long time. And since Nick knows how much his father disapproves of his excessive drinking, he's gone on a 'diet' of... apple cider! But Father also disapproves of something else: that Nick didn't become a doctor like himself, but just a 'cop'... And yet that's exactly what's made him famous in his town: the many difficult murder cases he's solved in the city. And so everybody thinks, as soon as he turns up in the sleepy hole, that he must be here 'on business'... But while he's trying to persuade everyone that he's just on holiday - he DOES get his 'business': a young man is shot right in front of the door of his parents' house!
So, whether he wants to or not, he helps investigating (since the country cops are even dumber than those in the city...); and he uncovers not only a whole number of well-kept family secrets, but - with a painting that Nora buys him for his birthday and that seems strangely coveted by some people as evidence - finally a big case of industrial espionage! And as for the identity of the actual murderer: here he makes his father proud at last with his knowledge of forensic medicine...
Now, it depends on the point of view: you could call the environment in this movie either unusual or unsuitable for Nick and Nora. Anyway, let's see it from the positive side: William Powell and Myrna Loy are once again in great shape and in the mood for cheeky jokes (Nickie Jr. was left at home this time, so there aren't any parents' issues), Anne Revere gives a great performance as 'Crazy Mary' and Donald Meek as the nutty art dealer and Edward Brophy (who had played 'Morelli' in the original first "Thin Man" movie) as the chatty salesman provide good fun entertainment, and the plot is really quite clever and full of surprises.
Still, you can feel the atmosphere changing and drifting further away from the first 'Thin Man' movies; so, for fans of Nick and Nora (as we knew them from the 30s) this one might be a slight disappointment - but as a crime comedy on the whole it's certainly solid, well-made entertainment!
