This is an excellent cozy mystery, with enough of a veneer of noir to appeal to even those who are indifferent to the genre. The chemistry between William Powell and Myrna Loy is as palpable as it is adorable, and somehow manages not to detract from the mystery but enhance it. Everyone is a viable suspect until the last clue is in place, and the mystery comes together very well in the end.
Closest comparison: It’s like Partners in Crime (1983) by way of The Maltese Falcon.
Setting: Noir
Plot: Mystery
Tone: Romantic Comedy
