Murder on a Honeymoon opens aboard a seaplane flying several passengers out to a vacation destination: it's a neat opening scene that sets the plot in motion with a murder and introduces us to all of the suspects as well. Among those passengers is Hildegarde Withers, played one more time by the great Edna May Oliver, who is a bit sick during the flight but recovers nicely when the plane lands and it is discovered that a fellow passenger is dead.
James Gleason returns as Inspector Oscar Piper; it seems the murdered man was involved in a case his department is on, so he hops a flight himself and quickly joins his old collaborator Miss Withers. ("Hildegarde, you get screwier every day" is practically the first thing he says to her when they meet, thus quickly re-establishing their outwardly adversarial, genuinely affectionate personal relationship.)
Good photography—both of island scenes and in some atmospheric shadowy night shots—adds sparkle to a script that neatly balances comic banter with murder. A solid supporting cast features Leo G. Carroll as a big shot movie director (who carries a flask with two compartments in it—one containing the good booze he drinks, one stocked with the cheap stuff he shares with others) and Lola Lane as an aspiring actress hoping to catch his eye.
Overall, the suspense is a bit more taut, the solution more surprising than in the two previous Withers-Piper pictures; it's a top-notch B mystery.
Oliver, especially, is at her very best, especially when dealing with those who underestimate her—for example, the local police chief and doctor, who are beginning the murder investigation while still in their bathing suits: "Don't try to be impressive in that rig, my man," Miss Withers snaps when one attempts brusqueness. "You can't frighten me until you've put on your trousers."
