I was reading the review by Calvinnme and agree heartily. If the viewer never saw the previous Hildegard Withers films that starred Edna May Oliver, you might enjoy "Murder on a Bridle Path" even more. While Helen Broderick is very good in this role, Oliver was just better as Hildegard. Apparently, Oliver and the studio had a 'parting of the ways' and they unsuccessfully tried Broderick and later Zasu Pitts in Oliver's place. But, no matter how they tried, no one could match the charming crankiness of the original!
The film starts with a blonde lady being disagreeable with several folks--a clear giveaway that she'll soon be murdered (it's a standard cliché in mystery films of the time). VERY soon after, she's killed while out riding her horse. Again, Calvinnme was right--this character wasn't developed enough and her death came too quickly. The police assume she died by accident but soon they notice a few clues that indicate she was NOT killed by being kicked by a horse. Around this time, Hildegarde shows up and immediately begins digging for clues. Like any murder mystery of the era, there are lots of dead ends and twists--along with a VERY florid ending involving the murderer--and it's by far the best part of the movie.
This is a pretty good mystery film. Unfortunately, the snappy dialog from Withers isn't as obvious--not just due to Broderick but because the writing is a bit less snappy. Enjoyable but that's really about all.
