A famous detective gets invited to a swanky party at an elegant mansion, but finds himself searching for a killer after a murder occurs at the mansion.
A few people are murdered, starting with gaily amoral Muriel Randall (Iris Adrian), who has divorced one elderly husband (he becomes corpse number two), driven a younger second husband to insanity (he ends up with Rigor Mortis, too) and advancing vampishly on his younger brother - apart from her flings, she is using her inside-knowledge of a gangland rub-out to extort booze and cash from local racketeer Gus Colleti (Noel Madison).
When Muriel turns up stabbed in bed, it's no wonder that everyone is suspect - and Bill is especially keen on proving that the pretty Jane Maxwell (Irene Ware), first wife of the second husband, didn't do it. Cause he fancies her ...
Murder at Glen Athol is a wellcrafted mystery with interesting suspects and a clever detective who is well played by John Miljan- his sidekick isn't too annoying as he provides some humour. This mystery can be taxing in a sense you have to pay close attention in terms of suspects or you get lost (I found myself rewinding a few times). However, it's an engaging film with good acting, breezy energy and a good finale that had my brain doing somersaults to keep up with the hero's explanation of who was the murderer, and his stiff "chicken" was the trigger.
