This movie is pointless as a mystery and useless as a suspense film. All of the relevant information is provided too late for the audience to solve the mystery and early on the film makes it clear that it’s not playing fair. The twists and turns of the plot are often not even possible, let alone plausible, and the audience is left to simply take for granted everything that appears on screen. The acting is fine, but certainly a product of its time. This movie is a mostly unoffensive waste of time.
Closest comparison: It’s just another ‘mystery’ in the vein of The Cat and the Canary and The Riverside Murder.
