Mystery of Marie Roget

This cast of B actors carries off a well-written murder mystery by Edgar Allan Poe. The sister of a woman about to inherit a large fortune plots her murder. But then she herself disappears. Who killed her? Her boyfriend (who was also courting the sister), her grandmother, her estate manager. Or her sister, to protect herself?

The events unfold with a number of false leads and dead ends, and with a few red herrings. However, due to the brilliant detective work of Dr. Dupin, who plays a Sherlock Holmes-type character to the local police chief's Watson-type character. The formula works to a degree, and we have an entertaining mystery.
