A black and white illustration of "The Shadow" character from the 1930s pulp fiction and radio series, featuring a dark-cloaked figure with a fedora and scarf covering most of his face, except for his piercing eyes and prominent nose. He stands with his hands at his sides, looking off to the side with a serious expression. The background is a textured, cloudy sky.

A car crash draws the attention of lawyer, Lamonte Cranston, and his secretary, Margot Lane. The petty burglar who died in the wreck is found with a valuable ruby that has an ancient curse on it. As Lamonte investigates, more details about the ruby and its strange curse emerge.

The ruby is returned to the famous actor who recently owned it, but is the curse causing deadly terror? What is really going on with the gunshots in the actor’s mansion, and the murder? The Shadow knows. Spooky things are afoot, and the truth of the mystery will be revealed when you listen in to join the Shadow as he lays his trap for the bad guys, and exposes the secret of the curse.

PS: Although, if you ask me, the killer is pretty dumb in his attempt to kill everybody in the house to try to get the ruby.

Note: I’m not sure about the date. The sound quality seems to be right for the era, but at the time, Orson Wells was the voice of the Shadow. Also, near the end Margot Lane mentions the year being 1947. The calendar date fits in better with being an episode from 1947 as well.
