The Killer Instinct

A series of strange deaths sparks the interest of a police detective, especially when he learns of the unusual circumstances behind each victim's demise, and the involvement of a smooth-talking salesman.

A cop gets curious about weird murders after he finds out each person died in bizarre ways, and discovers a charming salesman is connected to all of them.

Harrison Craig has begged his wife, Marlene, to give him her $50,000 inheritance to invest in a new business venture. It was a sad coincidence that it took her death for him to get the money. Her physician, Dr. Bardel, goes straight to police lieutenant Barry, claiming Harry murdered his patient. When two more deaths help Harry’s new business venture, the case seems stacked against him. But then, one other possibility arises.
