[1][2][3] Dorothea Kent played the romantic interest as the commander’s daughter, Genevieve, who studied criminology in college and is determined to help Renfrew solve the case, much to his disgust.

When one of the Maxwell Company’s armored cars disappear with a gold shipment, the missing driver, Bob Hill, is suspected of theft.

In actuality, Maxwell and his henchmen had poured acid on the truck’s brake lines, causing the vehicle to crash into a mountain lake.

When Renfrew appears at the garage to arrest Maxwell, the villain and his men speed away in an armored truck… but the air brake collapses, which results in the gang meeting the same fate as the first driver.
