G-men track stolen Uranium-238 shipment using new radar technology; they also recruit the girlfriend of a gang member as an informant. Radar helps, but it takes an undercover blonde to really get the goods on criminal masterminds.—Mike Rogers <[email protected]>

In post-WWII America,Radar has been developed to such an extent that law enforcement agencies, seated in their headquarters, can twist a few dials and bring in, on a small television screen, a crisp picture of a roving stock-footage truck carrying uranium material, highly coveted by foreign powers in order to make atomic bombs and blow up the U.S.A. This advanced version of Radar can follow the car occupied by the crooks out to hijack the truck, and also the police car pursuing them after they hijack the truck. But, alas, this can only be done when the atomic material is in motion, and has little value when the crooks park the truck. So the lawmen have to send in a female mole posing as a moll.—Les Adams <[email protected]>
