This is quite an amusing radio goof... The mayor of San Francisco is supposed to be reading the intro to the show, but for some reason is not there. After a few seconds of radio silence, the script is thrust into the hands of the San Francisco Police Chief to read - without having had any preparation. 

The case itself is a robbery on Filbrick Street, where the thieves have entered the premises, found the occupants and escaped with over $25k of jewellery. Will they be brought to justice?
