Working in cooperation with a US Postal Service inspector (Douglas Kennedy), Friday (Jack Webb) and Smith (Ben Alexander) search for a forger who has been stealing checks and bank statements from mailboxes. After interrogating a first-time offender who turns out not to be the man they're looking for, the two detectives are able to track down the actual perp with the help of the San Diego police department. In one of the series' sillier moments, all action stops dead in its tracks as Officer Smith (Ben Alexander) tries in vain to refold a portable raincoat! This episode is based on the Dragnet radio broadcast of May 24, 1951. ~ Hal Erickson, Rovi
