"A Slip of the Tongue" is a Traffic case that focuses on a grand theft auto.

When a suspect caught behind the wheel of a stolen car claims to have bought the vehicle fair and square, Detectives Phelps and Bekowsky are unimpressed. When he produces a pink slip and bill of sale as proof, they sit up and take notice. There follows an investigation that will throw up bumbling car thieves, double talking auto dealers, and a theft racket that stretches across Los Angeles and the state line.
