 Part 1: It s your typical Monday at Mathnet, except, George can t dance, don t ask him. Kate offers to teach him, and just as they are getting started, enter Sgt. Bill Dietrich. The Auto Theft Division is Swamped.... Thefts are up 295% over the last two months! The Mathnetters ask Debbie to start compiling a database, when.... Bill Dietrich s car is stolen! (TO BE CONTINUED...) Part 2: George coyly reveals that Sgt. Dietrich had been parked in a "No-Parking Zone", and they take him to retrieve his car. While there, they run into Li-So, a recently licensed teenage driver who lost her mother s car to a Police Wrecker. George and Kate agree to help her, and Kate finds that, apparently, there is no wrecker 317 (the wrecker that towed Li-So s mother s car.) Debbie returns from crunching numbers, and finds, among other things, that large cars (e.g. Cadillacs Lincolns, and Station Wagons) are up theft-wise, cars are being stolen during the day, and LAPD has only been able to recover 30% of the cars stolen over the last two months. "What does it mean?" George asks. "It means that 20,000 cars have disappeared off the streets of Los Angeles in the last two months!"-Debbie replies. "Right off the face of the Earth..."-Kate. (TO BE CONTINUED.) Part 3- George is still trying to learn to dance, this time with a floor mat. No luck. Li-So returns, thinking that perhaps Wrecker 817 stole her mother s car. Unfortunately, 817 was in the shop for repairs. George subsequently reasons that if people are losing 10,000 cars a month, "they must be replacing them." Accordingly, Kate and George pay L.A. s largest used car salesman a visit, Art Fraud, Art Fraud Motors! His sales have been up, and he hasn t been seeing an increase in used cars being sold to him. The radio chimes in, and there are more complaints like Li-So s about LAPD Wreckers.... (TO BE CONTINUED.) Part 4- George and Kate meet with the Los Angeles Wharfinger, and determine that the cars couldn t have been shipped out by sea, or by air. After finding that the LAPD Wrecker drivers are "above reproach", Li-So and Debbie deduce that it could be a phony LAPD Wrecker driver. Kate gets an order from Chief Green taking all the official LAPD Wreckers off the streets for two days. The Mathnetters try and figure out what happened to the stolen cars, and wonder if the cars have been turned into scrap metal. Driving Li-So home, the Mathnetters spot a phony wrecker towing a Limousine, and engage it in pursuit... (TO BE CONTINUED...)
