Mabel gives Stephanie some photos she found in Fred's desk of half-opened garbage bags, containing dismembered human body parts.
Stephanie sees enough to identify the body as a woman's, and gives duplicates of them to her on-again/off-again boyfriend, Detective Joe Morelli, who passes them on to the sergeant in charge of the case.
Mabel tells Stephanie that Fred had been furiously pursuing RCG Waste Haulers to get his $2 back because they skipped picking up garbage at his house one time.
RCG (Ruben, Grizolli, and Cotell) had refused to refund him, because his payment wasn't in the system - they demanded to see his cancelled check.
Since the Fred mystery is on her own personal time, Stephanie is facing financial hardship and out of desperation she takes a job with Ranger's security company to make ends meet.
To add to all of Stephanie's problems, Morelli informs her that Benito Ramirez, the psychopathic boxer who attacked Lula and threatened her in One for the Money has been released from prison thanks to the work of expensive lawyers.
Stephanie, Grandma Mazur and Bunchy question the wife of the guy being cheated by the cable company, and found out John Curly had taken all the related cancelled checks.
Further investigating reveals that both the cable company and RCG are routing a small percentage of customer payments to a different bank - skimming funds for personal use.
While she is en route, with Grandma Mazur in the front seat, Briggs calls, having hacked the bank's records and found out that Allen was booked to fly out of the airport within the hour.
