Randy Evers Milhouse was now a licensed Private Investigator and this was his first case. On the recommendations of the County District Attorney, he is hired by an insurance company to ascertain that Laverne Sparks Payne and Linda Sparks Burns, daughters of Joseph Sparks, were the only rightful heirs to their now-deceased father's estate. According to Doctor Nelson, Sparks had died from a heart attack. But certain information surfaced that suggested that he could have died because of foul play. Following that revelation, other questions began to arise, such as why did Linda leave town before her senior year in high school? What did Levi Keys and Harold Burns have in common? Why are there break-ins to Randy's apartment? And why were people being murdered?
