Detectives Briscoe and Curtis investigate the murder of Shelley Ganz who is found in her coop's parking garage shot in the back. Ganz was a financial analyst and apparently well-liked by everyone. She did work as the treasurer for her coop building but the police are unable to find any resident - or prospective resident - who might have an ax to grind. The do note that one of her neighbors, Susan Tashjian, bears a striking resemblance to the dead woman and wonder if she might have been the intended target. When she's gunned downed a few days later, it's obvious they were right. They quickly find the shooter and a pattern that leads them to unsolved murders. The common thread among all the victims is that they owed money to the Beechwood Loan Company owned by Sam "Bunny" Russo - who also had insurance policies on all of the victims.
