When real estate agent June Barnes is fatally stabbed at a Washington DC open house, two of her business cards are found torn into shreds at the murder scene.

Even though June had many enemies, it is not long before her fellow co-workers are living in fear. It seems that someone bent on revenge is targeting real estate agents. As the police begin their investigation, Jean Terrence, a shy and unsuccessful real estate agent suddenly becomes a prime suspect. But Jean's friend Rita is determined to save her; together, the two self-appointed detectives launch their own amateur investigation.

Soon, the women discover that few had access to the murder weapon a treasured silver letter opener and they are more familiar with the personality quirks of their oddly assorted cohorts better than the police. Could Harold, a brooding agent with a fondness for knives, be a suspect? Or is it Marian, the betrayed office beauty? Better yet, could it be Kevin, the repressed hanger-on?

In this classic mystery tale, Jean and Rita are on a mission to reveal the truth and, in the process, unveil unwelcome secrets that eventually push them toward a deplorable discovery.
