THE KILLERS ARE KNOWN. THE REASON IS NOT.

When Evan Mercer is murdered outside a quiet suburban restaurant, witnesses agree on one impossible detail: his mother-in-law fired first, then placed the same handgun in her husband's hands.

The crime should be simple. Instead, every answer exposes another fracture?an unraveling marriage, forged financial records, a custody battle, buried resentment, and a family determined to control its own history.

As the evidence pulls Evan's wife between grief and blood loyalty, one question becomes more dangerous than who fired the fatal shots: Why did both of them have to pull the trigger?

Before the truth reaches a courtroom, one murder may become two?and the final answer may be buried with another body.
