There is no doubt that Yolanda Saldivar pulled the trigger and killed Tejano superstar Selena Quintanilla Perez on March 31, 1995. But does anyone know what really happened in room 158 of the Days Inn moments before the crime took place?

Maria Celeste Arraras has many answers, and her unrivaled coverage of the murder, trial, and aftermath made her the undisputed expert on the Selena case. Arraras shares firsthand information about the crime and the people involved - including details of her headline-making jailhouse interview with Yolanda, who repeatedly spoke of "Selena's secret" - a powerful hidden piece of information that she refused to divulge in the courtroom but revealed to Arraras at length.

Many questions were raised, and not all were answered until this revealing interview shed light on the crime. Why was there a suitcase filled with Selena's clothes at the murder scene? What was the significance of the jeweled ring, adorned with the initial S, that fell from Selena's bloody fist? Who was the doctor from Monterrey who called himself Selena's confidant and business adviser?

Selena's Secret fits together the pieces of this puzzle and depicts what really happened on that rainy day in March.
