Two little girls, frozen in black and white. One picture worth killing for.

Federal prosecutor Lisa Waldren’s estranged father wants her to investigate a cold case from his FBI days. Lisa nearly refuses, even though a wrongly convicted man faces execution for murder. Then her father reveals a photograph: a little white girl playing alongside a little black girl at a civil rights rally in 1965 where the crime—the shooting of a civil rights leader—took place. She recognizes herself in the photo.

She was there.

Lisa agrees to help, resolved to boldly seek answers she’s skirted for decades. What she discovers are layers of deception, both personal and professional, reaching as high as the head of the FBI. Possibly even the president.

And though Lisa and the other girl may have escaped the 1965 shooting physically unharmed, her little friend, now grown, bears the scars of it. All because of the color of her skin. As Lisa and her father get closer to the truth, the real killer turns the hunt around.
