The Testaments by Margaret Atwood:
On the fifth day there were six women in brown among the shooters. There was also an uproar, as one of them, instead of aiming at the blindfolded ones, pivoted and shot one of the men in black uniforms. She was immediately bludgeoned to the ground and riddled with bullets. There was a collective gasp from the bleachers.
So, I thought. That’s one way out.
