The muzzle flamed as she laid down continuous fire. Confused, I swung about, looking for targets, but the killing floor was deserted except for the remains of Kadmin. Carnage was nowhere in sight, and between explosions the noise of the crowd had changed abruptly to the hooting sounds of humans in panic. Everyone seemed to be on their feet, trying to leave. Understanding hit. Trepp was firing into the audience.
