Nisao’s face tightened, and despite the ward, she looked over her shoulder as if she feared someone might be listening at the entry flaps. “The workmen thought they had eaten badly preserved mushrooms. Some farmers are careless in gathering what they intend to sell, and the wrong sort can paralyze your lungs or make your throat swell up, so you die struggling for air.” Egwene nodded impatiently. She had grown up in a country village, after all. “Everyone seemed willing to accept that,” Nisao went on, but she did not hurry. Hands twisting and flexing on the edges of her cloak, she appeared reluctant to reach her conclusion. “There were no wounds, no injuries of any sort. No reason to think it was anything but a greedy farmer selling bad mushrooms. But…” She sighed, glancing over her shoulder again, and lowered her voice. “I suppose it was all the talk of the Black Tower in the Hall today. I tested for resonance. They were killed with saidin.” A grimace of disgust crossed her face. “I think someone just wove solid flows of Air around their heads and let them smother.” Shuddering, she drew her cloak closer.

Egwene wanted to shudder, too. She was surprised she did not. Anaiya, dead. Smothered. A deliberately cruel way of killing, used by someone who had hoped to leave no traces. “Have you told anyone, yet?”

“Of course not,” Nisao said indignantly. “I came to you straightaway. As soon as I knew you’d be awake, at least.”

“A pity. You will have to explain why you delayed. We can’t keep this secret.” Well, Amyrlins had kept darker secrets, for the good of the Tower as they saw it. “If we have a man who can channel among us, then the sisters need to be on their guard.” A man who could channel hiding among the workmen or soldiers seemed unlikely, but less so than one coming there just to kill a single sister and her Warder. Which raised another question. “Why Anaiya? Was she just in the wrong place at the wrong time, Nisao? Where did they die?”

“Near the wagons on the south side of camp. I don’t know why they were there that time of night. Unless Anaiya was going to the privies and Setagana thought she need guarding even there.”

“Then you’re going to find out for me, Nisao. What were Anaiya and Setagana doing out when everybody else was asleep? Why were they killed? This, you will keep secret. Until you can give me reasons, no one but the two of us is to know you’re looking for any.”
