Here's a short story:

"How did Norman know, Sister Emma?" 

"He overheard you and Aryan arguing. I suspect that he purposely overheard on you. Norman knew or concluded what profession Aryan practiced. He might well have followed Aryan on his explorations. Whether he did or not is beside the point. When Aryan came back yesterday afternoon, Norman certainly decided that he had made some find, for Aryan told Norman that he would be leaving for the capital to meet the detective the next morning. He probably followed Aryan to your room and overheard what passed between you. 

"Since you could not act against the law of man and God, he would serve a natural justice in his own way. He took the jar of poison hemlock from the chemistry shop and when Aryan asked for a drink, he supplied it. Norman did not know the precise quantity needed and so Aryan did not suffer the full effects until after the bell called the community into the dining hall for the evening meal." 

Abbess was following Sister Emma closely. 

"And then?" 

"Then I began my investigation, and then the detective arrived seeking Aryan for an explanation for his death." 

"But who killed Norman?" 

"Norman knew that sooner or later he would be discovered. But more importantly in his guileless mind there was also the guilt of having taken a man's life to be considered. Norman was a simple man. He decided that he should accept the punishment--the honor-price of a life. What greater honor-price for the life of Aryan could he offer than his own? He also took a draught of poison hemlock." 

There was a pause. (End of story)
