The Ascetic's Plan to Infiltrate the Buddha's Group

A group was jealous of the buddha's group, and didn't like that he had favorability with the king. So they recruited a female ascetic to infiltrate his group in an attempt to exploit their weaknesses. They kill her on one of these occasions when they're debriefing her from her experiences over there,. And long story short, they place the blame entirely on the buddhams for killing her.
