Sister Marie told Carm that their meeting was about “oh, just something,” implying that there was no significant or serious matter to discuss.

Sister Marie intended to question Carm about the intimate details of her father’s death.

Sister Marie Howorth knew that this was a serious and sensitive subject, not a trivial matter.

Sister Marie Howorth deliberately described the meeting as insignificant to prevent Carm from anticipating the true nature of the conversation.

Therefore, Sister Marie Howorth lied to Carm about the purpose of their meeting.
